Whether you're a workshop owner maintaining a belt-driven lathe, a DIY builder assembling a custom conveyor, or a technician replacing worn drive components, finding a pulley that fits precisely and holds up under load is non-negotiable. These double V-groove aluminum drive pulleys are engineered for exactly that — a secure, repeatable fit with the dimensional accuracy that belt-driven systems demand.\u003c\/p\u003e\n\u003cp\u003eEach pulley is machined from aluminum alloy, offering a balance of low rotating mass and structural rigidity. The double V-groove profile is sized for O(Z)-section V-belts, with an outer diameter (OD) ranging from 32mm to 60mm (~1.26\" to 2.36\") and a large OD\/small OD step configuration of 40mm\/32mm, 50mm\/40mm, or 60mm\/50mm.
