Bearing Cage Manufacturing Process

At Ilene Industries, Inc., we pride ourselves in being the leader for bearing cage manufacturers. We service many industries with our top notch products.

About This Custom Order

Our experienced bearing cages manufacturers formed this steel bearing retainer cage for a customer in the wind power generation industry. During our bearing cage manufacturing process, we applied several processes including machining, forming, and welding.

After deburring the part, our bearing cage manufacturer performed a close inspection to ensure the highest level of quality.

With exacting attention to detail, our bearing cages manufacturers maintained tolerances of 0.010″. Made from HRPO, CQ temper, and RB75 max, the part had a thickness of .190″, width of 1.875″, and a ball pocket diameter of 1.250″.

The 8′ diameter cages were some of the largest diameter cages we have produced to date. The final step in our bearing cage manufacturing process was the parts being individually padded, oiled, and packaged in custom wood built crates.

Our bearing cage manufacturer delivered 25 bearing retainer cages to the Michigan based customer within six weeks of the original order.
