U625ZZ U624ZZ Steel U V Sealed Groove Ball Bearing U623ZZ U604ZZ U624ZZ Track roller bearings

This series of U/V sealed groove ball track roller bearings (including U623ZZ, U604ZZ, U624ZZ, U625ZZ) are high-precision light-load components tailored for small-scale industrial guide and transmission scenarios. They feature optional U/V groove structures to match corresponding light-load guide rails, with core dimensions for each model:

• U623ZZ: 3×10×4 mm
• U604ZZ: 4×12×4 mm
• U624ZZ: 4×13×5 mm
• U625ZZ: 5×16×5 mm

Crafted from premium GCr15 bearing steel, the bearings undergo precision raceway grinding and heat treatment, delivering low friction and stable rolling performance. Equipped with double-sided metal seals (ZZ), they effectively isolate dust and tiny contaminants in narrow installation spaces, while maintaining long-term lubrication stability (pre-filled with high-performance lithium-based grease). The compact structural design makes them ideal for small equipment with limited installation space.
