Frequently Asked Questions

Q: What is the difference between the LM25OP open type and a standard LM25UU closed linear bearing?

A: The LM25OP open type linear bearing features a longitudinal slot cut along its outer sleeve, whereas the standard LM25UU is a fully closed cylinder. The open slot design of the LM25OP allows easier access for lubrication, faster shaft installation, and the ability to use the bearing on shafts with minor surface imperfections. Both share the same 25 × 40 × 59mm envelope dimensions, making the LM25OP a compatible drop-in upgrade.

Q: What shaft size does the LM25OP CNC linear bushing fit?

A: The LM25OP is designed for a 25mm diameter linear guide shaft. Its outer diameter is 40mm and its length is 59mm, matching standard industry sizing for CNC, 3D printer, and automation linear motion systems.

Q: Is this linear bearing suitable for high-speed CNC applications?

A: Yes. The Kande Bearings LM25OP is constructed from hardened bearing steel with a precision ball retainer, making it well-suited for both moderate and higher-speed linear motion applications in CNC routers, laser cutters, and similar machinery. Regular lubrication is recommended to maintain optimal performance and extend service life.

Q: How many bearings are included in one order?

A: Each order includes 1 piece of the LM25OP open type linear bushing (25 × 40 × 59mm). If you require multiple units, please adjust the quantity before adding to cart.
