✓ Core Features & Engineering Advantages
⚡ Inherent Self-Locking at High Ratios
At reduction ratios above 30:1, the EP-SSGM30 delivers natural self-locking behavior — eliminating the need for external brakes on vertical-load conveyors, gate actuators, and lifting mechanisms. This reduces BOM cost and simplifies machine safety design.
🆕 Food-Grade Hygienic Construction
The fully machined 304 SS housing has no exposed casting pores or painted surfaces. Combined with IP65 sealing and food-safe synthetic gear oil, the EP-SSGM30 complies with hygiene requirements for direct-line food and beverage processing equipment.
🔌 Low-Noise, Smooth Power Transmission
The 12-2 tin bronze worm wheel absorbs vibration and provides quiet meshing, making the EP-SSGM30 ideal for noise-sensitive pharmaceutical labs and cleanroom packaging environments where motor-gear noise compliance is mandatory.
🔍 Compact Size 30 Frame — Space-Saving Design
With a 30mm center distance, the EP-SSGM30 is the most compact unit in the SSRGM range. It fits inside cramped machine enclosures and replaces bulkier, heavier alternatives while delivering the same corrosion resistance — critical for OEM space-constrained builds.
🔨 Universal Mounting & Multi-Shaft Configurations
Available in A/B single solid output shaft, D protective cover, and E torque arm configurations, the EP-SSGM30 adapts to virtually any machine mounting orientation. IEC-standard B5 motor flanges (56–80 frame) ensure direct-drive compatibility with global motor brands.
🏢 Application Industries & Typical Use Cases
🍔 Food & Beverage Processing
The EP-SSGM30’s fully stainless exterior and hygienic synthetic oil make it a natural fit for filling machines, portion control conveyors, rotary table drives, and auger feeders in meat, dairy, and dry-goods processing. Daily CIP wash cycles cause no corrosion or paint flaking into product streams.
💊 Pharmaceutical & Chemical Equipment
Compact worm gear reducers for pharmaceutical blending tumbler drives, chemical dosing pump actuators, and cleanroom conveyor speed controllers demand both precise speed reduction and contamination-free materials — exactly what the EP-SSGM30 delivers in a size-30 form factor.
🛍 Conveyor & Material Handling
For small-pitch belt conveyors, roller drives, and incline conveyor head drums, the EP-SSGM30 provides reliable torque multiplication in a corrosion-resistant package. Its self-locking trait at high ratios removes the need for a separate holding brake on inclined conveyor sections.
💧 Water & Wastewater Treatment
In humid, chemically aggressive water treatment environments, the 304 SS housing resists chlorine, sulfate, and oxidizer corrosion far better than standard cast-iron units. The EP-SSGM30 drives small valve actuators, metering pump heads, and screen wiper mechanisms reliably.
📚 Selection Guide, Certifications & FAQ
How to Select the Right EP-SSGM30 Configuration
Start by determining your required output torque (Nm) and output speed (RPM). Divide your motor speed by the desired output speed to find the required reduction ratio — choose the closest standard ratio in the EP-SSGM30 range (5–80). Verify the output torque does not exceed the rated torque for that ratio at your input power. For inclined or vertical load applications, select ratios ≥ 30:1 to benefit from self-locking without an external brake. Match your motor IEC frame size (56–80) to the corresponding B5 flange option.

❓ Frequently Asked Questions — EP-SSGM30
What is the maximum output torque of the EP-SSGM30?
The EP-SSGM30 is the smallest unit in the SSRGM series with a 30mm center distance. Output torque capacity depends on the selected reduction ratio and input motor power; typical ratings range from approximately 3 Nm to 15 Nm across the ratio range. For precise torque capacity at your specific ratio and input power, please request the full technical datasheet from our sales team. Always include operating duty cycle and ambient temperature in your inquiry for accurate sizing.
Is the EP-SSGM30 suitable for food-contact environments?
Yes. The housing is precision-cast 304 stainless steel with all six sides machined for a smooth, cleanable surface. The unit uses fully synthetic food-compatible worm gear oil and is rated IP65 for washdown resistance. These characteristics make it appropriate for indirect food-zone applications such as conveyor drives, filling machine actuators, and packaging equipment where hygiene standards must be maintained. For direct food-contact applications, consult our team for FDA-grade lubricant options.
Which motors are compatible with the EP-SSGM30?
The EP-SSGM30 accepts IEC standard B5 flange motors in frame sizes 56, 63, 71, and 80. Both single-phase and three-phase AC motors with these IEC frame dimensions mount directly without adapter plates. Standard motor shaft diameters for these frames (9mm–19mm) are accommodated by the input bore. Confirm shaft diameter against the dimension table before ordering. VFD-compatible motors can also be used to achieve variable output speeds across the EP-SSGM30’s full ratio range.
Does the EP-SSGM30 self-lock when power is removed?
At reduction ratios of 30:1 and above, the worm gear geometry of the EP-SSGM30 provides inherent self-locking — the output shaft will not back-drive under static load when the motor is off. This eliminates the need for a separate electromagnetic brake in many vertical-load or hold-in-place applications. Note that self-locking should not be relied upon as the sole safety mechanism in life-safety-critical systems; always consult relevant machinery safety standards (EN ISO 13849) for your application.
What output shaft configurations are available for the EP-SSGM30?
Four output configurations are offered: Type A (single solid output shaft, standard orientation), Type B (single solid output shaft, alternate side), Type D (protective end cover for shaft-free installations or cover-only use), and Type E (torque arm bracket for reactive torque management in floating-motor installations). Custom shaft diameters and keyway dimensions are available on request for OEM integration projects.
How does the EP-SSGM30 compare to standard painted cast-iron worm reducers?
Unlike painted cast-iron alternatives, the EP-SSGM30 housing will not corrode, chip, or contaminate product streams when exposed to cleaning chemicals, moisture, or food acids. The fully machined exterior requires no painting or powder coating maintenance. Long-term total cost of ownership is lower due to elimination of repainting cycles and reduced replacement frequency in harsh environments. The 304 SS construction also offers significantly better corrosion resistance than aluminum alloy housings in chlorinated or acidic wash conditions.
⭐ Customer Reviews

“We switched our chicken portioning conveyor drives from painted cast-iron units to the EP-SSGM30 and the difference in maintenance downtime is remarkable. No more rust patches after steam cleaning. The compact size fits perfectly into our existing machine frame without any modification. Highly recommended for any food-grade line.”
Dieter Hofmann — Packaging Machinery Integrator 🇩🇪
Germany 🇩🇪 ★★★★☆ 4.5
“Installed twelve EP-SSGM30 units on our pharmaceutical blister pack conveyor indexing system. The low noise level was immediately noticeable — our cleanroom noise budget was easily met. Dimensional accuracy is excellent and IEC flange fit was perfect first time. Would have given 5 stars if documentation came in German too.”
Carlos Mendez — Irrigation Systems Engineer 🇲🇽
Mexico 🇲🇽 ★★★★★ 5.0
“Our water treatment valve actuator project needed a corrosion-proof reducer that could handle constant moisture exposure. The EP-SSGM30 has been operating in our outdoor chlorinated-water pump station for over a year with zero corrosion issues. The self-locking at 40:1 ratio means our gate valves hold position reliably without a solenoid brake.”
