Pay attention to its high temperature adaptability when using TIMKEN bearings. This is because it is a cage made of glass fiber reinforced nylon 66. It is suitable for the steady state of working temperature not exceeding 120 degrees. This TIMKEN bearing is lubricated with oil. If the oil contains additives, it may result in a shortened life of the cage. When the temperature exceeds 120 degrees, the aged lubricant will also shorten the life of the cage. Therefore, care should be taken to observe and replace the lubricant as scheduled.
If high-temperature synthetic materials are used for sealing, consider that this very effective fluorinated material will emit harmful gases and fumes at temperatures above 300 degrees. This is especially important when using a welding torch when disassembling TIMKEN bearings.
1. The ability of TIMKEN bearing to bear load is much smaller than that of the same volume of sliding bearing. Therefore, the radial size of its rolling bearing is large. Therefore, in the case of a large load and a case where a small radial size and a compact structure are required, such as a crankshaft bearing of an internal combustion engine, a sliding bearing is often used.
2. The bearing vibration and noise are large, especially in the later stage of use. Therefore, in the case where the precision bearing is required to be high and vibration is not allowed, the effect of the sliding bearing is generally better.
3, TIMKEN bearings are particularly sensitive to foreign objects such as metal chips, once mixed with foreign matter, it will produce intermittent large vibration and noise, which will easily lead to damage. Therefore, the life of rolling bearings also has a certain limit. In short, the life of imported TIMKEN bearings is shorter than that of plain bearings.
