Thomson Nyliner plastic flange bearings offer more retention capability than a traditional sleeve bearing for applications where radial and/ or axial loads are expected. Other features of Thomson Nyliner plastic flange bearings include anti-rotation keys that eliminate both linear and rotational motion and lack of fluctuation. Thin wall construction of these bearings assures that they hold up in demanding applications. Also, like straight sleeve bearings, these plastic flange bearings feature the standard axial compensation gap to accommodate changes in temperature and humidity.
Flanges permit our bearings to take both axial and radial loads, while providing more secure retention than plain sleeve types. The anti-rotation key featured on our plastic flanged bearing minimizes axial motion. Select plastic flanged bearings are available in Thomson Nyliner high-performance polymer.
The minimum diametral shaft to bearing clearance normally recommended for flanged bearings is .001˝ for bearing I.D. sizes from 1.000˝ to 1.250˝; and .002˝ for I.D. sizes from 1.250˝ to 1.500˝.
These clearances are recommended to allow proper running clearance for trouble-free operation. Bearings will expand slightly due to frictional heat and moisture absorption. The majority of this expansion is accommodated by the compensation gap. Changes in wall thickness are minimal due to the thin wall construction of Thomson Nyliner bearings.
