Standard type
Several methods of mounting the bearing housing with snap rings and retaining plates.
Mounting the bearing with the set screw will cause the bearing casing to deform and should be avoided as much as possible.
Flange type
When installing a flange type linear bearing, the precision of the surface of the bearing housing must be accurate.
Adjustable type (small opening type)
The bearing is perpendicular to the opening in the bearing housing to obtain a uniform preload in the circumferential direction.
Large open type
If used in conjunction with a suitable housing, large-open bearings can also be adjusted for clearance, even with light preload.
.Precautions during installation
When the linear bearing is installed in the bearing housing, auxiliary work should be used to avoid direct tapping of the end face or the sealing ring. The bearing should be evenly introduced, and the buffer plate should be used to load it with a gentle tap.
To thread the optical axis into the linear bearing, the shaft and the centerline of the bearing must be aligned. If the shaft is inserted obliquely, the balls may fall off or cause the cage to be deformed and damage the linear bearings.
The applied load should be evenly distributed over the entire bearing, especially when subjected to transient loads. Two or more bearings should be used. Linear bearings are not subject to rotating loads, which can cause accidents.
