Nylon Bearing Cage Injection Molding Parts

As a core component for positioning and isolating rolling elements, this ring-shaped structure guides needles or rollers to operate smoothly through evenly distributed window holes. Its design focuses on maintaining equal spacing between rolling elements to prevent mutual collision and frictional heating during high-speed rotation. It is commonly used inside deep groove ball bearings, cylindrical roller bearings, and thrust bearings.

Such parts are mostly manufactured using modified engineering plastics like PA66 via injection molding. The process demands strict control over mold cavity finish and injection parameters to ensure burr-free window edges and high positional consistency. The material must offer excellent wear resistance, self-lubrication, and dimensional stability to meet long-term service requirements under frequent start-stop or heavy-load conditions.

Jiaxing Yiteng Intelligent Technology holds IATF16949 certification and is equipped with injection molding machines from brands such as Shuangsheng and Sumitomo, along with Zeiss coordinate measuring machines (CMM). Our annual comprehensive production capacity reaches 200 million units. The factory possesses full-chain control capabilities from raw material moisture treatment to finished product visual sorting, undertaking custom processing for various non-standard bearing cages to ensure dimensional consistency in batch deliveries.
