EP-SSRV075 — Stainless Steel Worm Gear Reducer Overview

High-torque hygienic drive applications — packaging line drives, heavy-duty food conveyors, chemical reactor agitators — that require IEC 80 or 100/112 frame motors demand a stainless worm reducer large enough to handle 0.75–1.5 kW continuous input without thermal limitation. The EP-SSRV075 Stainless Steel Worm Gear Reducer is the largest-flange model in the SSRV range to share the NMRV-series dimensional family before stepping up to size 90, making it the bridge unit between mid-range and heavy-duty stainless gearboxes. Its 28 mm Ø304 stainless output shaft and acceptance of 100/112 IEC motor flanges distinguish the SSRV075 from the smaller SSRV040–063 models and position it as the standard selection for agitators, slow bottle-rinse carousels, and heavy washing-machine drives across the food and beverage sector.

Core Features & Benefits

100/112 IEC Frame Compatibility — Widest Flange Range in Size 75

The SSRV075 uniquely accepts 100/112B5 and 100/112B14 adapters (M=180 mm, P=215/250 mm) alongside 71–90 frame adapters, covering a power range from 0.37 kW to 1.5 kW within one housing size.

Ø28 mm 304 Stainless Output Shaft — Higher Radial Load Capacity

The step-up to Ø28 mm (from Ø25 mm in SSRV050/063) significantly increases the permissible radial overhang load, enabling direct sprocket and timing-belt pulley mounting without an outboard bearing.

200 mm Torque Arm for Heavy Shaft-Mount Loads

The SSRV075’s torque arm (K1=200 mm, G=25 mm) is dimensioned for the higher reaction torques of 1.5 kW applications, providing a robust cantilever mount for shaft-mounted conveyor drives.

Output Flange Option — 165 mm PCD / 14 Bolts

The SSRV075..F flanged output (KA=111 mm, KM=165 mm, KO=14 bolts) supports direct flange-coupling to conveyor shafts and agitator vessels, eliminating shaft alignment and coupling maintenance.

Self-Locking Ratios (30:1+) — Static Load Holding Without Brake

At ratios ≥ 30:1, the worm lead angle provides inherent back-drive prevention, eliminating the cost and complexity of motorised brakes on inclined conveyors and vertical agitators.

Industry Applications & Typical Use Cases

🛒

Heavy-Duty Washing Machine Drives

Industrial dishwashers and bottle-washing machines in beverage plants run continuous three-shift cycles with hot-water and caustic wash. The SSRV075’s 304 housing and Ø28 mm stainless shaft withstand this regime without surface deterioration.

🍺

Brewing & Winery Equipment

Slow-speed mash agitators and must conveyors in breweries and wineries need torque-dense drives that resist acetic acid and SO₂ environments. The SSRV075 at ratio 40:1 or 60:1 delivers the right speed range for these applications.

📋

Pharmaceutical Tablet Coating

Pan-coater drives in pharmaceutical manufacturing require quiet, smooth speed control and hygienic construction. The SSRV075’s < 72 dB(A) noise level and GMP-compatible finish make it a validated drive choice.

🐈

Pet Food Processing

Auger feeders and rotary-drum dryers in pet-food plants run in high-fat, high-temperature environments. The synthetic oil fill and stainless construction of the SSRV075 maintain performance in these conditions.

Water & Wastewater Slow Drives

Sludge scrapers, slow mixers, and rake mechanisms in wastewater treatment require corrosion-resistant drives at ratios of 40–80:1. The SSRV075 covers this speed range with a single housing size.

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-SSRV075. 5. Specify accessories — DS/SS shaft, torque arm, or ..F flange option as needed.

❓ Frequently Asked Questions

▼ What is the rated input power for the EP-SSRV075?
The EP-SSRV075 accepts up to approximately 1.5 kW continuous input (S1 duty) when fitted with a 100/112 IEC motor flange. Actual power rating depends on ratio: efficiency is highest at low ratios (7.5–15:1) and decreases at high ratios (80–100:1). Use the selection table for S1 thermal check at your specific operating point.
▼ Does the SSRV075 require a different oil fill volume than the SSRV063?
Yes. The SSRV075 housing has a larger oil sump. Oil volume is approximately 0.25–0.35 L for horizontal mounting, increasing to ~0.4 L for vertical output-shaft-up orientation. Always fill to the oil-level indicator, not to a fixed volume, as orientation-dependent correct fill differs.
▼ Can the SSRV075 be mounted with the output shaft pointing vertically upward?
Yes, all four standard mounting positions are supported (horizontal, vertical-up, vertical-down, wall). For vertical-up mounting with the output shaft up (M6 position), ensure the oil-level plug is re-positioned to the new top face if the housing has multiple ports.
▼ Is it possible to add an encoder to the SSRV075 for closed-loop speed control?
An encoder can be fitted to the input shaft of the motor rather than directly to the SSRV075. For output-shaft encoding, a through-hollow or solid-shaft encoder bracket can be fabricated — contact our custom accessories team with your encoder make and model for a bracket quotation.
▼ What is the difference between DS and SS output shaft types for the SSRV075?
DS (Double Shaft) provides output shaft extension on both sides of the housing for dual-load or encoder attachment. SS (Single Shaft) provides output on one side only — the standard configuration. Shaft diameter is Ø28 mm for both variants; overall L and L1 dimensions differ. Refer to the SSRV output-shaft dimension table.
▼ How do I select the correct ratio for a bottling conveyor running at 12 rpm?
Assuming a standard 4-pole, 50 Hz motor (1400 rpm): required ratio = 1400 / 12 ≈ 116:1. The nearest catalogue ratio is 100:1 (giving 14 rpm) or, for 12 rpm exactly, use a VFD to trim motor speed. Alternatively, cascade two SSRV units for very low output speeds.

⭐ Customer Reviews

★★★★★

“Retrofitted SSRV075 units onto our bottle-rinse carousel drives running a 100/112 motor. Eighteen months of caustic and acid CIP — zero issues. The 28 mm stainless shaft handles the belt tension loads we couldn’t achieve with the 25 mm SSRV063.”

★★★★★

“Running on our mash agitator at ratio 40:1 in a stainless-hygienic plant. The 100/112 flange option gave us direct motor integration. Surface quality passed our internal hygiene audit to EHEDG standards. Very impressed with the build quality.”

★★★★☆

“Installed on a shrimp-processing conveyor. The salt and enzyme environment was destroying our aluminium gearboxes every 8 months. The SSRV075 has now run 15 months without any visible corrosion. Only improvement needed: clearer English installation markings on the housing.”
