Built from precision-cast <strong>304 stainless steel<\/strong> with a 12-2 tin-bronze worm wheel and electrolytically polished exterior, the EP-SSVF50 accepts IEC motor flanges from frame 63 up to frame 80, covering input powers typical of 0.37-0.75 kW hygienic drives. Its 134 mm body length and o95 mm input flange make it the natural upgrade path from the SSVF40 for higher-torque conveyor rollers, rotary filling heads, and continuous agitation duties. With eleven gear ratios from 7.5 to 100 and a choice of hollow bore, solid shaft, double shaft, flange, or torque-arm output configurations, the EP-SSVF50 adapts to virtually every hygienic drive scenario an engineer might encounter in a modern FMCG or processing facility.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/chinawormgearbox.xyz\/wp-content\/uploads\/2026\/05\/ssvf-stainless-steel-worm-gear-drive-2.webp\" alt=\"EP-SSVF50 stainless steel worm gear reducer side view\" style=\"max-width:100%;height:auto;border-radius:6px;margin:12px 0;\"\/><\/p>\n<h2 style=\"color:#1b4d2e;border-bottom:3px solid #1b4d2e;padding-bottom:8px;\">Technical Specifications<\/h2>\n<p><img decoding=\"async\" src=\"https:\/\/chinawormgearbox.xyz\/wp-content\/uploads\/2026\/05\/SSVF50-stainless-steel-reduction-gearbox-dimension.webp\" alt=\"EP-SSVF50 dimension drawing stainless steel worm gearbox\" style=\"max-width:100%;height:auto;border-radius:6px;margin:12px 0;\"\/><\/p>\n<div style=\"overflow-x:auto;\">\n<table style=\"width:100%;border-collapse:collapse;font-size:clamp(13px,1.8vw + 9px,16px);\">\n<thead>\n<tr style=\"background:#1b4d2e;color:#fff;\">\n<th style=\"padding:10px;text-align:left;\">Parameter<\/th>\n<th style=\"padding:10px;text-align:left;\">Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background:#f2f9f4;\">\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Model<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">EP-SSVF50<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Housing Material<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">304 Stainless Steel (precision cast)<\/td>\n<\/tr>\n<tr style=\"background:#f2f9f4;\">\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Worm Wheel Material<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">12-2 Tin Bronze<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Worm Shaft Material<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">304 Stainless Steel (hardened)<\/td>\n<\/tr>\n<tr style=\"background:#f2f9f4;\">\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Surface Finish<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Electrolytically polished<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Lubrication<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Fully synthetic worm gear oil (food-grade H1 option)<\/td>\n<\/tr>\n<tr style=\"background:#f2f9f4;\">\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Speed Ratios<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">7.5 \/ 10 \/ 15 \/ 20 \/ 25 \/ 30 \/ 40 \/ 50 \/ 60 \/ 80 \/ 100<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Overall Length<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">134 mm<\/td>\n<\/tr>\n<tr style=\"background:#f2f9f4;\">\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Height<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">92 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Input Flange (o)<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">o95 mm<\/td>\n<\/tr>\n<tr style=\"background:#f2f9f4;\">\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Output Bore (o)<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">o70 \/ o108 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">Mounting Thread<\/td>\n<td style=\"padding:9px;border-bottom:1px solid #c8e6d0;\">M8x10<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3 style=\"color:#1b4d2e;margin-top:20px;\">Compatible IEC Motor Flanges and Output Shaft Key Size (mm)<\/h3>\n<div style=\"overflow-x:auto;\">\n<table style=\"width:100%;border-collapse:collapse;font-size:clamp(13px,1.8vw + 9px,16px);\">\n<thead>\n<tr style=\"background:#1b4d2e;color:#fff;\">\n<th style=\"padding:10px;\">PAM-IEC<\/th>\n<th style=\"padding:10px;\">N(H8)<\/th>\n<th style=\"padding:10px;\">M<\/th>\n<th style=\"padding:10px;\">P<\/th>\n<th style=\"padding:10px;\">Ratio Range<\/th>\n<th style=\"padding:10px;\">Key<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background:#f2f9f4;\">\n<td style=\"padding:8px;text-align:center;\">80B5<\/td>\n<td style=\"padding:8px;text-align:center;\">130<\/td>\n<td style=\"padding:8px;text-align:center;\">165<\/td>\n<td style=\"padding:8px;text-align:center;\">200<\/td>\n<td style=\"padding:8px;text-align:center;\">7.5 &#8211;

Worm gearbox efficiency is typically 60-85% depending on ratio.<\/p>\n<p><strong>Output Configuration:<\/strong> Hollow bore (standard), single solid shaft (SS, d=25 mm, L=153 mm, M10x27), double solid shaft (DS, L1=199 mm), output flange (F, KA=90 mm), or torque arm (K1=100, G=14, KG=38.5, KH=10 mm).<\/p>\n<h3 style=\"color:#1b4d2e;margin-top:20px;\">Certifications and Compliance<\/h3>\n<div style=\"display:flex;flex-wrap:wrap;gap:12px;margin:10px 0;\">\n<span style=\"background:#1b4d2e;color:#fff;padding:6px 14px;border-radius:20px;font-size:14px;\">&#9989; CE Marking<\/span><br \/>\n<span style=\"background:#1b4d2e;color:#fff;padding:6px 14px;border-radius:20px;font-size:14px;\">&#9989; ISO 9001:2015<\/span><br \/>\n<span style=\"background:#1b4d2e;color:#fff;padding:6px 14px;border-radius:20px;font-size:14px;\">&#9989; FDA 21 CFR Materials<\/span><br \/>\n<span style=\"background:#1b4d2e;color:#fff;padding:6px 14px;border-radius:20px;font-size:14px;\">&#9989; RoHS Compliant<\/span><br \/>\n<span style=\"background:#1b4d2e;color:#fff;padding:6px 14px;border-radius:20px;font-size:14px;\">&#9989; H1 Food-Grade Oil Option<\/span><br \/>\n<span style=\"background:#1b4d2e;color:#fff;padding:6px 14px;border-radius:20px;font-size:14px;\">&#9989; Material Traceability Cert<\/span>\n<\/div>\n<h2 style=\"color:#1b4d2e;border-bottom:3px solid #1b4d2e;padding-bottom:8px;margin-top:32px;\">Frequently Asked Questions \u2014 EP-SSVF50<\/h2>\n<details style=\"border:1px solid #c8e6d0;border-radius:4px;margin-bottom:8px;padding:12px;\">\n<summary style=\"font-weight:bold;cursor:pointer;color:#1b4d2e;\">How does the EP-SSVF50 differ from the EP-SSVF40 and EP-SSVF63?<\/summary>\n<p style=\"margin-top:10px;\">The EP-SSVF50 sits between the compact SSVF40 (115.5 mm body, IEC 63-71 frames) and the heavy-duty SSVF63 (166 mm body, IEC 71-90 frames). The SSVF50 134 mm body and o95 mm input flange accept up to IEC 80-frame motors, filling the mid-power gap for applications requiring more torque than the SSVF40 but not the full output of the SSVF63.<\/p>\n<\/details>\n<details style=\"border:1px solid #c8e6d0;border-radius:4px;margin-bottom:8px;padding:12px;\">\n<summary style=\"font-weight:bold;cursor:pointer;color:#1b4d2e;\">Can I use the EP-SSVF50 on a variable frequency drive (VFD)?<\/summary>\n<p style=\"margin-top:10px;\">Yes. The EP-SSVF50 is VFD-compatible. However, ensure the minimum operating speed provides adequate lubrication oil splash to the worm mesh \u2014 typically above 300-400 RPM input. At very low speeds, forced lubrication or grease lubrication may be required. The synthetic oil fill helps maintain viscosity at both low and high operating temperatures typical in VFD applications.<\/p>\n<\/details>\n<details style=\"border:1px solid #c8e6d0;border-radius:4px;margin-bottom:8px;padding:12px;\">\n<summary style=\"font-weight:bold;cursor:pointer;color:#1b4d2e;\">What is the output shaft diameter of the EP-SSVF50?<\/summary>\n<p style=\"margin-top:10px;\">The EP-SSVF50 solid output shaft is d=25 mm with an 8 mm keyway (b1), key depth t1=28 mm, and M10x27 retaining thread. The single shaft length is L=153 mm; the double shaft extends to L1=199 mm. The hollow bore output flange option uses KA=90 mm with a bolt circle KQ=110 mm (KP=125 mm, 11 mm holes).<\/p>\n<\/details>\n<details style=\"border:1px solid #c8e6d0;border-radius:4px;margin-bottom:8px;padding:12px;\">\n<summary style=\"font-weight:bold;cursor:pointer;color:#1b4d2e;\">Is the EP-SSVF50 suitable for outdoor or wash-down environments?<\/summary>\n<p style=\"margin-top:10px;\">Yes. The 304 stainless steel housing and electrolytically polished surface provide excellent outdoor and wash-down capability. Sealing is via nitrile rubber (NBR) or optional food-grade PTFE lip seals. For IP69K wash-down duty or aggressive chemical environments, specify stainless fasteners and confirm seal material compatibility with your cleaning agents with our engineering team.<\/p>\n<\/details>\n<details style=\"border:1px solid #c8e6d0;border-radius:4px;margin-bottom:8px;padding:12px;\">\n<summary style=\"font-weight:bold;cursor:pointer;color:#1b4d2e;\">Which mounting orientations are supported by the EP-SSVF50?<\/summary>\n<p style=\"margin-top:10px;\">The EP-SSVF50 supports horizontal input shaft (standard), vertical input shaft (motor above or below), and wall-mount orientations. Changing mounting position may require an oil level adjustment or a change to the oil fill quantity. Consult the installation guide or contact Ever-power engineering for non-standard mounting orientations to ensure correct lubrication.<\/p>\n<\/details>\n<details style=\"border:1px solid #c8e6d0;border-radius:4px;margin-bottom:8px;padding:12px;\">\n<summary style=\"font-weight:bold;cursor:pointer;color:#1b4d2e;\">Does the EP-SSVF50 worm gear require run-in?<\/summary>\n<p style=\"margin-top:10px;\">New worm gear sets benefit from a running-in period of approximately 200-400 hours at 50-75% of rated load, during which the contacting surfaces micro-polish to optimum contact geometry. During this period, gearbox operating temperature may be slightly elevated and efficiency somewhat lower. After run-in, efficiency improves and thermal output stabilises at design levels.<\/p>\n<\/details>\n<details style=\"border:1px solid #c8e6d0;border-radius:4px;margin-bottom:8px;padding:12px;\">\n<summary style=\"font-weight:bold;cursor:pointer;color:#1b4d2e;\">Are spare seals and wear parts available for the EP-SSVF50?<\/summary>\n<p style=\"margin-top:10px;\">Yes. Ever-power stocks shaft seals (input and output), bearing sets, and bronze worm wheel replacements for the EP-SSVF50. Providing the model number and serial number when ordering ensures correct part compatibility. Preventive seal replacement at 8,000-10,000 operating hours is recommended for continuous-duty installations.<\/p>\n<\/details>\n<p><script type=\"application\/ld+json\">{\n    \"@context\": \"https:\\\/\\\/schema.org\",\n    \"@type\": \"FAQPage\",\n    \"mainEntity\": [\n        {\n            \"@type\": \"Question\",\n            \"name\": \"How does the EP-SSVF50 differ from the SSVF40 and SSVF63?\",\n            \"acceptedAnswer\": {\n                \"@type\": \"Answer\",\n                \"text\": \"The SSVF50 sits between the compact SSVF40 and heavy-duty SSVF63, accepting IEC 63-80 frame motors with 134mm body, filling the mid-power gap.\"\n            }\n        },\n        {\n            \"@type\": \"Question\",\n            \"name\": \"Can I use the EP-SSVF50 on a VFD?\",\n            \"acceptedAnswer\": {\n                \"@type\": \"Answer\",\n                \"text\": \"Yes, VFD-compatible.
