Product Overview of Flexible Claw Coupling

The star coupling is a high-performance elastic coupling, specially designed for connecting two coaxial transmission shaft systems. It features compensation for the relative offset of the two shafts, shock absorption and vibration reduction, as well as wear resistance. Its core is composed of two cast steel or forged steel half couplings and polyurethane/engineering plastic elastomers. It absorbs vibration and displacement through elastic deformation and is suitable for high-precision and high-stability transmission scenarios.


Core Advantage of Flexible Claw Coupling

1.Dynamic compensation capacity ‌

The elastomer automatically compensates for radial, axial and angular deviations, adapting to displacement changes under complex working conditions and reducing equipment wear.
The unique convex claw design avoids stress concentration and ensures the stability of long-term operation.

2.High torque rigidity & Compact structure ‌

It has a wide torque transmission range (20-35,000 N·M), and its load-bearing capacity is superior to that of other couplings of the same size.
Compact in size and with low moment of inertia, it is suitable for space-constrained equipment (such as machine tools and automated production lines).

3.Wear-resistant & long service life ‌

The elastomer is made of high fatigue-resistant polyurethane (TPU), which is oil-resistant, resistant to high and low temperatures (-35°C to +100°C), and has a compression set rate as low as 15%.
The lubricating design is free, with a long maintenance cycle and reduced usage costs.

4.Satety protection

An optional dust-proof housing is available to prevent the wear of the elastic body caused by centrifugal force during high-speed operation and enhance safety.
