EP-SSVF30 — Stainless Steel VF Worm Gear Reducer Overview
Miniature hygienic drive stations in laboratory instruments, micro-conveyors, and small pharmaceutical packaging machines rarely justify the cost of a full size-40 reducer — yet they cannot tolerate the corrosion risk of aluminium housings in wet or sanitised environments. The EP-SSVF30 Stainless Steel VF Worm Gear Reducer bridges this gap: a size-30, 304 stainless steel, face-mount hollow-flange worm reducer designed around the VF layout used in compact right-angle drives. As the smallest model in the SSVF series, the SSVF30 targets fractional-horsepower applications (0.04–0.09 kW) with 48–56 IEC motor frames, delivering ratios from 7.5 to 100:1 in a housing width of approximately 60 mm. Its compact face-mount output flange enables tight integration into machine frames where flange-coupled reducers offer significant space advantages over foot-mounted alternatives.

Core Features & Benefits
Smallest SSVF Model — ~60 mm Face Width for Tight Machine Integration
At approximately 60 mm housing face width, the SSVF30 fits inside machine cabinets and robot arms where no larger stainless reducer can be accommodated, opening up hygienic-grade stainless drives to ultra-compact machine designs.
VF Face-Mount Flange Output — No Shaft Coupling Required
The VF hollow-flange output mounts the reducer directly onto a mating driven-machine flange face, eliminating the coupling, coupling guard, and shaft-alignment procedure required by conventional solid-shaft reducers.
304 Stainless Housing — Electrolytically Polished All Faces
All six external faces of the SSVF30 housing are precision-machined and electrolytically polished to Ra ≤ 0.8 µm, ensuring no bacteria-harbouring crevices and full compatibility with CIP and IPA wipe-down cleaning.
12-2 Tin-Bronze Worm Wheel — Silent Worm Mesh Below 65 dB(A)
The 12-2 tin-bronze wheel and hardened steel worm shaft produce a quiet, smooth mesh — particularly important in laboratory and medical environments where noise must be minimised.
48 & 56 IEC Motor Frames — Fractional-Horsepower Compatibility
The SSVF30 accepts 56B5, 56B14, 48B5, and 48B14 adapters, covering the fractional-horsepower (0.04–0.09 kW) motor range not serviced by larger SSVF models, enabling a fully stainless miniature motorised drive.
Industry Applications & Typical Use Cases
Laboratory & Analytical Instruments
Precision sample-handling robots, auto-samplers, and fraction collectors in analytical chemistry labs specify the SSVF30 for its sub-miniature envelope, corrosion-safe 304 housing, and repeatable low-speed performance.
Medical Device Manufacturing
Syringe-filling machines, pump drives, and valve actuators in medical device assembly require the smallest possible stainless gearbox footprint. The SSVF30’s face-mount flange mounts flush inside the machine frame.
Micro Dosing & Dispensing Systems
Peristaltic pump gearboxes and micro-dispenser drives in food-supplement and cosmetic manufacturing use the SSVF30 for its 7.5–100:1 ratio range and inherent self-locking at ratios ≥ 30:1.
Hygienic Sensor & Valve Actuators
Automated sampling valves and sensor-positioning drives in clean-process piping systems require corrosion-resistant gear drives. The SSVF30’s electropolished surface is compatible with CIP and SIP protocols.
Miniature Conveyor & Feeder Drives
Vibrating bowl-feeder drives and small belt conveyors in electronics assembly and pharmaceutical tablet inspection use the SSVF30 for its minimal footprint and noise-controlled worm mesh.
Selection Guide, FAQ & Customer Reviews
How to Select the Right SSVF Model
1. Define required output torque (Nm) and output speed (rpm) from your process requirements. 2. Calculate ratio = motor speed ÷ output speed. 3. Match motor frame to available PAM-IEC adapters for EP-SSVF30. 4. Check VF flange compatibility — confirm your driven-machine flange accepts the SSVF30 output-flange PCD (KP=90 mm, 8 bolt holes). 5. Specify accessories — 304 SS output shaft (DS/SS), torque arm, or ..F flange option as needed.

❓ Frequently Asked Questions
⭐ Customer Reviews
“We specified the SSVF30 inside our auto-sampler gearbox enclosure. The 60 mm face width was the only stainless option that fit. Six months of daily IPA wipe-down — zero corrosion. The smooth worm drive noise is barely detectable in our quiet lab environment.”
Dr. Emma Clarke — BioLab Instruments Pty

“Used on valve actuators in an ISO Class 5 cleanroom. Electropolished surface passed our particle-emission audit. Compact VF flange mount simplified our machine frame design significantly. Very impressed with the build quality for such a small unit.”
Klaus Weber — Reinraumtechnik GmbH
Germany 🇩🇪
“Installed on micro-dispensing pump drives in our nutraceutical line. Self-locking at ratio 40:1 eliminates the need for a separate motor brake. Good torque consistency. Would appreciate more documentation on S1 thermal limits for this size.”
