Linear Bushing The linear bearing is used in conjunction with the cylindrical shaft for unlimited linear motion. Due to the point contact with quenched drive shaft, the ball allows small load. In addition, the steel balls rotate with minimal friction resistance, so as to obtain high-precision smooth movement. Therefore, this low-cost product is mainly used in light industry machinery that moves in straight line, such as CNC machine tool, laser welding machine, tile cutter, mitre saw, paper bowl machine, engraving machine, screen printing machine, etc. Structure and Characteristics C&H linear motion bearing is composed of outer ring, balls, retainer and end ring. The retainer constrains balls in a circular orbit, while the end ring allows the retainer to be fixed in the outer ring. 1. After heat treatment, the outer ring enjoys sufficient hardness, so as to ensure long traveling life and satisfactory bearing capacity. 2. The common type linear bearing can be easily installed in any direction. It can work accurately when used together with the shaft. The mounting surface is also easy to process. 3. Each set has interchangeability due to the standardized size and high machining accuracy. This brings great convenience for replacement of worn or damaged ones. 4. With complete models for option, the product can meet the different needs of different customers. C&H is a specialized linear bearing manufacturer and supplier in China. We offer a vast array of products, including long type linear bearing, round flange mount linear bearing, linear shaft, and more.
