Square Flange Linear Bearing SWK

Square Flange Linear Bearing SWK
ISUTAMI SWK square flange linear bearings, also known as SWK square flange linear ball bearings or SWK square flange linear bushing bearings. SW is the code name of the inch series for linear bearings, K is the abbreviation of the square flange, mainly applicable to the market of British units, such as the United Kingdom and the Commonwealth.

The bushing and steel balls of SWK square flange linear bearing are made of high carbon bearing steel, the ball retainer is made of metal steel, stainless steel or POM resin, and the sealing ring, usually represented by U or P, is made of NBR.  The ball retainer is installed inside the linear bushing together with the steel ball and is sealed from both sides of the bushing by sealing rings.

Square Flange Linear Bearing SWK Features

The outer bushing surface of SWK series is completely seamless and has no external retaining groove. There is a square flange at one end of the bushing, and four circles are evenly distributed on the flange near the four corner regions. A connecting hole for fixing the entire bearing. The SWK inch series method supplied by ISUTAMI The number of ball rows of the blue linear bearing varies according to the bearing size and ranges from 4-6 columns. Among them, SWK16 steel retainer ball row number is 5 columns, POM 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, The maximum radial eccentricity, basic dynamic load rating (C) range, basic static load (Co) range and other data are consistent with SWF circular flange type linear bearings, SW standard linear bearings and SW-AJ adjustment type linear bearings. Please see the table for specific parameters.

In addition, the outer length of the flange side of SWK linear bearing length ranges from 1'' to 3.5''; the height of the flange ranges from 0.219'' to 0.5''. As it has a flange, the weight is larger than SW standard linear bearing of same specification but smaller than the SWF circular flange type linear bearing of the same specification.

The SWK linear bearing has a square flange, which is matched with the corresponding module components to make the axial positioning simple. It does not need to be installed in the matching bearing housing like the linear bearing, so it becomes very economical, also reduces the overall weight of the linear bearing assembly.
