Product Details

Different working environments require different loads and models of products. The kinds of linear guide rail could be cut for different lengths and models to splice and install, it’s high reliability and practicability.

CHTR linear guide guideway is designed with four columns arc grooves which increase the contract area, it has been greatly improve on the loading capacity , contact stiffness and system rigidity.

Linear guides are mainly used in mechanical structures with high precision requirements, such as grinding machines, lathes, woodworking machines, handling machines, transport devices, industrial automation machines, semiconductor machinery, packaging machines, etc.

There are at least 6 common types of bearing, each of which operates on different principles:

  • Plain bearing, consisting of a shaft rotating in a hole. There are several specific styles: bushing, journal bearing, sleeve bearing, rifle bearing, composite bearing.

  • Rolling-element bearing, in which rolling elements placed between the turning and stationary races prevent sliding friction. There are two main types

    • Ball bearing, in which the rolling elements are spherical balls

    • Roller bearing, in which the rolling elements are cylindrical,taper and spherical rollers

  • Jewel bearing, a plain bearing in which one of the bearing surfaces is made of an ultrahard glassy jewel material such as sapphire to reduce friction and wear

  • Fluid bearing, a noncontact bearing in which the load is supported by a gas or liquid,

  • Magnetic bearing, in which the load is supported by a magnetic field

  • Flexure bearing, in which the motion is supported by a load element which bends.
