Thomson Nyliner™ Flanged Bearings

Standard
Standard With Anti-Rotation Key

Plastic flange bearings are designed to support heavy loads when the shaft axis is perpendicular to the application's mounting surface. Thomson Nyliner plastic flange bearings offer more secure retention for radial and axial loads than a standard sleeve bearing.
The thin wall construction of these bearings ensures they hold up in applications with high speed and low coefficient of friction. Similar to straight sleeve bearings, our plastic flange bearings accommodate changes in temperature and humidity with a standard axial compensation gap.
Our flange mount bearings are also designed with anti-rotation keys. This feature eliminates both linear and rotational motion and lack of fluctuation. Select nylon bearings are available in Thomson Nyliner high-performance polymer bearing material.

Clearances

The minimum diametral shaft to bearing clearance normally recommended for flange 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. Plastic 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.
