Linear plain bearings are linear positioning bearings with an infinite stroke length. These linear guidance systems may be miniature sliding guide systems, Permaglide linear plain bearings and Permaglide linear plain bearing units as well as flat guide systems. The miniature sliding guide system consists of a rail/slider system and a maintenance-free sliding layer. The Permaglide linear plain bearing unit is a low maintenance required Permaglide bushing mounted in a light metal ring. The flat guiding system is a guiding system for maintaining a very low sliding layer on the guide rail.
The working surface of the linear plain bearing is in contact with the surface of the shaft in the form of a surface, and the linear sliding bearing of the transmission is in contact with the surface of the shaft in the form of a dotted line; this determines that the LIN series linear plain bearing of the larger contact surface has a straight line than the ball. Sliding bearings have a higher load carrying capacity.
Linear sliding bearing working process: The linear sliding bearing is equipped with a steel ball cage inside the outer ring. The cage is equipped with a plurality of balls, and the balls are infinitely circulating. The two ends of the cage are fixed by a gasket retaining ring, and a notched window is arranged in the direction of the linear track in which the steel balls are subjected to the force work. This part is to make the loaded steel ball roll contact with the shaft with a very low friction coefficient. Relative movement.
Advantages of linear plain bearings :
1. Completely no lubrication
2. Adjustable bearing clearance
3. Automatic adjustment of clearance
4. Can withstand higher static loads
5. Service life up to 50000km and no lubrication required
6. High stain resistance
7. Low vibration and low noise
The linear plain bearing has no rollers or balls, so it has nothing to do with the mass inertia of the bearing. The high speed of Zui can reach 10m/s, and the high acceleration of Zui can reach 100G. Drylin? For light load applications, the cycle speed increases accordingly. Due to the high thermal conductivity of aluminum, the use of hard aluminum as a friction member can reduce the operating temperature of the bearing, so it can be used in short stroke and high frequency applications. Therefore, it is possible to operate at a high frequency even on a very short stroke length.
The application of linear plain bearings is widely used in industry, and its role is also very large. Many occasions are indispensable. I believe this is known to everyone, and because of this, bearings have become popular industrial products.
