GQZ 23128.EMW33C3 Spherical Roller Bearing 140×225×68mm W33 Grease Groove C3 Clearance For Mining Mill Equipment

23128.EMW33C3 belongs to double row spherical roller bearing of 231 series. E represents reinforced optimized internal geometry for higher load capacity; M means solid machined brass cage; W33 stands for outer ring with annular lubrication groove and three lubrication holes; C3 is larger-than-standard radial internal clearance. Spherical raceway design provides excellent self-aligning capability to compensate shaft deflection and installation misalignment. It can bear heavy radial load and bidirectional axial load simultaneously. Widely matched on ball mills, crushers, vibrating screens, cement and mining machinery working under continuous vibration and temperature rise.

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

Complete dimension drawings and load data available on request.

1. E-type upgraded roller arrangement, uniform stress distribution, strong anti-fatigue and shock resistance
2. W33 integrated lubrication channel, convenient for centralized grease replenishment without bearing disassembly
3. C3 extra clearance reserves space for thermal expansion under long-term high-temperature operation
4. Outstanding self-aligning performance, adapts to shaft bending and assembly alignment errors
5. Machined solid brass cage maintains stable operation under heavy vibration and medium-high temperature
6. Customizable options: OEM laser marking, special clearance grades, high-temperature surface treatment Effectively reduce dry friction wear and extend service life of heavy industrial rotating assemblies.
