GQZ 6930 C3 Thin Section Deep Groove Ball Bearing 150×210×28mm For Precision Automation Equipment

6930 C3 belongs to thin-wall 69 series single row deep groove ball bearing. C3 represents larger-than-standard radial internal clearance. Ultra-slim radial cross-section effectively reduces overall structural size. It can bear radial load and minor bidirectional axial load simultaneously. Stable rotation with low friction characteristic. Widely applied in precision automation equipment, textile machinery, packaging machinery, robot auxiliary joints and light-duty rotating assemblies with limited installation space.

Formal quotation will be sent within 24 hours upon your inquiry.

Complete dimension drawings and load data available on request.

1. Thin wall slim design, greatly save radial installation space and lighten equipment weight
2. C3 extra clearance reserves allowance for thermal expansion during long-time continuous operation
3. Capable of bearing radial load plus small bidirectional axial load
4. Low vibration, low noise and smooth operation under medium rotating speed
5. Standard interchangeable dimension, multiple sealing configurations available for different environments
6. Customizable options: OEM laser marking, anti-rust treatment, special grease matching Optimize structural layout for compact precision mechanical rotating units.
