Super Standard Linear Bearing SKB

Super Standard Linear Bearing SKB
ISUTAMI SKB super standard linear bearings, also known as SKB super standard linear ball bearings or SKB super standard linear bushing bearings. S is the abbreviation of super. KB is the code name of the European standard series in linear bearings. It is suitable for European markets using metric units such as Germany and France.

The SKB super standard linear bearing body is composed of a POM resin holder, high carbon bearing steel balls and high carbon steel ball plates. The sealing ring is on one side or both sides of the bushing, usually marked with P or U in the model.

Super Standard Linear Bearing SKB Features

The specifications of the SKB super standard linear bearing are basically the same as those of KB standard linear bearing of the same specification, but there are some differences:
The inner diameter (dr) ranges from 12 to 50 mm;
The outer diameter (D) ranges from 22 to 75 mm;
The length (L) range is 32-100mm;
The basic dynamic load rating (C)range is 126-1169kgf, which is 3 times that of the KB standard linear bearing of the same specification;
The basic static load rating (Co) range is 112-810kgf, which is larger than the KB standard linear bearing of the same specification.

SKB super standard linear bearing can be replaced by KB standard linear bearing, generally installed to KBA standard linear bearing pillow blocks, KBA-S short linear bearing pillow blocks, KBA-L long linear bearing pillow blocks, KBB standard linear bearing pillow blocks and KBSB standard linear bearing pillow blocks, used with the linear shaft.

Unlike ordinary KB series linear bearings, the basic dynamic load rating of SKB super standard linear bearings is greater than the basic static load rating, and the difference between the two loads varies significantly with size; for weight, since the main frame of SKB super linear bearing uses POM engineering plastic, the weight is smaller than ordinary KB linear bearings of the same specification. Moreover, its moving life is 27 times that of ordinary KB linear bearings.

In addition, the ball plate of the SKB super standard linear bearing is convex, which can provide the pivot point in the center. The pivot point can automatically adjust the bearing by 1°. This performance can compensate for the inaccurate machining of the base point, reduce the installation time and installation costs.

SKB super standard linear bearings can be used in high-performance automation equipment, industrial robots, electrical equipment, measuring instruments and so on.
