First, adhere to the NTN tapered roller bearing and its surrounding environment, even if the small dust that is invisible to the naked eye enters the NTN tapered roller bearing; it will also add bearing wear; oscillation and noise. NTN tapered roller bearing and its surrounding accessories should adhere to Hygiene, especially dust and dirt, things and work environment also need to be clean.
Second, the use of the device should be carefully and carefully do not agree to strong stamping; do not answer the application of the hammer; directly tap the NTN tapered roller bearing; do not allow the pressure to pass through the rolling body.
Third, use appropriate and precise devices to try to use special things; try to avoid the use of cloth and short fibers and the like.
Fourth, to avoid the rust of NTN tapered roller bearings directly take NTN tapered roller bearings; wash the sweat on your hands; and apply high-quality mineral oil before handling; especially in the dry season and summer Anti-rust. However; under certain special operating conditions; the bearing can obtain a better life than the traditional accounting; especially in the case of light load. These special operating conditions are; when the rolling surface (track and roll) Appearance damage caused by a smooth oil film effectively separating and restraining contaminants. In fact; under ambition; the so-called Eternal NTN tapered roller bearing life is achievable.
According to the application site, operating conditions and environmental conditions, the standard scale and accuracy are selected. Suitable NTN tapered roller bearings are the conditions for ensuring the bearing life and feasibility.
1. Application: Tapered roller bearings are suitable for accepting radial and axial combined loads with radial loads; usually used with two sets of bearings; first and foremost for the front and rear wheels of the car, automatic bevel gears, differential Transmission parts such as reducer and reducer.
2, promise speed: in the correct, smooth and outstanding environment; the maximum speed of the NTN tapered roller bearing is 0. 3-0. 5 times. Normally under normal conditions; the maximum speed of 0.2 times is the most suitable .
3, promised skew angle: tapered roller bearings usually do not allow the shaft to be skewed relative to the shell hole; if there is skew; the maximum does not exceed 2'.
4, promise temperature: in the normal load; and the smoothing agent has high temperature resistance; and smooth and plentiful conditions; usually NTN tapered roller bearings allow to operate at -30 Â° C -150 Â° C ambient temperature.
