Product Details

Interchanged linear guides are divided into THK series linear guides and HIWIN series linear guides.it’s easy to assemble and repair.

The important is that interchanging linear guides have high cost-effective, assemble on the same size and high precision, high reliability CNC machine or other general equipment or device.

Interchanging Linear guides are mainly used in general requirements, such as lathes, woodworking machines, handling machines, transport devices, industrial automation machines, etc.

The design of a plain bearing depends on the type of motion the bearing must provide. The three types of motions possible are:

  • Journal (frictionradial or rotarybearing: This is the most common type of plain bearing; it is simply a shaft rotating in a bearing.In locomotive and railroad carapplications a journal bearing specifically referred to the plain bearing once used at the ends of the axles of railroad wheel sets, enclosed by journal boxes(axleboxes). Axlebox bearings today are no longer plain bearings but rather are rolling-element bearings.

  • Linear bearing: This bearing provides linear motion; it may take the form of a circular bearing and shaft or any other two mating surfaces (e.g., a slide plate).

  • Thrust bearing: A thrust bearing provides a bearing surface for forces acting axial to the shaft.One example is a propeller shaft.


Integral plain bearings are built into the object of use as a hole prepared in the bearing surface. Industrial integral bearings are usually made from cast iron or babbittand a hardened steel shaft is used in the bearing.

Integral bearings are not as common because bushings are easier to accommodate and can be replaced if necessary.[1] Depending on the material, an integral bearing may be less expensive but it cannot be replaced. If an integral bearing wears out, the item may be replaced or reworked to accept a bushing. Integral bearings were very common in 19th-century machinery, but became progressively less common as interchangeable manufacture became popular.

For example, a common integral plain bearing is the hinge, which is both a thrust bearing and a journal bearing.
