10x NSK Japan 693ZZ & R-830ZZ Miniature Bearings – Metal Shielded, 3x8x4mm

Got a project that needs some tiny, smooth-spinning parts?

This lot gives you ten precision miniature bearings, sourced from NSK Japan quality.

You're getting a mix of 693ZZ and R-830ZZ models, all with metal shields to keep dust and grit out.

They measure exactly 3mm inside, 8mm outside, and are 4mm wide—the perfect size for all sorts of hobbies, from 3D printer rollers to RC car wheels or small electric motors.

They come in their original packaging, brand new and ready to roll.

If you're tinkering or repairing, having these on hand is a total lifesaver.
