Pressing Bush Linear Bearing KH

Pressing Bush Linear Bearing KH
ISUTAMI 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.

Pressing Bush Linear Bearing KH Features

KH type linear bearing 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, and the inner diameter (d) ranges from 8 to 50 mm, diameter (D) range is 15-62mm, the length range is 24-70mm, the dynamic load rating range is 44-561kgf, and the static load rating range is 29-643kgf. Compared with ordinary linear bearings, most of the KH type linear bearings, their dynamic load rating exceeding the static load rating, but the static load rating of KH4060 and KH5070 exceeds the dynamic load rating. Generally speaking, compared with the standard linear bearings of the same specification, the KH type has a high dynamic load rating. Except for KH5070, the KH series of other specifications must have a static load rating that exceeds that of a standard linear bearing.

Compare with the standard Linear Bearings, KH type linear bearings have the characteristics as below:

1. Friction is small, small power consumption, high mechanical efficiency, easy starting.
2, Size standardization, interchangeability, easy installation and removal, easy maintenance.
3, Compact, lightweight, the axial dimension is more narrow.
4, High precision, high speed, low wear, and long life.
5, suitable for mass production, stable and reliable quality, high production efficiency.

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 requirements.
