Long Linear Bearing SW-L

Long Linear Bearing SW-L
ISUTAMI SW-L long linear bearings, also known as SW-L long linear ball bearings or SW-L long linear bushing bearings. SW is the code name for the imperial series, L is short for long, mainly used in the markets of the UK and other British Commonwealth of Nations.

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

Long Linear Bearing SW-L Features

The outer bushing surface of SW-L extended linear bearing is completely seamless and there is two stop groove for fixing the bearing bushing . SW-L inch series extended linear bearing supplied by ISUTAMI:
The number of ball column ranges from 3-6. Especially, the number of rows for item SW16L steel retainer is 5 columns, and for engineering plastic retainer is 6 columns;

The inner diameter (dr) range is 1/4''-2'', and the diameter tolerance range varies with the inner diameter, mainly divided into three intervals of -0.011~0mm, -0.012~0mm, -0.015~0mm;
The outer diameter (D) range is 1/2''-3'', and the diameter tolerance range varies with the outer diameter, mainly divided into five intervals: -0.013~0mm, -0.016~0mm, -0.019~0mm, -0.022 ~0mm, -0.025~0mm ;
The length (L) range is 1.375''-7.75'', and tolerance range varies with length, mainly divided into two intervals of -0.3~0mm and -0.4~0mm;
The maximum radial eccentricity is divided into four grades according to different sizes: 0.015mm, 0.02mm, 0.025mm and 0.03mm ;
The basic dynamic load rating (C) ranges from 33 to 620 kgf (basic rated life is 50 km);
The basic static load (Co) range is 54-1622kgf (basic rated life is 50km).
SW-L long type linear bearings are generally mounted to SW series linear bearing housings, with linear shafts, installed and used according to customer needs.
