NTN bearings are most representative of the rolling bearing, widely used. For high speed or high speed operation, and very durable, without regular maintenance. And the class NTN bearing friction coefficient is small, extreme high speed, simple structure, low cost, easy to achieve high manufacturing precision.
Size range and diverse forms, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used class of NTN bearings. The main radial load, also can withstand a certain amount of axial load.
Select a larger axial clearance radial load carrying capacity increase, when the contact angle of pure radial force is zero. When the axial force, the contact angle is greater than zero. Commonly used stamping Ribbon Cage, machined solid cage, sometimes with nylon frame.
NTN bearings installed in the shaft, the axial clearance in the range of NTN bearings, shaft or housing to limit the two directions of the axial displacement, it can be positioned in the bi-axial direction. In addition, the class also have some bearing NTN-aligning capability, when compared to shell hole tilt 2 'to 10', still work, but has some influence on NTN bearing life. NTN bearing cage mostly steel stamping Ribbon Cage, a large multi-use vehicle NTN bearing metal solid cage.
NTN Bearing commonly used in transmission, instrumentation, motors, appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery.
