CR 50 Type E Elastomeric Flexible Coupling – Polyurethane Element PU Pad Spider, 30mm Bore, OEM ROTEX Replacement

Factory Direct | Elastomeric Jaw / Spider Structure | 30 mm Bore | 2000 N·m | 3000 RPM | ROTEX Substitute | OEM Supported | 1-Year Warranty

Product Overview

The CR 50 Type E Elastomeric Flexible Coupling is a high‑performance jaw / spider coupling designed as a direct substitute for ROTEX® style couplings. It features a polyurethane (PU) elastic element / PU pad spider, a 30 mm bore, and delivers a rated torque of 2000 N·m with a maximum speed of 3000 RPM.

This elastomeric flexible coupling is widely used in the construction industry and other general industrial applications where reliable torque transmission, vibration damping, and misalignment compensation are required. The PU spider absorbs shock and vibration, compensates for axial, radial, and angular misalignment, and protects connected equipment from wear and impact.

With a standard jaw / spider structure, flexible operation, and OEM customization support, the CR 50 Type E coupling is an ideal replacement for original ROTEX couplings in construction machinery, manufacturing plants, and machinery repair shops.
