L Series Elastic Jaw Coupling

Its core structure consists of two steel hubs with ‌ protruding claws and a ‌ polyurethane elastic pad ‌. During operation, the deformation of the elastic body is utilized to compensate for axial, radial and angular deviations. Its advantages lie in ‌ efficient buffering of vibration and shock loads ‌ (vibration reduction rate over 30%), ‌ maintenance-free operation ‌ (no lubrication required), and ‌ micro-deviation self-adaptive capability ‌. It is particularly suitable for medium and small power (torque range 2-400Nm) scenarios that require frequent starts and stops or have slight centering errors. Such as servo motors, air compressors, hydraulic equipment, small pumps and valves, and transmission systems for automated production lines.

1.Claw structure

Elastic buffer: Built-in polyurethane/rubber elastomer absorbs shock and vibration, protecting the equipment shaft system.

Youdaoplaceholder0 torsional load distribution: The three-jaw design evenly disperses the torque and reduces local stress.

2.Maintenance-free maintenance

There is no metal contact friction, no need to add lubricating oil, and it reduces operation and maintenance costs.

3.Modular design

The Hubs and elastomers can be replaced independently. The replacement only takes ‌10 minutes, without the need for axial movement of equipment, significantly improving maintenance efficiency.

4.High compensation capacity

radial/angular deviation compensation: Supports radial offset ≤0.38mm and angular deviation ≤1° (specific values vary by model).

5.Wide applicability

Compatible with rotating equipment such as motors, pumps, fans and compressors, covering a speed of  ≤4000 RPM‌ and a torque of ≤900 Nm‌ (taking L110 as an example).
