6315-2RS1/C3 Single Row Deep Groove Ball Bearing Double Contact Rubber Seal C3 Clearance 75x160x37mm Motor Equipment

The 6315-2RS1/C3 single row deep groove ball bearing adopts double contact 2RS1 rubber seal and C3 enlarged internal clearance, designed for heavy-load, high-temperature and dusty industrial equipment. It bears bidirectional radial and light axial load, effectively avoids thermal expansion jamming under long-hour continuous operation.

It is widely used in large industrial fans, water pumps, medium-large motors and construction machinery where dust, water splash and high working temperature exist.

• C3 enlarged clearance reserves expansion space, prevents bearing locking caused by high-temperature thermal expansion
• Double lip 2RS1 contact rubber seal provides excellent dustproof, mud-proof and splash-proof performance
• Large steel ball layout delivers strong radial load capacity, stable operation under medium-heavy continuous load
• Superfinished inner and outer raceway reduces vibration and running noise for long-time stable rotation
• Heat-treated high hardness bearing steel improves wear resistance and extends service life in harsh workshop conditions
• Multiple optional variants: open type, ZZ metal shield, stainless steel anti-rust version, standard CN clearance
• Pre-filled long-life industrial grease reduces frequent on-site lubrication maintenance work

This C3 sealed heavy-duty bearing is widely used in:

• Large industrial cooling fans, medium & large three-phase drive motors
• Industrial water pumps, hydraulic equipment and heavy speed reducers
• Light construction machinery, mining small conveying roller assemblies
• Agricultural heavy power equipment and packaging large transmission machinery
