U604ZZ U-Groove Bearing (ID = 4mm, OD = 13mm, W = 4mm) (2 Pack)

The U604ZZ U-groove bearings are designed for smooth, guided motion along round rods, cables, or V-slot rails. Featuring a precision-machined U-shaped groove and double metal shields (ZZ), these bearings offer excellent dust protection and consistent, low-friction rotation. Ideal for linear motion systems in robotics, 3D printers, and sliding mechanisms, the 4mm bore makes them a great fit for small shafts or axles.
