Fan seat and method for producing it

Abstract

A fan seat (30, 30′) includes a basis (31) with a vertical extending tubal portion (32) having a pair of flanges (33) integrally formed on opposite ends of an inner circumferential surface thereof, and a bearing set (34, 34′) located in the tubal portion and sandwiched between the flanges. The bearing set includes a tube (36) and a pair of bearings (38) firmly secured in opposite ends of the tube. A method for producing the fan seat includes the following steps: providing a mold (50) with a cavity (53), locating the bearing set in the cavity with a space (60) formed between the bearing set and the mold corresponding to the tubal portion, injecting molten material into the space, and cooling the molten material whereby the molten material congeals into the tubal portion and integrates with the tube.
