Product highlights 3M 12T timing pulley: 3M-series pulley with 12 teeth for precise engagement with 3M timing belts — reliable tooth contact for accurate motion transfer. 60T 1:5 pulley: 60-tooth synchronous pulley providing a 1:5 reduction ratio to reduce output speed while increasing available torque. Synchronous wheel drive: Positive, slip-free belt interface that maintains phase and timing between driven components for repeatable performance. Reduction bandwidth 10: Rated at 10 to deliver controlled response in compact drive systems where stable reduction and predictable behavior matter. Mounting and compatibility: Timing belt holes in Ø5, Ø6, Ø8, and Ø10 mm to accommodate common mounting hardware; compatible with 6 mm shafts, 12T configurations, 12 mm bores, and 60T pulleys. Key benefits — why you need this Accurate, repeatable motion: Positive tooth engagement minimizes backlash and slip, improving positional accuracy in indexing and positioning applications. Increased torque without extra space: The 1:5 reduction with a 60T pulley lets you trade speed for torque in tight assemblies without oversized components. Flexible mounting: Multiple hole sizes (5, 6, 8, 10 mm) and compatibility with common shaft and bore sizes reduce custom machining and simplify installation. Predictable performance: The synchronous design and rated reduction bandwidth provide consistent timing and control across start/stop cycles and variable loads. Function and important attributes Function: Transfers rotary motion using a 3M timing belt and matched pulleys to produce synchronized, slip-free drive between shafted components. Compatibility: 3M-series belts and pulleys; fits 12T configurations and interfaces with 60T pulleys; mounting holes Ø5/Ø6/Ø8/Ø10 mm; compatible with 6 mm shafts and 12 mm bore requirements as specified. Size and fit: 12-tooth driver pulley and 60-tooth reduction pulley (1:5) — choose the assembly for compact gear reduction needs. Performance: Positive engagement for high repeatability, and reduction bandwidth rated at 10 for controlled behavior in compact drives. Typical applications Industrial automation: Drive small axes on robotic arms, indexing tables, or pick-and-place stations where precise timing and repeatable torque are required. 3D printing and CNC: Stabilize X/Y or Z axis motion with a synchronized belt drive to reduce layer registration errors and improve print or cut accuracy. Packaging and light conveying: Implement compact, controlled-speed belt drives on small conveyors or product feeders to maintain consistent throughput and gentle handling. Installation notes Confirm shaft and bore sizes before assembly: compatible options include 6 mm shafts and 12 mm bores where indicated. Match to 3M-series timing belt and ensure correct belt tension for optimal tooth engagement and long service life. Use the supplied hole sizes (Ø5, Ø6, Ø8, Ø10 mm) to select appropriate fasteners or bushings for mounting and alignment. This pulley set provides a compact, slip-free, and compatible solution when you need precise timing, increased torque via reduction, and flexible mounting options for small drive systems.
