ABSTRACT:
A needle bar pendulum for a sewing machine comprises a carrier bar which has a bearing engagement end at each end which are terminated by a shoulder in a central portion of the carrier bar and separate bearing members are engaged over each end of the carrier bar. For this purpose the bearing members have bores therethrough for accommodating the respective ends of the carrier bar and they also have a bore therethrough for the needle bar. The bearings are advantageously joined to the carrier bar in a permanent manner such as by a cementing or welding of the bearings in position after they are engaged thereon.
