Installation Instruction for OilLess Bearings
In most cases, OilLess Bearings are used with a press fit in the same manner as general sleeve Bearings. Fit the Bearings into housings using mandrels or press. In case of a relatively large interference, provide both the ID of the housing and the OD of the Bearing with chamfers, and fit the Bearing into the housing with mandrel for easy installation.
Break-in Instruction for OilLess Bearings
At the on start of the operations, contact surfaces of shafts and Bearing are smooth, however, microscopic irregularities are inevitable to develop after continued use. A deviation from true center alignment may also exist. Thus the initial contact between sliding surfaces could be local.
Do not immediately start a regular loaded operation. It may result in damaging the bearing surfaces, leading to a shorter service life. Instead, gradually break-in operations so to smooth out the microscopic irregularities, and allow the entire pressure support area to slowly come in contact without causing damage. This is called a “break-in for familiarity”.
