Exact dimensions
I was worried about sizing but the LMF12UU matched my specifications exactly. The flange makes mounting very easy.

Perfect for 3D printer upgrade
Upgraded my old printer with these. Much quieter than the previous bushings. Highly recommend for automation projects.

Fast shipping and well packed
Arrived quickly and were protected well against rust. The nickel plating looks durable. Will buy again.

Smooth operation for CNC build
These bearings fit perfectly on my 8mm shafts. The motion is very smooth with minimal friction. Great quality for the price.

Good quality, slight break-in
Quality seems solid. They were a bit tight at first but loosened up after some use. No issues so far.
Q: Are these bearings pre-lubricated?
A: Yes, all our linear ball bearings come pre-greased from the factory.
Q: What shaft tolerance is recommended for these bearings?
A: We recommend using shafts with h6 or g6 tolerance for optimal performance and longevity.
Q: Do you offer bulk discounts for large orders?
A: Yes, please contact our sales department directly for pricing on quantities over 50 units.
Q: What is the difference between LMF and LM series?
A: LMF series includes a round flange for easier mounting, while LM series is cylindrical without a flange.
Q: Can these handle high-speed applications?
A: They are suitable for moderate speeds. For very high-speed applications, please consult our engineering team.
