Circular Linear Bearing LMF

Circular Linear Bearing LMF
ISUTAMI LMF circular flange linear bearings, also known as LMF circular flange linear ball bearings or LMF circular flange linear bushing bearings. LM is the code name for the Asian standard series in linear bearings, and F is the meaning of circular flanges. This model is suitable for Asian markets using metric units in Japan, Korea, Singapore, etc.

The material of the bushing and steel ball for LMF circular flange type linear bearing is high carbon bearing steel. The ball retainer is made of metal steel, stainless steel or POM material, and the buckle, usually represented by U or P, is composed of NBR material. The ball retainer is mounted inside the bushing with the steel ball and sealed with a retaining ring from one side or both sides of the bushing.

Circular Linear Bearing LMF Features

LMF circular flange type linear bearing bushing surface is complete and seamless, there is no outer stop groove, and there is a circular flange at one end of the bushing, and four circular connecting holes are evenly distributed in the flange part for fixing bearing. The number of ball rows of the LM 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., are basically the same as the LMK square flange linear bearing, LM standard linear bearing and LM-AJ adjustment linear bearing. The specific parameters are shown in the table.

In addition, the LMF round flange type linear bearing flange diameter (D1) is larger than the bushing diameter, the range is 28-134mm; the flange height (H) range is 5-18; because of the flange, its weight is larger than LM standard linear bearing of the same specification.

LMF linear bearing with a fixed circular flange, with the corresponding module, the shaft positioning is simple, do not need to be installed in the matching bearing housing like a non-flange linear bearing. Therefore, it is very economical, and also reduces the overall weight of the linear bearing assembly and makes the operation smoother.

Unlike ball bearings, the basic static load rating of LMF 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, fans, pulleys, rollers, transmission equipment, entertainment equipment, robots, medical equipment and other products.
