JIE JRESK Stainless Steel Helical-Bevel Gearmotor

Overview

The JIE JRESK is the right-angle helical-bevel version of JIE’s JRES stainless steel gearmotor range. It brings the hygienic construction of the family — a stainless cast housing designed to EHEDG guidelines, SS304 exterior parts and a stainless motor — to applications where the motor has to sit at 90 degrees to the driven shaft. JIE lists the JIE JRESK in sizes 37 to 67 with ratios from 3.98 to 145.14, motor power from 0.18 kW to 5.5 kW and output torque from 12 N·m to 910 N·m, the highest torque in the JRES family.

Seven Star LLC supplies the JIE JRESK to processing plants, utilities and marine users in Oman and the GCC, with engineering support in Muscat. Right-angle stainless drives are often fitted straight onto a conveyor or screw shaft, so we confirm shaft diameter, hollow-shaft or flange arrangement and torque support with the customer before quoting.

Operating Principle

A helical-bevel gearmotor combines helical stages, which give quiet and efficient speed reduction on parallel shafts, with a bevel gear pair that turns the drive through a right angle. In the JIE JRESK the motor drives a helical input stage, the bevel set redirects the power by 90 degrees, and a final stage delivers the reduced speed at the output. Both helical and bevel gears transmit power by rolling contact, so the efficiency stays high across the ratio band, unlike a worm gear where sliding friction turns a large part of the input into heat.

That efficiency matters in hygienic service because a stainless gearmotor cannot rely on painted cooling fins and is often washed with hot water and chemicals. A cooler-running drive keeps oil life and seal life longer. The right-angle layout also lets the motor run along the machine instead of projecting out into a walkway, which matters on crowded food lines and on deck machinery. JIE highlights low noise, freedom from oil leakage and maintenance-free operation for the JRES family.

Engineering Design of the JIE JRESK

The JRES catalogue defines the JIE JRESK with a model code covering the mounting type and the motor. Mounting options are foot mounting, flange mounting, hollow-shaft mounting and hollow shaft with flange. The code then specifies the stainless motor size (for example S890), the pole number and motor power, the gear ratio, the axis direction of the output and the 0 or 180 degree position of the installation. The hollow-shaft forms are particularly useful on stainless conveyors and screw feeders, because the gearmotor can slide directly onto the driven shaft without a separate coupling to clean.

All external parts are stainless steel 304, and the gear housing surface can be ordered machined, polished or as-cast. JIE states the family meets IP69K for food industry washdown. As with the inline JRESR, sizing follows the service factor method in the JIE catalogue, where the driven machine’s torque is multiplied by machine, prime-mover and starting factors and compared with the rated torque of the JIE JRESK for the chosen ratio.

Key Features

These points set the JIE JRESK apart for right-angle hygienic drives.

• A helical-bevel gear train turns the drive through 90 degrees with rolling-contact efficiency.
• Output torque reaches 910 N·m, the top of the JRES stainless range.
• Sizes 37 to 67 cover ratios from 3.98 to 145.14 and motor power from 0.18 kW to 5.5 kW.
• Foot, flange, hollow-shaft and hollow-shaft-with-flange mounting are all catalogued.
• A cast stainless housing follows EHEDG hygienic design guidelines, with SS304 used externally.
• JIE states the range meets IP69K for washdown in the food industry.
• Machined, polished or as-cast surface finishes can be chosen per area.
• A compact right-angle profile keeps the motor out of walkways and cleaning paths.

Industrial Applications

Within food and beverage plants in Oman, the JIE JRESK is a fit for shaft-mounted conveyor drives, screw conveyors, augers, mixers and tumblers where the drive must be cleaned daily. Dairy, bakery, meat and poultry, seafood and bottled water facilities in Muscat, Sohar, Nizwa and Salalah all run equipment of this type. Pharmaceutical and personal care producers use the same drives on mixing vessels and packaging lines where a painted gearmotor would not be accepted.

Outside the food sector, the right-angle stainless JIE JRESK suits chemical dosing skids and filter equipment in desalination and water treatment plants, deck and handling equipment on vessels, and outdoor drives near the coast where salt spray attacks painted steel. Seven Star LLC supports these users as a trusted supplier with engineering support in Muscat. In dry areas where stainless construction is not needed, the painted JIE JRT K series helical-bevel gearmotor offers higher power ratings.

How to Order

Send Seven Star LLC the required output torque and speed, the shaft diameter and preferred mounting (foot, flange or hollow shaft), the supply voltage and the cleaning regime, and our Muscat team will prepare a JIE JRESK quotation. We confirm the selection against the JIE service factor tables, check availability and delivery to sites in Oman and the GCC, and include the JRES catalogue extract. For painted drives elsewhere in the plant see the JIE JRT S series helical-worm gearmotor and the JIE JRT R series inline gearmotor.
