According to the use of parts and conditions of use and environmental conditions to select specifications and accuracy, with the appropriate timken imported bearings is the premise to ensure bearing life and reliability.
1. Location: Tapered roller bearings are suitable for bearing radial and axial combined loads with radial loads. They are usually paired with two sets of timken bearings, mainly for front and rear hubs and active bevel gears of automobiles. , differential, reducer and other transmission parts.
2. Allowable speed: In the environment with correct installation and good lubrication, it is allowed to be 0.3-0.5 times of the limit speed of the imported bearings of timken. Under normal circumstances, it is best to use 0.2 times the limit speed.
3. Allowable tilt angle: Tapered roller bearings generally do not allow the shaft to tilt relative to the housing bore. If tilted, the maximum does not exceed 2'.
4, allowable temperature: under normal load, and the lubricant has high temperature resistance, and the lubrication is sufficient, the general bearing is allowed to work at -30 ° C -150 ° C ambient temperature.
Bearing grease selection
Improper lubrication accounts for 36% of the causes of premature bearing failure. General purpose greases do not meet the needs of a wide variety of special bearing applications. Only one or all common greases are used to meet all timken bearing applications. The problems caused will far outweigh the benefits of the unified brand. Bearing application conditions are very diverse, the correct lubrication is required to match the grease and bearing application conditions.
Bearing grease is the basis for smooth, worry-free operation and maximum reliability, even under the most extreme operating conditions. Grease prevents contaminants from entering the bearing, cushioning shock loads and preventing corrosion. Choosing the right grease in practical applications is the basic condition for obtaining the maximum service life of the bearing.
The criteria for proper lubricant selection include the type and size of the timken imported bearings, temperature, speed, load, and expected service life and relubrication cycle.
