Open Linear Bearing SW-OP

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

The bushing and steel ball of SW-OP open type linear bearing is 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.

Open Linear Bearing SW-OP Features

The outer bushing of SW-OP open linear bearing is an open type, and the opening distance (h1) and the opening angle (θ) vary according to each item. The number of ball rows for SW-OP inch series open type supplied by ISUTAMI is 3-5 columns. Among them, the number of ball rows for SW16OP steel retainer is 4 columns, and the number of rows for engineering plastic retainers is 5 columns;

The inner diameter (dr) ranges from 1/2''-2'', and the inner diameter tolerance range is mainly divided into three ranges: -0.009~0mm, -0.010~0mm, -0.012~0mm;
The outer diameter (D) range is 0.875''-3'', and the outer diameter tolerance range is mainly divided into four ranges: -0.013~0mm, -0.016~0mm, -0.019~0mm, -0.022~0mm;
The length (L) range is 1.25''-4'', and the length tolerance range is mainly divided into -0.2 to 0 mm and -0.3 to 0 mm;
The opening distance (h1) ranges from 0.34''-1";
The opening angle (θ) ranges from 50°to 80°;
The maximum radial eccentricity is divided into four grades: 0.012mm, 0.015mm, 0.02mm and 0.025mm ;
The basic dynamic load rating (C) ranges from 52 to 390 kgf (basic rated life is 50 km);
The basic static load (Co) range is 80-810kgf (basic rated life is 50km).

The biggest difference between SW-OP open linear bearing and SW standard type linear bearing is that the former bushing is open and suitable for the corresponding shaft support rail.

SW-OP open type linear bearing is matched with SWD open type linear bearing pillow block, SWD-L long type open linear bearing pillow block, SWB-OP open type linear bearing pillow block, SWB-L-OP long type open linear bearing pillow block, and can be replaced by SSW super open type linear bearings.
