GQZ 21313D1C3 Spherical Roller Bearing 65×140×33mm C3 Clearance For Crusher And Vibrating Screen Equipment

21313D1C3 is double row spherical roller bearing with D1 optimized internal geometry and C3 radial internal clearance. The spherical raceway design provides outstanding self-aligning capability to compensate shaft misalignment. It can bear heavy radial load and bidirectional axial load simultaneously. Specially suitable for equipment with strong vibration, impact load and possible shaft deflection. Widely used on crushers, vibrating screens and mining machinery.

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

Complete dimension drawings and load data available on request.

1. D1 optimized internal profile, uniform roller stress distribution, enhanced shock resistance
2. Superior self-aligning performance, tolerant of shaft deflection and mounting misalignment
3. C3 enlarged clearance, ideal for vibrating machinery under temperature rise and heavy vibration
4. Capable of heavy radial load plus bidirectional axial load
5. Machined brass cage ensures stable operation under continuous vibration and high temperature
6. Customizable options: OEM laser marking, special heat treatment, high-temperature grease
