Linear guide bearings, also known as linear bearings, are also rolling parts that can do linear reciprocating operation. The sliding guide has the advantages of simple structure, convenient manufacture and high contact stiffness.

Linear bearing often used with quenching line transmission shaft, a systerm for rectilinear movement. It has lower loading capacity duLinear bearing is a low-cost linear motion system used with the cylindrical shaft for unlimited travel. The working load of such bearings is small due to the point contact of the ball and the shaft. The balls can rotate with minimal frictional resistance, thus obtaining high-precision smooth movement.

It consists of an outer ring, an inner ring, a set of steel balls and a set of cages. It mainly bears pure radial loads, but also can bear joint loads. We have three seal types：ZZ type、2RS type、Open type.

Single row angular contact ball bearings can only withstand axial load in one direction. When such bearings are subjected to pure radial load, they must be installed and used in pairs because the line of action of the rolling body load and the line of action of the radial load are not in the same radial plane, resulting in an internal axial component.

Needle Roller Bearings (needle bearing) is a cylindrical roller with roller bearings, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-section,has a higher load bearing capacity, equipped with a thin and long needle bearing roller (roller diameter D≤5mm,L / D≥2.5, L is the length of the roller), so radial structure is compact, its diameter size and load capacity and other types of bearings, minimum diameter, especially for radial dimensions limited support structure.
