Frequently Asked Questions

Q: What is an open-style shaft collar locking ring used for?

A: An open-style (split) shaft collar locking ring is used to fix, limit, or stop components at a precise position along a shaft or rod. It prevents axial movement of bearings, pulleys, sprockets, or other mounted parts. The split design means you can install or remove it quickly without disassembling the entire shaft assembly.

Q: What diameter sizes are available for this shaft collar?

A: This KANDE BEARINGS shaft collar is available in a wide range of bore diameters from 6 mm up to 60 mm, making it compatible with most standard shaft and optical axis sizes used in CNC machines, 3D printers, conveyor systems, and industrial equipment.

Q: Is 304 stainless steel suitable for outdoor or high-humidity environments?

A: Yes. 304 stainless steel offers excellent corrosion and rust resistance, making this shaft collar locking ring well-suited for use in damp, humid, or light outdoor environments. It maintains its strength and finish over extended periods of use in demanding mechanical applications.

Q: Will the open-style collar damage my shaft surface when tightened?

A: When properly torqued, the set-screw on the collar clamps evenly around the shaft with sufficient grip to prevent movement without causing damage. For very sensitive or polished shaft surfaces, placing a small protective shim between the set-screw tip and shaft is recommended.
