    Precautions When Using WSBC Bearings

    1. Selection of shaft and bearing and tolerance of control room Press-in bearings WSBC bearings should be flexible without blocks in the direction of rotation. If the rotation is significantly inflexible, the size of the shaft is too large. As the tolerance of the shaft is obviously "sandy" afterturning it by hand, it may be too poor or the roundness of the shaft. Therefore, a good shaft and bearing control roomshould a...
