摘要:
A hollow ball structure, for use in a ball bearing application, having two half shells constructed of powdered material made porous to absorb a lubricant therewithin to be automatically exuded onto the surface of the bearing and bearing races, and thereby provide a self-lubrication feature to the structure. The powdered ball bearing may be utilized in a bearing assembly in alternate relation with both solid and other types of hollow ball structures to thereby provide both strength, flexibility and lubrication.
摘要:
A hollow ball, or roller bearing structure fabricated from a pair of half shell members, each of which incorporates a heat sink for absorbing the heat developed during the operation of the bearing structure and thereby prolonging the bearing wear life capability.
