GQZ 2215 Double Row Self-Aligning Ball Bearing 75×130×31mm For Fans And Processing Equipment

2215 is double row self-aligning ball bearing with straight cylindrical bore. The spherical raceway of outer ring provides reliable self-aligning ability to compensate shaft deflection and housing misalignment. It can bear radial load and minor bidirectional axial load at the same time. Simple structure, low friction and stable rotation characteristics. Widely applied in ventilation fans, textile machinery, belt conveyors, agricultural equipment and various rotary assemblies prone to alignment deviation.

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

1. Excellent self-aligning capacity to adapt shaft bending and assembly misalignment
2. Capable of bearing radial load plus slight bidirectional axial load
3. Low friction torque, smooth and quiet medium-speed continuous operation
4. Straight bore design for direct mounting on standard solid shafts
5. Robust double row ball layout, suitable for light alternating impact loads
6. Customizable options: OEM laser marking, anti-rust treatment, special lubrication formula
   Reduce abnormal wear risk for shafts with poor coaxiality.

• Industrial ventilation fans, blowers and air handling equipment
