Wear particles could migrate inside the jis b 0401, and cause vibration and degradation. Fits also minimize vibration during rotation. It is necessary to choose a proper fit for each application because improper fits can jis b 0401 only degrade the bearing performance, but also they could cause seizure from burning and early failure. Designs of shaft and housing In the case of interference fits, the interference causes a change in radial clearance.

Combination with plastic parts Fit can also be the tightness between the housing bore and the bearing outside diameter.

Shield and Seal 5. When creep happens, abnormal heat, and wear particles can be generated due to slip wear. When the bearing is fitted to the shaft uis housing by glue without interference, it is necessary to jis b 0401 the proper clearance to enhance the effectiveness of the glue.

Tolerance and precision grade 8. It is always fitted to either a shaft or a housing bore.

Abnormal heat hastens the degradation of jia and retainers. Rotating inner ring load: Definitions Rotating inner ring load: The change in radial clearance generated by interference can be calculated as below. When a ball bearing is used, it is not used only by itself. Vibration by forced rotation Please be aware that the roundness jis b 0401 the ring raceways could worsen because of jis b 0401 curing stress of the glue.

Fits are classified into clearance fit, 001 fit, and interference fit. Fits Fits help bearings not to have unfavorable slip called “Creep” by firmly securing the inner ring and outer ring on the shaft and in the housing, respectively. Fit is the value of tightness between the shaft and bearing bore jis b 0401 the bearing is installed.

Securing with glue When the bearing is fitted jis b 0401 the shaft and housing by glue without interference, it is necessary to select the proper clearance to enhance the effectiveness of the glue. Application conditions, environment, required performance 3. Interference fit of the outer ring to the housing The sketches drawn in solid lines and dotted lines are the bearing prior to a jis b 0401, and the bearing after a fit, respectively. Fits help bearings not to have unfavorable slip called “Creep” by firmly securing the inner ring and outer ring on the shaft and in the housing, jis b 0401.

It is recommended to consult with the glue manufacturer because the proper clearance depends on the type of glue. The sketches drawn in solid lines and dotted lines are the bearing prior to a fit, and the bearing after a fit, respectively.
