Shaft Coupling Description
RX 75/90-98 (ER75090) - Elastic Spider (98 Shore A, Red, Polyurethane) is a part designed for RX shaft couplings.
RX are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a polyurethane element. They transmit torque through pressure-stressed elastic star-shaped buffer which absorbs shock and torsional vibration. This element is oil resistant and electrically conductive.
Shaft Coupling Construction
- Hubs
- Elastic spider
Shaft Coupling Fields of Use
RX flexible couplings are designed for the highest requirements in a wide range of industries, especially for compressors, pumps, conveyors, construction machinery and many other machines. They are available in two-piece aluminum, cast iron and steel design.
Shaft Coupling Characteristics
- High-quality spider design
- Handles the most demanding applications
- Operating temperatures from −40 °C to +90 °C, allowing for short peaks up to 120 °C
- Wide range of sizes. Allows for different bore diameters
- Simple assembly without the need to modify the bore (applies to versions with Taper Lock bushings)
- No backlash. Easy assembly. No maintenance.
