How to distinguish the usage between linear bearings and mounted linear ball bearings?

The distinction between linear and mounted linear ball bearings:

1.According to the state of the linear bearing bearing capacity ⇒ Forced linear bearing selection mounted linear ball bearings

2. Selected according to the space and construction surface around the assembled linear bearing

The linear bearing is divided into two types: the self-moving structure and the bearing fixing to make the shaft rotate. For example, a configuration diagram of an X-Y-Z-θ driving table in which a shaft is used as a guide shaft.
The X-axis movable part of part a) is subjected to the inertial force of the weight of the movable body by the linear bearing, and the linear bearing needs to be tightly fixed.
b) The linear bearing is fixed to the bearing housing. Due to the cylinder drive shaft structure, the axial fixed portion of the linear bearing only receives the reaction force of the friction force, so the linear compact design is adopted.

In addition, the installation direction of the Y-axis linear bearing is reversed with respect to the rotation axis of the θ drive table and the two axes, and the linear bearing can also be highly rigid with respect to the turning moment.
Part c) If it is considered from the movable direction of the shaft, it is the same as the part b) and will not be subjected to a large force.Mounting linear ball bearings:
Mounted linear ball bearings are generally mounted using a retaining ring or baffle.

Mounting linear ball bearings installation angle note:
The mounted linear ball bearings differ in the number and type of shaft diameters and the number of rows of balls in the bearing. The number of ball rows of a linear bearing is generally an equiangular arrangement of 4 columns to 6 columns.
When the mounted linear ball bearings are used in the horizontal direction, the mounting angle is as far as possible to avoid the position where the ball column is directly above, because the concentrated load is easily generated when the ball column is directly above.

ZYSL company specializes in mounted linear ball bearings for many years. All raw materials and accessories have been carefully selected to ensure a good user experience.
