Frequently Asked Questions
Unlike gear couplings, the XL Spider coupling is lubrication-free, offers superior vibration damping via Polyurethane GR elastomers, and provides electrical insulation to protect bearings from shaft currents.
The coupling is designed with a preset breaking torque (≤ 150% of rated torque). In an overload event, the elastic spider breaks first, acting as a fuse to prevent catastrophic failure of the motor or reducer.
Yes. With an operating noise level below 70dB(A) and a lubrication-free design that prevents oil contamination, they are ideal for clean-room environments.
The wear-resistant and aging-resistant elastomer typically provides a service life ranging from 30,000 to 50,000 hours, depending on the load and environmental conditions.
Aluminum alloy hubs are 60% lighter than steel or cast iron, which reduces the moment of inertia and typically results in an energy saving of approximately 1.5% to 3%.
One of the key advantages of the XL series is its efficiency; replacing the elastomer typically takes only 10 minutes and does not require moving the main body of the equipment.

Precision in power transmission is the cornerstone of high-performance automation. When dealing with servo systems, CNC equipment, or 3D printing modules, the slightest rotational clearance can lead to significant positioning errors and accelerated component wear. The aluminum alloy double diaphragm coupling is engineered specifically to eliminate this backlash while compensating for critical alignment deviations. By leveraging the elastic deformation of stainless steel diaphragms, this component ensures a rigid yet flexible torque transfer that protects sensitive encoders and motors from axial and radial stress. For procurement managers and system engineers, selecting a reliable flexible coupling Factory means balancing torsional rigidity with lightweight construction.
