Product specifications Models and shaft sizes: A1:10 — 6 mm input shaft and 6 mm output shaft B-1:10 — 8 mm input shaft and 8 mm output shaft C1:20 — 6 mm input shaft and 6 mm output shaft D1:20 — 8 mm input shaft and 8 mm output shaft Worm material: 45 mm steel, blackened Worm wheel material: copper Number of worm heads / available gear ratios: 1 worm head — gear ratio 1:20 2 worm heads — gear ratio 1:10 Bevel gear manufacturing: cast using advanced production technology; precise dimensions, complete and secure tooth engagement, stable transmission ratio Key benefits — why this product solves problems Precise fit and reliable performance: clearly defined shaft sizes and precision-cast bevel gears ensure accurate alignment and stable gear ratios for repeatable motion and torque transfer. Durable material combination: steel worm and copper worm wheel provide a robust contact pair for long service life while maintaining consistent engagement. Flexible configuration: multiple models and two worm-head/ratio options let you select the correct size and reduction for compact gearboxes, actuators, or drive assemblies. Reduced installation uncertainty: standard shaft diameters (6 mm and 8 mm) match common motor and gearbox interfaces to simplify integration. Function and compatibility Designed for compact worm-and-bevel gear transmission where right-angle or in-line shaft connections and speed reduction are required. Compatible with systems that accept 6 mm or 8 mm input/output shafts and that require 1:10 or 1:20 reductions delivered by single- or double-thread worm configurations. Precision casting and finished tooth geometry ensure stable operation across repeated cycles. Performance highlights Stable gear ratio: precision casting and robust tooth engagement minimize backlash and variation in reduction. Consistent meshing: the steel-to-copper gear pair balances strength and wear characteristics for predictable service life. Multiple configurations: choose A1, B-1, C1, or D1 to match the required shaft sizes and reduction ratio for your assembly. Typical applications Small gearboxes and right-angle drive assemblies in industrial automation where compact, reliable reduction is required. Valve actuators or positioning mechanisms that need precise, stable motion with standard 6 mm or 8 mm shaft interfaces. Low- to medium-speed conveyor drives, robotics joints, or instrumentation drives that benefit from compact worm/bevel gear reduction and long-lasting tooth engagement. What to consider when ordering Select the correct model number (A1, B-1, C1, D1) to match the required input and output shaft diameters. Choose the worm-head option corresponding to the desired gear ratio: 1 head for 1:20, 2 heads for 1:10. Verify compatibility of the 45 mm steel (blackened) worm and copper worm wheel materials with your operating environment and lubrication plan. Specifications summary Models: A1:10, B-1:10, C1:20, D1:20 Shaft sizes: 6 mm or 8 mm as specified per model Materials: worm — 45 mm steel, blackened; worm wheel — copper Worm heads / gear ratios: 1 (1:20) or 2 (1:10) Manufacturing: precision-cast bevel gear with accurate dimensions and secure tooth engagement
