Square Flange Linear Bearing KBK

Square Flange Linear Bearing KBK
ISUTAMI KBK square flange linear bearings, also known as KBK square flange linear ball bearings or KBK square flange linear bushing bearings. KB is the code name for the European standard series in linear bearings. K means square. It is suitable for European markets using metric units, such as Germany and France.

KBK square flange linear bearing, its bushing and steel balls are made of high carbon bearing steel. The ball retainer is made of metal steel, stainless steel or POM material. The retaining ring, usually represented by U or P, is made of NBR. The ball retainer is installed in the bushing with the steel balls and sealed with a retaining ring from one side or both sides of the bushing.

Square Flange Linear Bearing KBK Features

KBK square flange linear bearing bushing surface is complete and seamless, there is not any outer stop groove, and there is a circular flange at one end of the bushing, with four circular connecting holes evenly distributed in the flange, to fix the bearing. The ball row number of the KBF European series supplied by ISUTAMI varies according to the bearing size, and ranges from 4 to 6. Inner diameter (dr) range and tolerance, outer diameter (D) range and tolerance, length (L) range and tolerance, maximum radial eccentricity, basic dynamic load rating (C) range, basic static load rating (Co) range, etc.,are all basically the same as KBF circular flange linear bearing, KB standard linear bearing and KB-AJ adjustment linear bearing. The specific parameters are shown in the table.

In addition, KBK square flange linear bearing, its flange length (K) ranges 22-106mm; the height of the flange is 5-18mm; because of the flange, its weight is larger than the KB standard linear bearing of the same specification.

The KBK flange linear bearing has a square flange with a bushing bearing as a whole, and the corresponding components make the axial positioning simple. It does not need to be fixed in the matching bearing pillow blocks like the non-flanged linear bearing. It becomes very economical and saves time, and it has also reduced the overall weight of the linear bearing assembly,to make operation smoother.

Unlike ball bearings, the basic static load rating of BKF circular flange linear bearings is greater than the basic dynamic load rating, and as the size increases, this value gap continues to expand, even up to 2 times.

Flange bearings are suitable for all kinds of industrial equipment, small rotary motors, office equipment, micro motor soft drives, pressure rotors, dental drills, hard disk motors, stepper motors, video recorder drums, toy models, pulleys, rollers, In transmission equipment, entertainment equipment, robots, medical equipment and other products.
