Long Square Flange Linear Bearing SWK-L

Long Square Flange Linear Bearing SWK-L
ISUTAMI SWK-L long type square flange linear bearings, also known as SWK-L long type square flange linear ball bearings or SWK-L long type square flange linear bushing bearings. SW is the code name of the inch series in linear bearings, K is the abbreviation of square flange, and L is short for long. It is mainly used in the market of British units such as the United Kingdom and the Commonwealth.

The material of bushing and steel balls of SWK-L long type square flange linear bearing is high carbon bearing steel. The ball retainer is made of metal steel, stainless steel or POM material. The sealing ring (usually shown by U Or P in the item), is made of NBR material. 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.

Long Square Flange Linear Bearing SWK-L Features

The outer bushing surface of SWK-L extended square flange linear bearing is whole. There is also no outer stop groove, and a square flange at one end of the bushing. In the flange part, there is evenly distributed four circles. Connection hole for fixing the entire bushing bearing. The number of ball rows of SWK-L inch series supplied by ISUTAMI varies according to bearing size, ranging 4-6 columns. Among them, SWF16L steel retainer ball row number is 5 columns, and engineering plastic retainer ball row number is 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 (Co) range and other data are similar as the same specification of SW-L long type linear bearings, SWF-L long type circular flange linear bearings, SWFC-L long centered circular flange linear bearings, SWKC-L long centered circular flange linear bearings, the specific parameters are shown in the table.

In addition, the length of SWK-L extended square flange linear bushing bearing is larger than the diameter of the bushing, ranging from 1'' to 3.5''; the height of the flange is 0.219''-0.5'', this data is consistent with SWF circular flange linear bearings, SWK square flange linear bearings.

Linear motion principle is the rolling friction. The bearing is in contact with the cylindrical shaft through the steel ball. The steel ball rotates with very small frictional resistance, so that high-precision smooth motion can be obtained, suitable for a low load with high speed.
