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.

Perfect for my RC Car Upgrade

These bearings fit perfectly into my hobby grade RC car. The smoothness is noticeable compared to the stock parts. Great value for the assortment.

Fast Shipping and Well Organized

Arrived quickly and the storage box keeps everything sorted. The bearings spin freely without any grit. Will buy again.

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.
