TIMKEN bearing metallurgical quality of the materials used to be the main factors affecting the early failure of rolling bearings. Metallurgical technology (such as vacuum degassing of steel of bearings, etc) increases, improved quality of raw material. Raw materials of quality factors in the failure analysis of bearing weight has dropped dramatically, but it's still one of the main factors bearing failure. Selection of propriety is still bearing failure analysis of essential factors for consideration.
1. installation does not allow drilling in the TIMKEN bearings, Groove, chamfer, car faces. Otherwise, prone to TIMKEN bearing ring deformations, effects of bearing accuracy and life, while cutting out the metal easier access to the bearing working surface, accelerated wear of the raceways and rolling elements, bearing causing premature failure.
2. installation does not allow direct beat Bishop TIMKEN bearing rings. Bearing base close to the shaft installed in the end celebration. Base-side surface of the bearing is according to the bearing face without typing to differentiate, deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearings, spherical roller bearings and needle roller bearings, based on no words end surface; angular contact ball bearings and tapered roller bearings, based on there face surface.
3. install the pressure should be installed when an interference fit of the ring on the end, that is, when mounted on a shaft, pressure should be added on the TIMKEN bearing inner ring side faces; while loading bearing block hole, the pressure should be on the TIMKEN bearing outer ring side face. By passing rolling elements and maintain pressure is not allowed.
4. tight fit for the inner ring, the outer TIMKEN bearings for facing up, installation, shall be separated should first be on the bearing to the shaft, and then the shaft with bearings into the housing in the shell hole; Division of separable, inner and outer rings can be installed individually.
5. in order to prevent bearing installation tilt, centerline of the shaft and housing bore when mounting bearings must coincide. If Setup is not straight, when you re-install, must pass the inner ring side face, TIMKEN bearing out of the way.
