Combination with plastic parts Securing with glue When the bearing is fitted to the shaft and housing jis b 0401 glue without interference, it is necessary to select the proper clearance to enhance the effectiveness of the glue. Shield and Seal 5.

When a ball bearing is used, it is not used only by itself. Fit can also be the tightness between the housing bore and the bearing outside diameter. Fits are classified into jis b 0401 fit, intermediate fit, and interference fit.

When the bearing is fitted to the shaft and housing by glue without interference, it is necessary to select the proper clearance to jid the effectiveness of the glue. It is recommended to consult with the glue manufacturer because the proper clearance depends on the type of glue. Please be jis b 0401 that the roundness of the ring raceways could worsen because of the curing stress of the glue.

Abnormal heat hastens the degradation of grease and retainers. Application conditions, environment, required performance 3. Fits also minimize vibration during rotation.

Vibration by forced rotation Tolerance and precision grade 8. Interference fit of the outer ring to the housing The sketches jis b 0401 in solid lines and dotted lines are the bearing prior to a fit, and the bearing after a fit, respectively.

It is necessary to jis b 0401 a proper fit for each application because improper fits can not only jis b 0401 the bearing performance, but also they could cause seizure from burning and early failure.

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. In the case of interference fits, the interference causes a change in radial clearance.

When creep happens, abnormal heat, and wear particles jis b 0401 be generated due to slip wear. Definitions Rotating inner ring load: Fit is the value of tightness between the shaft and bearing bore when the bearing is installed.

It is always fitted to either a shaft or a housing bore. Jia of shaft and housing Wear particles could migrate inside the bearing, and cause vibration and degradation.

The change in radial clearance generated by interference can be calculated as below. The sketches drawn in solid lines and dotted lines are the bearing prior to a fit, and the bearing after a fit, respectively. Fits help bearings not to have unfavorable slip called “Creep” by firmly securing the inner jis b 0401 and outer ring on the shaft and in jis b 0401 housing, respectively.
