Long Circular Flange Linear Bearing SWF-L

Long Circular Flange Linear Bearing SWF-L
ISUTAMI SWF-L long type circular flange linear bearings, also known as SWF-L long type circular flange linear ball bearings or SWF-L long type circular flange linear bushing bearings. SW is the code name of the inch series in linear bearings, F is the abbreviation of the circular 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 bushing and steel balls of SWF-L long and circular flange type linear bearing are made of 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 with the steel balls and sealed with a retaining ring from one side or both sides of the linear bushing.

Long Circular Flange Linear Bearing SWF-L Features

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

In addition, the diameter of SWF-L circular flange is larger than the diameter of the bushing, ranging from 1.25'' to 4.375''; the height of the flange is 0.219''-0.5'', this data is consistent with the SWF circular flange linear bearing and SWK square flange linear bearing.

SWF-L extended circular flange linear bearing has a flange part with a fixed bearing as a whole, and the corresponding model parts make the axial positioning simple. It does not need to be fixed in the matching bearing seat like the linear bearing. So it makes economic as well as reduces the overall weight of the linear bearing assembly.
