Frequently Asked Questions

Q: What bore sizes does the Kande XL7 D118L160 flexible jaw coupler support?

A: The Kande XL7 D118L160 shaft coupler is available in bore sizes of 20mm, 30mm, 40mm, 45mm, 50mm, 60mm, and 70mm, covering a wide range of CNC motor and ballscrew shaft diameters for flexible integration into most standard machine configurations.

Q: What is a jaw/spider (plum) flexible coupling and how does it work?

A: A jaw/spider coupling consists of two steel hubs and a flexible elastomeric spider insert (also called a plum or star insert) that fits between the jaws of each hub. This design transmits torque while absorbing vibration and accommodating minor angular, parallel, and axial shaft misalignment — making it ideal for CNC routers, servo motors, and ballscrew drive assemblies.

Q: Is this coupling suitable for both servo and stepper motor CNC applications?

A: Yes. The Kande XL7 D118L160 clamp-type flexible coupling is designed to connect servo motors, stepper motors, and ballscrews in CNC systems. The clamp design provides a secure, tool-tightened grip that minimizes backlash, ensuring precise motion transfer critical for CNC accuracy.

Q: What material is the Kande XL7 D118L160 shaft coupler made from?

A: The coupling hubs are manufactured from high-grade steel, providing excellent strength, durability, and torque capacity suitable for demanding industrial and CNC machining environments.
