Aluminum timing belt pulleys are used to precisely synchronize rotational motion between components, such as in automotive engines and industrial machinery. They feature a toothed profile designed to mesh with a specific timing belt, ensuring accurate power transmission and preventing slippage.
aluminum timing belt pulleys Detail
| Product Name | Aluminum timing belt pulleys | 
| Product Material | Made of aluminum alloy, common aluminum alloy grades include 6061, 6063, etc. They have the characteristics of light weight, corrosion resistance, and good heat dissipation performance. | 
| Product Process | Precision machining: select high-quality aluminum alloy ingots, anneal to eliminate stress, CNC turn the outer circle and end face, bore the reference hole, and then rough and fine roll the gear to form the tooth shape. After aging treatment to stabilize the structure, grind the tooth surface and reference surface to ensure accuracy. | 
| Surface Treatment | Options include anodizing, conductive oxidation, chemical nickel plating, hard coating spraying, sandblasting and passivation. | 
| Customizable Products | Gears / Sprockets / Worms / Shafts / Rack Bars / Bevel Gears, etc. |
