What are the advantages of linear bearing for square tube?

1.linear bearing for square tube has high positioning accuracy

When using a linear bearing for square tube as the linear guide, since the friction mode of the linear guide is rolling friction, not only the friction coefficient is reduced to 1/50 of the sliding guide, but also the gap between the dynamic friction force and the static friction force becomes small. When the bed is moving, there will be no slippage, and it can reach the [ultra high precision level] um level as accuracy.

2.The linear bearing for square tube has less wear and can maintain accuracy for a long time.

The traditional linear bearing for square tube inevitably causes poor platform movement accuracy due to oil film countercurrent, and insufficient lubrication during movement, resulting in wear of the running track contact surface, which seriously affects accuracy, and the wear of rolling guides Very small, so the machine can maintain accuracy for a long time.

3. Use high-speed motion and greatly reduce the driving horsepower required by the machine

Because the linear bearing for square tube has very low friction when moving, it only needs less power to make the bed run, especially when the work mode of the bed is regular reciprocating movement, which can significantly reduce the point force loss of the machine. , And the heat generated by its friction is small, which is suitable for high-speed operation.

4.linear bearing for square tube

Due to the special beam structure design of the linear bearing for square tube, it can bear the load in the up, down, left and right directions at the same time. It does not want to slide and guide the side load in the direction of the parallel contact surface.

5.The assembly of linear bearing for square tube is easy and interchangeable

When assembling a linear bearing for square tube, as long as the assembly surface of the guide rail on the bed is milled or ground, and the guide rail and the slider are fixed to the machine according to the recommended steps, the high precision during processing can be valued. Traditional Sliding guide, it is necessary to shove the running track, which is time-consuming and time-consuming, and once the machine accuracy is poor, it must be shoveled once. The linear bearing for square tube is interchangeable, and the slider cargo rail can be replaced to It is a linear guide group, and the machine can regain high precision guidance.

6.Simple lubrication structure for linear bearing for square tube

If the linear bearing for square tube is insufficiently lubricated, it will be caused by direct contact with the metal on the contact surface. It is not easy to lubricate the slide guide sufficiently. It is necessary to drill and supply oil at the appropriate position on the bed. In the device nozzle, grease can be injected directly with a grease gun, or a special oil pipe connector can be connected to the oil supply pipe to lubricate the automatic oil feeder.
