Double Flanged Snap In Bearings

Types 7 and 8 snap-in Thomson Nyliner bearings are designed for easy installation in thin plates. Their double-flange construction assures positive bearing retention. The larger of the two flanges has sufficient area to take thrust loads.

Clearances. The minimum diametral shaft to bearing clearance normally recommended for Types 7 and 8 bearings is .001˝. 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.

Installation. The bearings’ compensation gap allows Types 7 and 8 bearings to be collapsed so the smaller flange can be easily spiralled through the mounting hole. Snap-in installation is fast and economical. During installation, the bearing is located over the hole with the gap facing up. Light finger pressure exerted to the left of the compensation gap spirals the bearing into position.
