Square Flange Linear Bearing LMK

Square Flange Linear Bearing LMK
ISUTAMI LMK square flange linear bearings, also known as LMK square flange linear ball bearings or LMK square flange linear bushing bearings. LM is the code name for the Asian standard series in linear bearings, and K means square. This model is suitable for Asian markets using metric units in Japan, Korea, Singapore, etc.

LMK square flange linear bearing bushing and steel ball are made of high carbon bearing steel. The ball retainer is made of metal steel, stainless steel or POM material. The sealing ring, usually represented by U or P, is made of NBR.

Square Flange Linear Bearing LMK Features

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 bushing.

LMK square flange linear bearing has a complete and seamless bushing surface with no external stop groove. There is a square flange at one end of the bushing. Four circular connecting holes are evenly distributed around the four corners of the flange, to fix the bearing. The number of ball rows of the LMK Asian 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. The data is basically the same as LMF circular flange linear bearing, LM standard linear bearing and LM-AJ adjustment linear bearing. The specific parameters are shown in the table.

In addition, the MK square flange linear bearing flange length (K) is larger than the bushing diameter, the range is 22-106mm; the flange height (H) range is 5-18; because of the flange, the weight is better than The LM standard linear bearing of the same specification is large.

LMK linear ball bearing has a chamfered square flange. With the corresponding module, the shaft positioning is simple, and it does not need to be installed in the matching bearing housing like a non-flange linear bearing. Therefore, it becomes very economical, and the overall weight of the linear bearing assembly is also reduced, the operation is smoother as well.

Unlike ball bearings, the basic static load rating of the LMK linear ball bearings is greater than the basic dynamic load rating, and as the size increases, this value gap continues to widen, 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, fans, pulleys, rollers, transmission equipment, entertainment equipment, robots, medical equipment and other products.
