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 sections Slightly 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 processing This initial machining operation is usually done in a lathe and the diameter is turned within 0.15mm 鈥?0.20mm larger than the finish diameter of the pin. 3. End Grinding Pins can have a variety of end shapes, including straight, deburred, pointed, spherical, chamfered, or even a unique design. 4. Harden by heat treatment Pins are processed through a continuous furnace with atmospheric protection, and quenched in oil. 5. Centerless Grinding This 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. Inspection Finally, after the manufacturing process is complete each pin will be carefully and strictly checked to guaranteeing perfect quality. If you would like to learn more about our precision pins, our rollers, customized bearing assemblies or any of the other products, we invite you to contact us soon. Production Market Since 2008 we exported our pins and rollers to Europe market. Our company mainly produces high requirements products, fast delivery and good quality make Shengwang the ideal supplier for mission-critical components.Motorcycle Crank Pin manufacturers website:http://www.component-manufacturer.com/
