VGroove Aluminum Pulleys for 6mm Width PU Round Belts — precision, durability, and easy installation Key benefits Reliable power transmission: Vgroove profile matched to PU round belts delivers consistent engagement and smooth motion for accurate speed and position control. Easy integration: Designed specifically for belts with a 6mm width, these pulleys fit common smallbelt systems without modification. Longlasting performance: CNCmachined aluminum alloy construction provides a precise profile, low friction, and corrosion resistance for dependable operation. Features Compatibility: Suited for PU round belts with a 6mm width. Outer diameters available from 20 mm to 80 mm to match different speed and torque requirements. Material and finish: Solid aluminum alloy body that balances light weight with strength; precision machining reduces vibration and wear. Precision manufacturing: CNC machining ensures accurate groove geometry and concentricity for smooth, quiet running and repeatable results. Secure mounting: Fixing grub screws are supplied for firm attachment to shafts, simplifying assembly and minimizing slippage. Performance: Engineered for smooth transmission and positional accuracy in small to mediumload applications. Typical applications Robotics and automation: Drive small actuators, timing stages, or robot joints where compact, accurate belt drives are needed. Small conveyors and material handling: Power lightduty conveyor belts or indexing systems for packaging, lab equipment, or assembly fixtures. DIY and prototyping: Ideal for 3D printer modifications, CNC hobby machines, and other maker projects that use PU round belts and require reliable pulleys. Installation notes Verify belt width (6 mm) and select the appropriate outer diameter (20–80 mm) to match belt wrap and pulley ratio. Slide pulley onto shaft, align with belt path, and tighten the supplied grub screws securely against the shaft without overtorquing. Check alignment and tension after installation to maximize belt life and ensure smooth operation.
