Frequently Asked Questions

Q: What shaft diameter are these LM8UU linear bearings compatible with?

A: The Kande Bearings LM8UU linear bearings are designed for use with 8mm diameter smooth linear shafts or rods. They have an inner diameter of 8mm, outer diameter of 15mm, and a length of 24mm — the standard LM8UU specification used in most 3D printers and CNC machines.

Q: Are these bearings pre-lubricated?

A: Yes, LM8UU linear bearings from Kande Bearings come pre-lubricated with grease from the factory. For optimal longevity in high-use or dusty environments, periodic re-lubrication with a suitable bearing grease is recommended.

Q: How many bearings are included in this listing?

A: This listing includes 10 pieces of the LM8UU linear bearing (8×15×24mm), giving you plenty to complete a full 3D printer build or stock up for future maintenance and repair needs.

Q: Can I use these in my 3D printer?

A: Absolutely. The LM8UU is the most widely used linear bearing in FDM 3D printers (such as Prusa, Anet, Ender-style, and many others). These Kande Bearings units meet the standard LM8UU dimensions and are a direct drop-in replacement or upgrade for most machines using 8mm linear rods.
