EP-SSVF50 — Stainless Steel VF Worm Gear Reducer Overview

Mid-range food and pharmaceutical drives that specify a face-mount hollow-flange worm reducer with 0.12–0.37 kW input power and compatibility with 63–80 IEC motor frames need a product that combines the VF body’s installation advantages with full 304 stainless corrosion resistance. The EP-SSVF50 Stainless Steel VF Worm Gear Reducer fills this specification with a size-50 304 precision-cast, electropolished housing, Ø25 mm 304 stainless output shaft, and six PAM-IEC flange options covering 63–80 frame motors. In the SSVF series, the SSVF50 is the first model to offer Ø25 mm output shaft geometry — a significant step-up in radial load capacity from the 18 mm shaft of the SSVF40 — and adds 80B5/B14 motor compatibility, unlocking 0.18–0.37 kW applications on dairy lines, bottling machines, and hygienic chemical pump drives.

Core Features & Benefits

Ø25 mm 304 SS Output Shaft — 40% Higher Radial Load than SSVF40

The step from Ø18 mm (SSVF40) to Ø25 mm output shaft in the SSVF50 increases the permissible radial overhang load by approximately 40%, enabling direct sprocket or pulley mounting without an outboard support bearing on most light industrial applications.

Six PAM-IEC Flange Options (63–80 Frame) — Broadest Power Coverage

Accepting 80B5, 80B14, 71B5, 71B14, 63B5, and 63B14 adapters in the size-50 housing gives system integrators the widest motor compatibility in the compact-drive class, from 0.12 kW (63 frame) to 0.37 kW (80 frame) without housing changes.

Ø108 mm Input Flange Face — Direct 80B5 Motor Integration

The 134 mm overall length and Ø108 mm motor-face bore of the SSVF50 accept 80B5 motors directly, enabling a compact 0.37 kW motorised drive assembly that is 20–25% shorter in the axial direction than an equivalent RV-body (SSRV050) combination.

Output Flange KM=85 mm PCD — Standard VF50 Mating Geometry

The SSVF50..F output flange (KA=90 mm, KM=85 mm, 11 bolt positions) matches the standard VF50 output-flange mating geometry used across the industry, ensuring drop-in compatibility with existing VF50 machine designs upgrading to stainless.

Torque Arm K1=100 mm — 304 SS, Same Material as Housing

The optional 304 SS torque arm (K1=100 mm, G=14 mm, KG=38.5 mm) maintains full material consistency for shaft-mount configurations, eliminating the galvanic-corrosion risk of mixing carbon-steel accessories with a stainless housing.

Industry Applications & Typical Use Cases

🍼

Dairy Processing & Filling Lines

Yoghurt and cream filling heads, CIP-return conveyors, and slow-speed paddle agitators in dairy plants specify the SSVF50 for its corrosion resistance in lactate and caustic environments and its 0.37 kW maximum power handling.

🐉

Beverage & Juice Processing

Juice-extraction conveyor drives and bottle-rinse carousels in beverage plants select the SSVF50 for its face-mount integration, stainless wetted surfaces, and the 80B5 motor flange option enabling 0.25–0.37 kW drive configurations.

🔥

Hygienic Chemical Pump Drives

Gear-pump and centrifugal-pump drives in pharmaceutical API manufacturing and specialty-chemical plants use the SSVF50’s VF hollow-flange for direct integration onto the pump head, eliminating coupling misalignment.

🌵

Greenhouse & Hydroponic Automation

Grow-light positioning drives and nutrient-dosing pump gearboxes in commercial greenhouse operations use the SSVF50’s compact stainless construction and multi-position mounting versatility.

📏

Automated Liquid Sampling Systems

Slow-speed rotary sampling conveyors and fraction-collector drives in process-analytics and quality labs specify the SSVF50 for its precise ratio selection and repeatable, low-backlash worm gear 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-SSVF50. 4. Check VF flange compatibility — confirm your driven-machine flange accepts the SSVF50 output-flange PCD (KP=125 mm, 11 bolt holes). 5. Specify accessories — 304 SS output shaft (DS/SS), torque arm, or ..F flange option as needed.

❓ Frequently Asked Questions

▼ How does the SSVF50 compare with the SSRV050 for the same power requirement?
Both models accept 63–80 IEC motor frames and have Ø25 mm output shafts. The SSVF50 (VF body) is approximately 20 mm shorter in the axial direction and mounts face-to-face with the driven machine — no coupling needed. The SSRV050 (RV body) has a solid protruding output shaft and mounts via foot or torque arm. Choose SSVF50 when the driven machine has a VF-compatible flange face; choose SSRV050 for belt/chain or cantilever shaft-drive applications.
▼ What output shaft dimensions are available for the SSVF50?
Standard single-shaft (SS): d=25 mm, B=50 mm, B1=53.5 mm, G1=92 mm, L=153 mm, L1=199 mm, M10×27 thread end. Double-shaft (DS): shaft extends on both sides of the housing — contact us for DS dimensions. Optional 304 SS shaft is a catalogue accessory; carbon-steel shaft is the default supply.
▼ Is the SSVF50 compatible with VFD (inverter) speed control?
Yes. The worm gear drive in the SSVF50 is compatible with VFD-controlled motors. When using a VFD, maintain minimum input shaft speed above ~300 rpm to ensure adequate splash lubrication in the worm gear housing. For speeds below 300 rpm input, specify a pressure-lubrication or oil-bath-heightened version on enquiry.
▼ What is the permissible ambient operating temperature range?
The SSVF50 is rated for ambient temperatures from -20°C to +50°C with standard fully synthetic ISO VG 150 oil. For ambient temperatures above +50°C, specify ISO VG 220 oil and apply a 15–20% output torque de-rating to prevent thermal overload. For temperatures below -20°C, contact our technical team for low-temperature oil recommendations.
▼ Can two SSVF50 units be tandem-mounted for higher reduction ratios?
Yes. Two SSVF50 units in series achieve ratios of 56:1 to 10,000:1. An intermediate coupling bracket between the output shaft of the first stage and the input flange of the second stage is required. Contact our applications team for tandem-mount bracket drawings for the SSVF50.
▼ Does the SSVF50 have a hollow-bore output option (KHD or through-bore)?
The standard SSVF50 output is a hollow face-mount flange (VF design) with an output shaft inserted through the flange bore. A through-hollow-bore option (for shaft-through applications like agitator shafts) is available on request as a custom configuration — specify bore diameter and length at time of order.

⭐ Customer Reviews

★★★★★

“We run SSVF50s on our cream-filling conveyor drives in a three-shift CIP environment. The face-mount VF design gave us a significantly shorter drive train than our previous SSRV units. Eighteen months in caustic wash cycles — no corrosion, no seal failures. The 80B5 flange option was exactly what our motors needed.”

Jason Williams — Dairy Line Engineering Pty

★★★★★

“Installed on our cheese-brine conveyor agitators. The stainless VF50 design passed our internal hygiene audit to EHEDG standards at first inspection. We particularly value the pre-filled H1 food-grade oil — one less compliance step during commissioning.”

Anne-Laure Bernard — Fromagerie Industrielle SA

★★★★☆

“Using SSVF50 on juice-extractor conveyor drives. VF face-mount simplified our machine assembly considerably. Stainless construction handles our orange-acid environment that was destroying our aluminium drives. Good product — clearer thermal-rating data in English would help.”
