  • Great Replacement Bicycle Pedal Bearings
Size: MR128-2RS Number of Items: 10
My bicycle pedals spin better than my highest expeditions with these bearings. I can't attest to durability but at this price point its worh the risk.

  • Smooth, precise fit for Bambu X1C AMS rollers
Size: 693-ZZ Number of Items: 10
These bearings work exactly as expected and fit perfectly snug on my Bambu X1C AMS rollers. Installation was straightforward, and all bearings in the pack were consistent in size and finish. They spin smoothly right out of the box with no grinding or play. The double-shielded design is especially useful in a 3D-printing environment, helping keep out dust and fine filament debris that can accumulate over time. After installation, the rollers move freely and evenly, with no added noise or resistance. Fit and performance matched the listed specifications. Maintenance tip: For best long-term performance, avoid over-lubricating. These bearings are pre-greased; if maintenance is needed later, a very small amount of light machine oil is sufficient. Periodic inspection and gentle cleaning will help extend service life, especially in dusty print enclosures. Overall, these are solid, well-made bearings that do what they’re designed to do. Five stars. ... show more

  • Great value compared to name branded bearings!

Same size for my Hobbyplus Arktos & Terranaut 8x8 and they are cheaper and better than the stock bushings in my RC trucks. MR128-2RS worked for me and MR63-ZZ. Great same bearings and a better value!

Bought for a 3d printed Rubber Band powered car. Bearings fit perfectly into the model and definitely better than 3d printed axel connections we’ve used previously.
