29338Thrust roller bearings

Thrust roller bearing is used to carry axial load of axial, radial joint load, but shall not exceed 55% of the axial load, radial load this kind of bearing with low friction factor, high speed, and has a self-aligning performance.
Ordering hotline:
Thrust roller bearing is used to carry axial load of axial, radial joint load, but shall not exceed 55% of the axial load, radial load compared with other thrust roller bearings, the bearing friction factor is low, high speed, and has a self-aligning performance.
After into the thrust roller bearing thrust roller bearing pressure should be flexible rotation without blocking.If there are any obvious rotation is not flexible, indicates the size of the shaft is too big, tolerance to downgrade.Such as thrust roller bearing pressure into the shaft by hand after the rotation has obvious "sasha vujacic" feeling, may be the shaft or shaft roundness tolerance is too big.So in good control of shaft and thrust roller bearing chamber of tolerance when also want to control the roundness, at present many domestic manufacturers to control the tolerance only, not to control the roundness.
Because of thrust roller bearing is high precision products, such as improper assembly is easy to cause damage to the thrust roller bearing channel, lead to damage of thrust roller bearing.Thrust roller bearings in the assembly shall have a dedicated mold, not casually, only small circle of stress when pressure into the shaft, pressure can force the circle circle.Require the use of pneumatic or hydraulic assembly, lower die when being connected to outside the state level, such as with sloping channel leads to thrust roller bearing due to mechanical damage, and make the guide ring thrust roller bearings.
Standard design of thrust roller bearing used car metal solid cage, according to user requirements, also can use other type or material of the cage.Thrust tapered roller bearings can only carry a one-way axial load, one-way axial displacement can limit bearing, so it can be used as a one-way axial positioning.Compared with cylindrical roller thrust bearing, large carrying capacity, relative sliding is small, but limit rotational speed is low.
