EP-SSRV075 Stainless Steel Worm Gearbox — Product Overview
When a food processing plant needs to drive heavy bulk material conveyors, large mixing tank agitators, or multi-zone inclined transfer belts with a gearbox that withstands industrial-scale corrosion, engineers consistently turn to the EP-SSRV075. This large-frame model features a 75 mm centre distance and a 28 mm output shaft — larger than the SSRV063’s 25 mm shaft — delivering elevated output torque for heavy-duty continuous-duty cycles. Marine-influenced coastal food plants, offshore processing vessels, chemical manufacturing facilities, and large-scale beverage or dairy production all use the SSRV075 where daily CIP cleaning cycles expose every surface to caustic chemicals and high-temperature steam. The precision-cast 304 SS housing, 304 SS wheel core, 12-2 tin bronze worm gear, and fully synthetic gear oil create a drivetrain that outlasts any aluminium or cast-iron alternative in these conditions. Uniquely, the SSRV075 is compatible with IEC 100/112 frame motors — enabling 1.5–3 kW input power — making this the model of choice for significant mechanical work in a hygienic stainless format.

Core Features & Engineering Advantages

📈 High-Torque Stainless Platform
The 75mm centre distance and 28mm shaft deliver the highest compact-model torque in the SSRV series before the SSRV090 — appropriate for large food processing agitators, heavy conveyor chain drives, and primary material-handling equipment in a fully hygienic stainless housing.
⚙ IEC 100/112 Frame Compatibility
Uniquely in the compact SSRV series, the SSRV075 accommodates IEC 100/112B5 and 100/112B14 flanges, opening the 1.5–3 kW motor power range — allowing specification of heavy industrial loads without stepping to a more expensive planetary or helical stainless solution.
🌊 Marine & Coastal Performance
Coastal food processing plants and offshore aquaculture vessels face extreme atmospheric corrosion from salt-laden humid air. The SSRV075’s 304 SS precision-cast housing and polished exterior provide multi-year service life with minimal preventive maintenance in this environment.
🔒 Self-Locking on Ratios ≥30:1
For heavy bulk conveyors, self-locking at ratios ≥30:1 prevents loaded belts from running back after motor stop — protecting both personnel and downstream equipment from uncontrolled motion events on power interruption.
📋 Heavy-Duty 304 SS Torque Arm
K1=200mm arm length and R=30mm, scaled for the elevated reaction forces of the larger centre distance. Eliminates the need for a full gearbox support frame in shaft-mounted conveyor roller applications.
Application Industries & Typical Use Cases

Marine food processing operations — fish meal plants, seafood canneries, aquaculture processing vessels — represent the most demanding application environment for any industrial gearbox, and the EP-SSRV075 is specifically designed to excel here. Salt spray, seawater splashing, brine washing, and continuous high humidity all combine to corrode standard gearboxes at an accelerated rate. Coastal beverage plants and large-scale dairy processors rely on the SSRV075 for primary chain conveyor drives and large agitator assemblies where the SSRV063 cannot meet torque requirements.
🌹 Marine & Seafood Processing
Fish meal conveyor drives, seafood blanching chain drives, and brine tumbler agitators on processing vessels and coastal plants. SSRV075 resistance to salt spray and brine makes it the only viable compact stainless option for continuous offshore use.
🍾 Large-Scale Dairy & Beverage
Large dairy blending agitators, cheese vat stirring drives, and keg-washing carousel primary drives. IEC 112 motor compatibility allows the higher power motors needed for full-sized production equipment.
⛈ Chemical & Water Treatment
Thickener rake drives, chemical dosing tank agitators, and clarifier inlet valve actuators. Higher torque output and superior chemical resistance over aluminium make the SSRV075 the reliable long-term solution.
