31309 Steep Angle Mechanical Gearbox Bearing | 45x100x27.25mm
- Dimensions: 45mm (ID) x 100mm (OD) x 27.25mm (T)
- Load Ratings: Dynamic (Cr) = 106 kN, Static (Cor) = 114 kN
- Limiting Speed: 4000 rpm (Oil lubrication)E/Y Factors: $e = 0.83$, $Y = 0.73$ (indicates top-tier performance against heavy thrust forces) Sealing: Open configuration to allow smooth integration with centralized oil sumps
The 31309 tapered roller bearing is optimized for medium-sized wind turbine yaw drives, heavy conveyor pulleys, and industrial mixers. Its 45mm bore paired with a massive steep-cone angle provides an outstanding ratio of axial-to-radial load capacity. The optimized roller-end/flange contact geometry cuts friction by up to 20% compared to legacy designs, facilitating lower operating temperatures under full load.
