6305-2Z/C3GJN Single Row Deep Groove Ball Bearing Double ZZ Metal Shield C3 Clearance 25x62x17mm Mini Motor Equipment

The 6304-2RSH/C3 single row deep groove ball bearing adopts double-sided 2RSH low-friction contact rubber seal and C3 enlarged internal clearance. It can bear radial load and slight bidirectional axial load, designed for small motors, water pumps and ventilation equipment running under high temperature, dusty and splash environments.

• C3 enlarged clearance reserves thermal expansion space to avoid bearing seizure under continuous high-speed high-temperature operation
• 2RSH optimized low-friction double lip rubber seal balances low rotation torque and excellent dust & splash resistance
• Pre-filled long-life multi-purpose grease, stable lubrication without frequent re-greasing maintenance
• Superfinished inner and outer raceway reduces vibration and running noise for miniature rotary equipment
• High hardness quenched bearing steel delivers good wear resistance under medium continuous load
• Multiple optional types: open bearing, ZZ metal shield, standard CN clearance, stainless steel anti-rust version
• Standard metric universal size, fully interchangeable with general aftermarket replacement bearings
