ISUTAMI KBK-L long square flange linear bearings, also known as KBK-L long square flange linear ball bearings or KBK-L long square flange linear bushing bearings. KB is the code name of the European standard series in linear bearings, F is the meaning of square flange, L is the abbreviation of long. It is suitable for the EU markets of using metric units, such as Germany and France.

The material of KBK-L long square flange linear bearnig bushing and steel balls are high carbon bearing steel. The ball retainer is made of metal steel, stainless steel or POM, and the sealing ring, usually U or P represented, is made of NBR material. The ball retainer is mounted inside the bushing together with the steel balls and sealed with a retaining ring from one side or both sides of the linear bushing.

Long Square Flange Linear Bearing KBK-L Features

The outer bushing surface of KBK-L long square flange linear bearing is complete. There is not any outer stop grooves, and a square flange at one end of the bushing. The flange part is evenly distributed with four connection holes for fixing the entire bearing. The number of ball rows of KBK-L European metric series linear bearings supplied by ISUTAMI varies according to the bearing size, and ranges from 4 to 6 columns. 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 same with KB-L long linear bearing, KBF-L long circular linear bearing, KBFC-L long centered circular flange linear bearing, KBKC-L long centered square flange linear bearing. The specific parameters are shown in the table.

In addition, the diameter (D1) of KBK-L long square flange is larger than the diameter of the bushing, ranging from 25mm to 106 mm, which is consistent with KBK square flange linear bearing; the height of the flange (H) ranges from 5mm to18mm. This data is consistent with KBF circular flange linear bearing, KBF-L long circular flange linear bearing, KBK square flange linear bearing. Because it has a flange, the weight is bigger than KB-L of the same specification.

KBK-L long flange linear bearing has a square flange with a non-flanged linear bearing as a whole, and the corresponding module makes the shaft positioning simple. It does not need to be fixed in the matching bearing seat like the linear bearing. Therefore, it has become very economical, and the overall weight of the linear bearing assembly has been reduced, and the operation is smoother.

Unlike ball bearings, the basic static load rating of KBK-L long square flange linear bearing is greater than the basic dynamic load rating, and as the size increases, this value gap is even larger, even three 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, fans, pulleys, rollers, In transmission equipment, entertainment equipment, robots, medical equipment and other products.
