Import inside the bearing axial clearance can be achieved with the move in the axial direction of the outer ring position. The main common to adjust the axial clearance of imported bearings within two, namely, adjusting pads with adjusting bolt method.china bearing company

    1 adjusting shim method: put a soft material in imported bearing cap and the imported bearing between the end fill (soft steel or flexible paper) gasket; adjustment, hold the gasket is installed on the bearing end cap, side evenly tighten the screws on the tight bearing end cap, side of the axis of rotation by hand, until the bearing rolling elements in contact with the outer ring axis internal clearance; when measuring the gap between the bearing end cap and the bearing end face, coupled with bearings In normal operation require an axial gap; is desired fill put the total thickness of the gasket, and then prepared gasket filled in between the end faces of the bearing cover and the bearing housing, and finally tighten the screws.spherical roller bearing

    2 adjustment bolts method: the pressure ring pressure on imported bearing outer ring, by adjusting bolt pressurized; before the pressure adjustment first measurement to adjust the pitch of the bolt, and then tighten the adjusting bolt slowly, until the bearing no gap, and then calculate the corresponding rotation angle adjustment bolt. For example, the pitch of 1.5mm, the bearing normal operation gap, then adjusting bolt required angle of rotation for the 3600 0.15/l.5 = 360; when reverses the adjustment bolt 360, miniature bearings 0.5mm axial gap, and then with a stopper pad to be fixed.
