Beskrivning

EP-SSRV050 — Stainless Steel Worm Gear Reducer Overview

When process engineers specify a worm reducer for wet or corrosive environments and need proven compatibility with the broadest range of IEC 63–80 frame motors, the EP-SSRV050 fills the gap between compact fractional-horsepower units and heavy-duty industrial sizes. This mid-range, size-50 stainless steel worm gear reducer features a 304 precision-cast housing with electrolytic polish, a Ø25 mm 304 stainless output shaft, and full NMRV050 dimensional compatibility. Across the SSRV series, the SSRV050 is the first model to accommodate 80B5/B14 motor flanges — expanding the power range to 0.37 kW — making it the workhorse choice for food-grade conveyor lines, dairy processing equipment, and chemical dosing systems where hygiene and torque density must coexist.

Core Features & Benefits

Ø25 mm 304 Stainless Output Shaft — No Dissimilar-Metal Contact

The standard output shaft is precision-ground 304 stainless steel, eliminating the galvanic corrosion risk that arises when carbon-steel shafts mate with stainless housings in wet environments.

Six Flange Options (63–80 IEC) — Broadest Motor Compatibility in Size 50

Accepting 80B5, 80B14, 71B5, 71B14, 63B5, and 63B14 PAM-IEC flanges, the SSRV050 covers 0.12–0.37 kW motor range without adaptor plates, reducing BOM complexity for OEM builders.

Fully Synthetic Worm Oil — Extended Service Life

Factory-filled with H1 food-compatible fully synthetic ISO VG 150 oil, the SSRV050 achieves 2,000-hour service intervals versus 500 hours for mineral-oil fills, reducing planned-maintenance frequency.

Electropolished 304 Housing — Ra ≤ 0.8 µm

The electrolytic polishing process removes surface iron, raises chromium oxide passivation depth, and achieves Ra ≤ 0.8 µm — exceeding 3-A Sanitary Standard 78-03 surface requirements.

304 Torque-Arm Accessory for Shaft-Mount Configurations

The optional 304 stainless torque arm (K1=100 mm, G=14 mm) enables flange-output or shaft-mount installations where the reducer is cantilever-supported, maintaining full stainless material consistency.

Industry Applications & Typical Use Cases

🎂

Dairy & Beverage Processing

CIP-washdown lines in dairy plants cycle hot caustic and acid multiple times per day. The SSRV050’s 304 housing and synthetic oil withstand this chemical regime while maintaining EHEDG-consistent surface quality.

👣

Chemical Dosing & Metering

Peristaltic pump drives and metering screw conveyors in chemical plants rely on the SSRV050’s corrosion resistance in chlorinated water and mild acid atmospheres — without the mass penalty of heavy-duty cast-iron alternatives.

🍳

Food Conveyor Lines

Horizontal belt conveyors and bucket elevators in meat and poultry plants specify the SSRV050 for its IP55 sealing, washdown-safe surfaces, and wide speed-ratio range (7.5–100:1) covering both slow indexing and continuous feed.

Water Treatment Equipment

Slow-speed paddle mixers and sludge scrapers in water-treatment facilities benefit from the SSRV050’s corrosion tolerance in chlorinated environments and its multi-position mounting flexibility.

Packaging Machinery OEM

OEM machine builders standardise on the SSRV050 because its NMRV050-compatible bolt pattern means zero tooling changes when upgrading to stainless for export markets with strict hygienic-design mandates.

Selection Guide, FAQ & Customer Reviews

How to Select the Right SSRV Model

1. Determine required output torque (Nm) from your load and duty cycle. 2. Calculate required ratio = motor speed (rpm) ÷ required output speed (rpm). 3. Check the selection table — locate the row matching your motor power and ratio; confirm the listed radial force (fs) does not exceed your shaft load. 4. Verify motor flange — match your motor frame (56–112) to the available PAM-IEC flange options for EP-SSRV050. 5. Specify accessories — DS/SS shaft, torque arm, or ..F flange option as needed.

❓ Frequently Asked Questions

▼ What is the maximum output torque of the EP-SSRV050?
At ratio 100:1 with an 80B5 (0.37 kW) motor, the EP-SSRV050 delivers approximately 160–210 Nm depending on efficiency at the selected ratio. For precise torque values at your specific duty cycle and ratio, refer to the model selection table on Page 28 of the catalogue or contact our applications team.
▼ Is the SSRV050 suitable for vertical shaft-up and shaft-down installations?
Yes. The oil bath is sized for all four standard mounting positions (horizontal, vertical-up, vertical-down, wall). No re-filling is required when changing orientation between these positions. For continuous vertical shaft-down operation, verify the oil level port access before installation.
▼ Can I source a matched 304 stainless motor to pair with the SSRV050?
Yes. Ever-power offers a range of stainless steel single-phase and three-phase IEC motors in 63–80 frames that mate directly with the SSRV050 input flange, providing a fully stainless motor-gearbox assembly for the most demanding hygienic applications.
▼ What cleaning chemicals are compatible with the SSRV050 seals?
Standard Viton lip seals are compatible with dilute NaOH (≤5%), phosphoric acid (≤10%), hydrogen peroxide (≤35%), and most food-grade sanitisers. For aggressive solvents (MEK, acetone) or concentrated acids/alkalis, request FKM or PTFE seal upgrades.
▼ How does the SSRV050 compare with an aluminium NMRV050 in a food plant?
Aluminium NMRV050s are approximately 30% lighter but are susceptible to pitting corrosion in chloride-rich CIP environments, and anodised coatings can be stripped by alkaline cleaners. The SSRV050 stainless housing maintains its surface integrity through 50,000+ CIP cycles without refinishing.
▼ Is the EP-SSRV050 CE marked?
Yes. The EP-SSRV050 carries CE marking under the EU Machinery Directive 2006/42/EC and is manufactured under an ISO 9001-certified quality management system. Declaration of Conformity documentation is available on request for machine CE-file compilation.

⭐ Customer Reviews

★★★★★

“Running on our yoghurt filling lines — three shifts, seven days. After 18 months in a caustic CIP environment, the housings look as good as the day we installed them. The NMRV bolt pattern made the upgrade seamless. Excellent product.”

★★★★★

“Specified SSRV050 for a mozzarella-brine conveyor. The full stainless construction passed our internal hygiene audit first time. Output torque has been consistent over 12 months of continuous operation.”

Luisa Ferrari — Impianti Alimentari Srl

★★★★☆

“We use SSRV050 on our kimchi-line dosing conveyors. The corrosive brine environment destroys standard units in months — the stainless SSRV series has now run a full production year without any surface degradation.”
