Pulley for use in e.g. crane, has bearing that exhibits pulley as single integral component by overmolding or recasting bearing that is inserted into socket, and extending bore introducing lubricant radially down to bearing

摘要

The pulley has a bearing (7) i.e. roller bearing, that exhibits the pulley as a single integral component by overmolding or recasting the bearing, where pulley is made of plastic material (12) e.g. polyamide such as Cast Nylon 6, Natural. The bearing is inserted into a socket (11) i.e. steel socket, that is surrounded by the plastic material. An extending bore (15) introduces a lubricant radially down to the bearing. A pulley body is pointed along circumferential direction of an extending groove (14) in which a wire rope is fed.
