Manufacturing ProcessNeedle Bearing Pins and Rollers must be manufactured in such a way that optimizes performance and meet custom requirements. Read below to learn more about the steps involved in the manufacturing process of needle bearing pins and rollers. (The actual process of production will vary due to different product specification and customization requirements.)
1. Cut Wire to small sectionsSlightly oversized good quality wire is procured. Cutting the wire to the approximate same small sections is the first stage in the pin manufacturing process.
2. Rough processingThis initial machining operation is usually done in a lathe and the diameter is turned within 0.15mm — 0.20mm larger than the finish diameter of the pin.
3. End GrindingPins can have a variety of end shapes, including straight, deburred, pointed, spherical, chamfered, or even a unique design.
4. Harden by heat treatmentPins are processed through a continuous furnace with atmospheric protection, and quenched in oil.
5. Centerless GrindingThis is perhaps the most critical facet of the manufacturing process. It is through a precise setup and constant control that OD can be held within +/- 0.0015mm.
6. InspectionFinally, after the manufacturing process is complete each pin will be carefully and strictly checked to guaranteeing perfect quality.
