6313C3 Single Row Deep Groove Ball Bearing C3 Enlarged Internal Clearance 65x140x33mm High Temp Motor Heavy Industrial Equipment

The 6313C3 single row deep groove ball bearing adopts C3 enlarged internal clearance, standard dimension 65×140×33mm. 6300 series large steel ball layout provides excellent heavy radial load capacity, also bears slight bidirectional axial load. C3 extra clearance reserves sufficient expansion gap under high-speed and high-temperature operation, effectively prevent bearing jamming caused by thermal expansion. Open structure supports independent matching with metal shields or rubber seals, widely used in high-temperature motors, large fans, mining auxiliary equipment, agricultural machinery and high-speed heavy-duty transmission assemblies.

• C3 enlarged clearance design: extra internal gap to absorb thermal expansion of inner & outer rings, avoid stuck under continuous high temperature high speed
• 6300 series larger steel balls deliver much higher load capacity than 60/62 series bearings with same bore size
• Precision superfinished raceway and steel balls ensure smooth low-vibration rotation under heavy continuous load
• High-hardness quenched bearing steel improves wear resistance for dusty, high-temperature harsh working environment
• Multiple interchangeable variants: open 6313C3, dust-proof 6313C3ZZ, splash-proof sealed 6313C3-2RS
• Straight open design convenient for on-site grease refilling, extend service life for long-hour running equipment
