First, the bearing box device:
1. Standard type: Several methods of using the snap ring and the fixed plate device bearing box. The bearing with the set screw device will cause the bearing shell to be deformed; it should be prevented as much as possible.
2. Flange type: When installing flange type linear bearing; the precision of the inner hole of the bearing box cooperated with it must be accurate.
3, adjustable type (small opening type): the opening on the bearing and the bearing box is straight; you can get a uniform preload in the circumferential direction.
4, large opening type: if used in cooperation with the appropriate bearing housing; large opening bearings can also be used for gap adjustment; even able to add light preload.
Second, the device should pay attention to:
1. When the linear bearing is installed in the bearing seat; auxiliary work should be used; prevent the end face or seal ring from being directly tapped; the bearing should be evenly introduced; use the buffer plate; by gently tapping and loading.
2. Pass the optical axis into the linear bearing; the center line of the shaft and the bearing must be in a straight line. If the shaft is twisted, the ball may fall; or the cage may be deformed; and the linear bearing may be damaged.
3. The applied load should be evenly distributed over the entire bearing; especially when receiving the load when 霎; two or more bearings should be used. The linear bearing does not accept the rotating load; otherwise it can cause accidents.
