Hangzhou Unibear Industrial Co. Ltd|Hangzhou Unibear Holding Group Co. Ltd-Motorcycle Sprocket

Motorcycle Sprocket
- Innovatively researching and developing the “Once Punch Forming” technology for sprocket teeth shape.
- Fit clearance between chain roller and sprocket teeth arc≤0.05mm, superior to domestic competitors(0.3-0.5mm) by 80%, without noise during meshing operation.
- Processing by Japan-imported slow-feeding wire-cutting machine for teeth punching mould, with advanced punching technique, teeth arc roughness≤1.6μm, 50% lower than domestic competitors’ roughness(≤3.2μm) produced with traditional gear hobbing tec
- Heat treatment by automatic mesh belt conveyor furnace, teeth surface hardness reaching 56-62HRC, using imported high-tech grease, increasing wear-resistance by 50%, 30,000 km guaranteed.
- Advanced “Once Punch Forming” technology, ensuring concentricity between teeth panel and central hole≤0.05mm, rolling teeth≤0.2mm, greatly increasing meshing stability between chain and sprocket, preventing chain bouncing and noise occurred.
- Surface centerless grind and shot-peening technique, refining inner microstructure, increasing surface hardness.
- Surface stoving varnish technique, such as red, yellow, orange, green, blue, black, etc. meeting various appearance demands.
