Super Open Linear Bearing SKB-OP

Super Open Linear Bearing SKB-OP
ISUTAMI SKB-OP super open linear bearing, also known as SKB-OP super open linear ball bearing or SKB-OP super open linear bushing bearing. S is the abbreviation of super, KB is the code name of the European standard series in linear bearings, OP is the abbreviation of open. This metric series is suitable for European markets, such as Germany and France.

SKB-OP super open linear bearing body is composed of a POM holder, high carbon bearing steel balls and some high carbon steel ball plates. The sealing ring is from the side of the bushing, usually marked with P or U in the model number, fasten the seal on both sides.

Super Open Linear Bearing SKB-OP Features

The specifications of the SKB-OP super open linear bearing are basically the same as KB-OP open linear bearing of the same specification, but there are some differences:
The inner diameter (dr) ranges from 12mm to 50 mm;
The outer diameter (D) ranges from 22mm to 75 mm;
The length (L) range is 32-100mm;
Opening angle (α) ranges from 54°to 68°
The basic dynamic load rating (C) range is 126-1169kgf, which is 3 times that of the KB-OP open linear bearing of the same specification;
The basic static load rating(Co) range is 112-810kgf, which is larger than the KB-OP open linear bearing of the same specification.
Please see the table for specific parameters.

The basic dynamic load rating of SKB-OP super open linear bearings is greater than the basic static load rating, this is different from ordinary KB series linear bearings, and the difference between the two loads varies significantly with size. In terms of weight, since the main frame uses POM engineering plastics, the weight is smaller than ordinary KB-OP linear bearings. Moreover, its moving life is 27 times that of ordinary KB-OP open linear bearings of the same specification.

SKB-OP super open linear bearing can be equipped in KBE standard linear bearing pillow blocks and KBB-OP standard linear bearing pillow blocks with a corresponding linear shaft.

In addition, the ball plate of SKB-OP super open 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 and reduce the installation time and installation costs.

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