Overview
The Dodge 118211 is a precision-engineered taper-lock sheave designed for mechanical power transmission applications. This Type A1 sheave accommodates A and B cross-section V-belts and features a versatile 1/2″ to 1-1/4″ bore range via the 1210 taper-lock bushing, making it suitable for multiple shaft diameters without requiring different pulleys.
Key Features
- Taper-Lock Bushing System: Slide the sheave taper bore into position over the mating tapered bushing surface and align unthreaded holes with threaded bushing holes for quick installation and removal
- Cast Iron Construction: Manufactured in plants certified to ISO 9002 quality standards, ensuring durability and precision
- Dual Belt Compatibility: Accepts both A and B cross-section V-belts in a single sheave body
- No Lubrication Required: Do not lubricate the bushing taper, hub taper, bushing bore or the shaft, and do not use lubricants — maintenance-free operation
- ISO 9002 Certified Manufacturing: Manufactured under strict quality control assurances with precision machining to exceed extended belt life requirements
