Long Square Flange Linear Bearing LMK-L

Long Square Flange Linear Bearing LMK-L
ISUTAMI LMK-L long square flange linear bearing, also known as LMK-L long square flange linear ball bearing or LMK-L long square flange linear bushing bearing. LM is the code name of the Asian standard series in linear bearings, K is the meaning of square flange, and L is the abbreviation of Long, this series is suitable for Asian markets using metric units, such as Japan, Korea, and Singapore, etc.

LMK-L linear bearing bushing and steel balls are made of hard bearing steel. The ball retainer is made of bearing steel, stainless steel or POM material, and the buckle (sealing ring) (usually represented by U or P), is made of NBR. The ball retainer is mounted inside the bushing together with the steel balls and is sealed from one or both sides of the bushing with a retaining ring.

Long Square Flange Linear Bearing LMK-L Features

The outer bushing surface of LMK-L linear bearing is a complete one. There is no outer stop groove. And there is a chamfered square flange at one end of the bushing.4 circular connecting holes are evenly distributed near the four corners, for fixing the entire bearing. The LMK-L Asian series supplied by ISUTAMI: The number of ball rows inside bushing varies according to the 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 same as the same specification of LMF-L long circular flange linear bearing, LMFC-L long centered circular flange linear bearing, LMKC-L long centered square flange linear bearing, LMFP-L long pilot pattern  circular flange linear bearings, LMKP-L long pilot pattern square flange bearings, the specific parameters are shown in the table.

In addition, the LMK-L square flange length (K) is larger than the diameter of the bushing, its range is 22-106mm, which is consistent with LMK square flange linear bearing; the height (H) of the flange is 5-18mm, this data is consistent with the LMK linear bearing, LMF circular flange  linear bearing, LMF-L long circular flange linear bearing and other flange series linear bearings. LMK-L linear bearing, its basic static load rating is greater than the basic dynamic load rating, and as the size increases, this value gap continues to widen, up to 3 times the maximum.

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.
