Linear ball bearing bushings type KH has most compact design of all available types. They are suitable for linear motion applications where compact dimensions are required. KH linear bushings have seals from both sides (designation PP). Linear Bushings KH are available for shaft sizes from 6 mm to 50 mm. This type of linear bearing have rigid steel ball retainer.


KH pressing bush linear bearings, also known as KH pressing linear ball bearings or KH pressing linear bushing bearings, are available in all markets and industries of metric units.


KH stamping linear bearing is composed of hard bearing steel bushing and internal plastic cage and high carbon steel balls. Both ends of the bushing are stamped and closed, and the retainer is fixed inside the bushing, and the sealing ring can be added at both ends, usually indicated by U or P, the seal is made of NBR material.


Linear bearing KH series has a range of 4-9 column ball rows, which is generally 1-3 columns more than the standard linear bearing of the same specification. The KH linear bushing includes a number of different models, such as KH0622, KH1630, KH5070, and so on. These models have large differences in the size, load capacity, and weight. Among them, the model KH0622 comes with an outer diameter of 12mm, an inner diameter of 6mm, and a length of about 22mm, as well as is able to withstand a dynamic load of 400N. In addition, the model KH5070 mini linear bushing is the largest product in this series, with an inner and outer diameter of 50mm and 62mm respectively. Available in a weight of 252gf, it can withstand a dynamic load of 5610N and a static load of 6430N.


The movement principle of the KH linear bearing is rolling friction. The bearing is in contact with the cylindrical shaft through the steel balls. The steel balls rotate with a very small frictional resistance, so that high-precision smooth motion can be obtained, which is suitable for low-load as well as high-speed motion.



It is suitable for all kinds of industrial equipment, robots, medical equipment and other products with higher.
