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:
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 lubriion stability (pre-filled with high-performance lithium-based grease). The compact structural design makes them ideal for small equipment with limited installation space.
Small automated assembly line guide components, electronic equipment transmission mechanisms, office automation device guide parts, toy machinery transmission systems, precision instrument auxiliary guide structures, light logistics micro-conveying systems
This series of bearings (interchangeable with bearings matching "U-series + U/V groove + corresponding size + ZZ seal" specifiions, including:

Q: What is the difference between U-groove and V-groove in this series?
A: U-groove is suitable for flat-bottomed guide rails, while V-groove matches V-shaped guide rails—both can be customized according to the equipment's guide rail structure.
Q: Can these bearings be used in high-speed scenarios?
A: They are designed for light-load, low-to-medium speed scenarios (limit speed: ~8000 r/min under grease lubriion), not recommended for high-speed rotating equipment.
Q: Is the lubriion of these bearings maintenance-free?
A: Yes, they are pre-filled with lithium-based grease and sealed with ZZ, so no additional lubriion is needed during their service life (under normal light-load conditions).
