Welcome to Linqing Xinshengdi Bearing Co., Ltd.
31307 Steep-Cone Metric Roller Bearing | 35x80x22.75mm
- Dimensions: 35mm (ID) x 80mm (OD) x 22.75mm (T)
- Load Ratings: Dynamic (Cr) = 71.5 kN, Static (Cor) = 74.8 kN
- Axial Factor: Extremely low $Y$ calculation factor ($Y = 0.73$), maximizing axial force distribution
- Heat Treatment: Case-hardened options available for high-shock industrial environments
- Weight: 0.54 kg/piece (optimized for heavy-duty structural integrity)
Specially modified for heavy industrial speed reducers and hydraulic pump drives, the 31307 tapered roller bearing delivers uncompromising axial stiffness. Its steep contact angle allows a single row to manage immense unidirectional thrust, preventing shaft misalignment. With precision-ground rollers and strict dimensional control, this model minimizes running-in torque spikes, securing stable long-term machinery operations.
