Details

Silicon Iron Bronze, commonly known as AMS 4616, is an excellent source for anti-friction bearing cages, races, and spacers. It’s a special high strength silicon bronze with additional iron content that provides added strength in conjunction with the self lubricant of the silicon for excellent bearing and load properties.

We stock solid bar from 5/8″ to 4 1/2″ and machine blanks from 4 1/2″ to 18″.

We also produce finished machined retainers:
