Huddersfield Bearings Ltd

self lubricating units consist of a double sealed single row deep groove ball bearing and any one of cast iron, synthetic rubber or pressed steel housings of various configurations. the self contained bearing with spherical ground outside diameter is assembled into a corresponding spherical seat of the housing, providing full self alignment of the bearing in the housing at mounting. set-screw locking which is shown in sectional view below is a popular method of mounting to the shaft. Adapter sleeve and eccentric locking collar are also available. For services under more severe operating conditions, bearing units with cast iron covers and pressed steel covers are available as standard types. for set-screw locking types, the inner ring of the self-contained bearing is hardened in the raceway and surrounding parts where hardening is necessary, while the extended part where the set-screws are installed is left metallurgically mild and tenacious. This special heat-treatment ensures full bearing performance and prevents the set-screw from loosening during operation, as the set-screws can be tightened hard enough without causing destructive inner ring cracking.
