Flanged Cylindrical Bushing with Stainless Steel Bushing and Knurled Mid Section

Knurl OD below the lower interference limit reduces the press-fit retention force and allows the bushing to spin in the housing bore under cyclic torque load before fretting fatigue initiates at the knurl-to-housing contact. Foshan Zhengshang Precision Hardware (Foshan, Guangdong, ISO 9001, ISO 14001, ISO 45001 certified) turns this flanged stainless steel bushing with knurled mid-section at their 2,500 m² of production area Foshan facility using Swiss machining and milling & turning, with bore-to-OD concentricity, knurl OD, and flange face perpendicularity inspected to match your drawing during initial part approval. Zhengshang serves automotive, medical equipment, drones, energy storage, and fastener stainless steel bushing applications. Provide bore-to-OD concentricity, knurl OD, flange perpendicularity, and stainless grade to get a quotation from our Foshan office and your drawing for quoting.
