Deskripsi

EP-SSRV063 — Stainless Steel Worm Gear Reducer Overview

Mid-range industrial applications in wet and hygienic environments — think filling machines, bottling conveyors, and pharmaceutical agitators — frequently require a 25 mm output shaft with 0.18–0.75 kW input power and drop-in compatibility with 71–90 IEC motor frames. The EP-SSRV063 Stainless Steel Worm Gear Reducer addresses this specification directly. As the third and centre-of-range model in the SSRV line, the SSRV063 shares the Ø25 mm 304 stainless output shaft geometry of the SSRV050 but steps up to a larger housing capable of accepting 90B5 and 90B14 flanges — unlocking 0.55–0.75 kW motor compatibility unavailable on the smaller units. Industries from chemical mixing to seafood processing choose the SSRV063 for its balance of torque capacity and hygiene-grade construction.

Core Features & Benefits

90-Frame Motor Compatibility — Unlocks 0.55–0.75 kW Range

The SSRV063 is the entry point in the SSRV range for 90B5 and 90B14 motor flanges. This opens 0.55–0.75 kW single-phase and three-phase motors, extending the torque envelope significantly compared with the 80-frame limit of the SSRV050.

Worm Wheel: ZCuSn12-2 Tin Bronze — Corrosion-Proof Gear Material

The 12-2 tin bronze wheel resists corrosion from sulphur-bearing food aromas, brine, and mildly acidic cleaning agents. Combined with the 304 housing, all functional surfaces exposed to the internal oil environment are non-ferrous.

Six Motor Flange Adapters (71–90 IEC) — Stocked for Fast Delivery

All six standard PAM-IEC adapters (90B5, 90B14, 80B5, 80B14, 71B5, 71B14) for the SSRV063 are manufactured and stocked, enabling 48-hour dispatch on standard configurations.

IP55 Standard Protection — IPX6 Washdown Optional

Standard sealing is IP55. For high-pressure hose-down (IPX6) duty in meat and fish plants, request enhanced double-lip shaft seals and sealed vent plugs at time of order.

Output Flange (F Option) Available in 304 Stainless

The SSRV..F output flange (KA=82 mm PCD, 10 bolts, KC=6 mm) is cast and machined from 304 stainless steel as an optional accessory, supporting hollow-shaft and direct-flange-mount drive configurations.

Industry Applications & Typical Use Cases

🐑

Seafood & Meat Processing

Salt-spray and blood-acid environments in seafood and meat plants aggressively corrode aluminium drives within months. The SSRV063’s 304 housing provides the chemical passivity required for continuous washdown service.

💧

Chemical Mixing & Agitation

Slow-speed paddle agitators and ribbon blenders in batch chemical plants specify the SSRV063’s 7.5–100:1 ratio range and its self-locking characteristic at ratios ≥ 30:1 to hold static loads during mixing pauses.

🍼

Bakery & Confectionery Conveyors

Dough-piece conveyors and cooling tunnels in bakeries use the SSRV063 for its quiet worm mesh (< 72 dB(A)), wide ratio availability, and easy integration with 80B5 motors typically found in existing bakery machine frames.

Bottling & Labelling Lines

Bottle-carousel and label-applicator drives in beverages and cosmetics production choose the SSRV063 for its compact 95–146 mm housing width and NSF-compatible synthetic oil filling.

📐

Pharmaceutical Agitators & Mixers

GMP-validated mixing vessels and transfer conveyors in pharmaceutical plants rely on the SSRV063’s electropolished finish, Viton seals, and dimensional traceability to NMRV063 standards.

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-SSRV063. 5. Specify accessories — DS/SS shaft, torque arm, or ..F flange option as needed.

❓ Frequently Asked Questions

▼ What differentiates the SSRV063 from the SSRV050 dimensionally?
The SSRV063 housing is approximately 51 mm longer (173 mm vs 153 mm output-shaft length L) and 15 mm wider than the SSRV050. The output shaft remains Ø25 mm in both models. The key operational difference is motor-flange range: the SSRV063 adds 90B5/B14 compatibility, enabling up to 0.75 kW input power.
▼ Can the SSRV063 run continuously at ratio 100:1 without overheating?
At ratio 100:1, worm gear efficiency drops to approximately 50–60%. Thermal rating should be checked using the S1 (continuous duty) thermal limit in the selection table. For input power above 0.25 kW at high ratios, a cooling fan or extended heat-sink housing may be required — contact our applications team.
▼ What is the minimum output shaft speed achievable with an SSRV063?
With a standard 4-pole, 50 Hz motor (1400 rpm) and ratio 100:1, output shaft speed is approximately 14 rpm. With a 6-pole motor (940 rpm) and ratio 100:1, output drops to ~9.4 rpm. For lower speeds, cascade with a second SSRV unit or specify a variable-frequency drive.
▼ Are non-standard ratios (e.g., 45:1) available for the SSRV063?
Standard catalogue ratios are 7.5, 10, 15, 20, 25, 30, 40, 50, 60, 80, 100:1. Non-standard ratios are available as custom orders — typically ratios between 8:1 and 90:1. Please specify your required output speed, input power, and duty cycle when enquiring.
▼ Is the SSRV063 suitable for ATEX Zone 2 (Gas) environments?
The standard SSRV063 is not ATEX-certified. For Zone 2 hazardous-area applications, the gearbox must be paired with an ATEX-rated motor and the installation must comply with EN/IEC 60079. Contact our technical team for ATEX-compatible seal and lubrication recommendations.
▼ What warranty does Ever-power provide on the EP-SSRV063?
Ever-power provides a 12-month warranty from date of commissioning (not exceeding 18 months from shipment) covering manufacturing defects in materials and workmanship. Warranty is void if the unit is overloaded beyond rated input power or run without adequate lubrication.

⭐ Customer Reviews

★★★★★

“Installed 20 units on our prawn-processing conveyor lines. Twelve months of salt-water and CIP exposure and not a single corrosion mark. The 90B5 flange option gave us the motor torque we needed without oversizing to a bigger gearbox. Highly recommended.”

Craig Thompson — Seafood Processing Equipment Pty
Australia 🇦🇺

★★★★★

“The SSRV063 replaced aluminium reducers on a brine-injection conveyor. We had failures every six months with aluminium — the stainless units have now run 14 months without any sign of degradation. Very satisfied.”

Isabelle Dupont — Agroalimentaire SA
France 🇫🇷

★★★★☆

“Good torque and easy motor adaptation. The 90-frame flange option was exactly what our existing motors needed. One suggestion: include a printed oil-change interval card inside the packaging for maintenance teams.”
