INA non-standard bearing failure causes

- Jul 04, 2019-

The life of INA bearings is closely related to manufacturing, assembly and use. It must be done at every stage in order to keep the non-standard bearings in optimal operation, thus extending the service life of the bearings.

After the INA bearing is installed, check the operation in order to check if the installation is correct. The small machine can be rotated by hand to confirm whether the rotation is smooth. The inspection items have poor operation due to foreign matter, scratches, and indentations. The installation is poor, the torque generated by the mounting is not stable, and the torque is too large due to too small clearance, installation error, and sealing friction. Wait. If there is no abnormality, the power running can be started.

The power running starts from the no-load low speed and slowly increases to the rated operation of the specified conditions. The items to be checked during the test run are whether there are abnormal sounds, changes in temperature of non-standard bearings, leakage or discoloration of lubricants, etc. If an abnormality is found, stop the operation immediately, check the machine, and remove the INA bearing check if necessary.
