Abstract

1481861 Bearings CANON KK and CANON SEIKI KK 19 July 1974 [20 July 1973] 32129/74 Heading F2A [Also in Division H2] A bearing housing for use in a D.C. motor which has a rotor 10 having a single shaft 9 rotatably mounted in and wholly supported by bearings 7, 8 attached to one side wall only of a casing 1, comprises a generally tubular portion 6 which is stepped at one end so as to facilitate fixing to the casing. Two bearings may be supported in the housing, one adjacent the casing of the motor and the other remote from the casing.
