GQZ 6207-2ZC3 Single Row Deep Groove Ball Bearing 35mm Bore Double Steel Shield C3 Extra Clearance Industrial Rolling Bearing

The 6207-2ZC3 single row deep groove ball bearing adopts double-sided non-contact steel dust shields and C3 expanded internal clearance. It compensates thermal expansion and shaft deformation under high temperature and vibration, while blocking fine dust particles effectively.

It is widely used in industrial motors, water pumps, conveyor lines and power tools with fluctuating loads and elevated working temperature.

• C3 extra clearance offsets shaft thermal expansion and minor deformation during operation
• Dual 2Z steel shields block dry dust without increasing rotation friction loss
• Deep raceway bears radial load and light bidirectional axial load simultaneously
• Low friction torque supports stable, low-noise continuous medium-high speed running
• Custom options: 2RS rubber seals, high-temperature grease, OEM laser marking

This bearing is widely used in:

• Three-phase drive motors, generator auxiliary rotary parts
• Centrifugal water pumps, industrial fans and ventilation blowers
• Automated conveying equipment, textile and packaging machinery
• Small gearboxes, power tools and general engineering transmission assemblies

• 25+ years experience in industrial standard bearing manufacturing
• Exported to 50+ countries worldwide
• Rich experience in OEM & custom general machinery bearing projects
• Strict ISO standard dimensional & clearance inspection before shipment
• Fast response within 24 hours
• Stable bulk supply for machinery aftermarket distributors

• Raw material hardness inspection for GCr15 bearing steel
• Precision grinding & superfinishing machining for raceway and rolling balls
• Heat treatment metallurgy and hardness control
• C3 clearance testing, dust shielding & rotation smoothness testing
• Final dimensional and appearance inspection before delivery
