Do you know the function and selection skills of the slider bearing?

Adding lubricant to the upper slider bearing can make the product more orderly and avoid confusion. In order to make the Shangyin slider better operate, it has a higher rated load than linear bearings, and can withstand a certain amount of torque at the same time, and can be used under high loads to achieve high-precision linear motion.

The linear motion guide composed of the upper slider bearing is used to support and guide the moving parts in a reciprocating straight line in a given direction. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides. Linear bearings are mainly used in automated machinery, such as Germany. Imported machine tools, bending machines, laser welding machines, etc., of course, have linear bearings and straight shaft supports. The upper slider bearing are mainly used for mechanical structures with high precision.

Compared with the flat guide rail, the cross-sectional shape of the upper slider bearing also needs to be machined from the groove on the guide rail to facilitate the movement of the sliding element. The shape and number of the groove depend on the function to be completed by the machine tool. When the slider is used as a linear guide with high positioning accuracy, because the contact method of the linear guide is roll collision, the collision coefficient not only drops to 1/50 of the sliding guide, but also the collision force is negligible.

Therefore, when the bed is working, there will be no sliding phenomenon, and M-level positioning accuracy can be achieved. Simple and interchangeable assembly only needs to mill or grind the equipment surface of the guide rail on the machine tool table, and fix the guide rail and the slide block on the machine table with a specific torsion force according to the recommended steps to reproduce high-precision machining .

The upper slider bearing are interchangeable, and can be interchanged with sliders, guide rails, and even linear guide rails. High-precision guidance can be obtained from scratch. If the lubrication arrangement is simple and the sliding rail lacks lubrication, it will directly form a metal contact surface to resist the loss of the bed. However, the sliding guide is not easy to meet the lubrication, and it needs to drill the oil in the proper position of the bed. The linear guide rail has been installed on the slider nozzle, which can be directly injected with grease from the oil gun, or can be replaced with a special oil pipe joint, connected to the oil supply pipe for shearing, and automatically lubricates the oil supply machine.

When choosing the slider bearing, the first choice is the slider form. Although the flange type is better than the four-way type, the price is more expensive. Second is the size selection. The width of the upper silver slider bearing is related to the load and other parameters to check the service life of the rail; there is also a fixed form of the upper slider, such as A upper lock type B lower lock type C upper or lower lock formula.

Customers can assemble and use the slider bearing by themselves to ensure accuracy; when the silver slider is fixed, the radial clearance of the linear guide is defined as the radial clearance. At the center of the length, the slider moves gently up and down. At this time, the radial displacement of the center of the slider takes into account the impact of vibration generated by the reciprocating motion, and the service life and accuracy of the negative gap bring good results.
