Type 6 With Anti Rotation Key 20L20-FK
Flanges permit Types 5 and 6 Thomson Nyliner bearings to take both axial and radial loads, while providing more secure retention than plain sleeve types.
Clearances. The minimum diametral shaft to bearing clearance normally recommended for Types 5 and 6 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.
