Precision Quality

Used these for a custom 3D printer build. The tolerances are tight and the flanges help with alignment. Highly recommend for makers.

Solid Bearings for General Use

They are a bit stiff out of the box but loosened up after some run time. Good for low load applications as described.

Good Variety Pack

Quality seems solid for the price. I wished there were more of the 5mm size in the pack, but overall happy with the purchase.

5 FAQ

Q: What is the exact tolerance on the 5mm bore?

A: The tolerance follows standard ABEC-5 specifications. Please refer to the technical diagram in the product images for exact microns.

Q: Is there a warranty included?

A: Yes, all our bearings come with a 30-day return policy if they are defective or do not meet specifications.

Q: Are these bearings made of stainless steel?

A: No, these are made of Chrome Steel (GCr15) for durability and hardness. They are not corrosion-resistant stainless steel.

Q: Do you sell replacement grease for these?

A: We recommend standard lithium-based bearing grease for re-lubrication if needed in the future.

Q: Can I clean these bearings with solvent?

A: We do not recommend cleaning them as it will remove the pre-applied lubrication. They are ready to use out of the package.
