Features of Linear Bearings

Linear bearing often used with quenching line transmission shaft, a systerm for rectilinear movement. It has lower loading capacity duLinear bearing is a low-cost linear motion system used with the cylindrical shaft for unlimited travel. The working load of such bearings is small due to the point contact of the ball and the shaft. The balls can rotate with minimal frictional resistance, thus obtaining high-precision smooth movement.


 

Principle of Operation
Linear bearing is a linear motion system, used for linear stroke and cylindrical shaft. Because the bearing ball is in contact with the bearing jacket point, the steel ball rolls with the minimum friction resistance, so the linear bearing has small friction and is relatively stable. It does not change with the bearing speed, and can obtain the smooth linear motion with high sensitivity and high precision.

Application of Linear Bearings

Axis machine tools, presses , tool grinder, automatic gas cutting machine,Textile machinery, printing machinery, printer, card sorting machines, food packaging machines and other industrial machinery sliding parts ect.

How to install linear bearings?

1. Before installing linear bearings, the raw edges, dirt and surface scars of the mechanical mounting surface must be removed. Linear bearings are coated with antirust oil. Please clean the datum surface with cleaning oil before installation. Usually, the datum surface is easy to rust after removing the antirust oil.

2. the linear bearing will be gently placed on the bed, the use of lateral fixing screws or other fixing fixture to make the line rail and the side mounting surface gently fit. Before installation and use, it is necessary to confirm whether the screw holes are consistent. Assuming that the machining holes of the base are not consistent and the bolts are forcibly locked, the combination accuracy and use quality will be greatly affected.

3. Tighten the positioning screw of the linear bearing in order from the center to both sides, so that the track is fitted with the vertical mounting surface, and stable accuracy can be obtained from the central position to both ends. After the vertical datum is tightened slightly, the locking force of the lateral datum is strengthened, so that the linear bearing can practically fit the lateral datum.

4. Use the torque wrench to lock the torque one by one according to various materials, and slowly tighten the positioning screw of the linear bearing slide rail.

5. Use the same installation method to install the auxiliary rail, and install the slide seat to the main rail and auxiliary rail individually. Note that after installing the linear slide on the slide seat, many accessories cannot be installed due to the limited installation space. The required accessories must be installed together at this stage.

6. Gently place the moving platform onto the sliding seat of the linear bearing main rail and auxiliary rail, and then lock the lateral pressing screw on the moving platform, which can be completed after installation and positioning.
