UCF 208 Bearing Specifications

Mounting on the Shaft of UCF 208

In general using conditions, only two hexagonal setscrews can be fastened with the allen key, screw the top of setscrew to the surface of the embeddable shaft as well as possible.
The contact part of the setscrew.as shown in Figure (8.1.1), is installed into a plain to be mounted by drilling as shown in Figure (8.1.2),besides, in the case of bearing vibration and impact, or in the case of a large axial load, as shown in Figure (8.1.3) , the step cotton shaft is fixed with a screw cap, moreover, in this case, the setscrew is also tightened by using the moderately heavy torque of setscrew shown in Table.
If the force exceeding the necessary tightening torque is used to tighten the setscrew, the rotational accuracy will be affected and internal cracks may occur .
However, if the torque of the fastening setscrew is not enough, it will be loosen and dropped in working, which will cause relative sliding between the inner ring and the shaft.
Therefore, proper tightening torque must be used to tighten the setscrew, generally speaking，the Values shown as Table is appropriate .
Bearing assembly of special quenched make up for the shortcomings of the previous products of all types of inner ring quenched .Such phenomenon as inner ring cracks and setscrew loosening seldom occur.
Even in the repeated loading places where the shake and cracks occur at the same frequency, it can be fixed to the shaft without fear of accidents.
