Overview
The Dodge 2A6.2B6.6-1610 taper lock sheave (MPN 118227) is a precision-engineered power transmission component built for reliable belt-drive applications. This Type A1 sheave features a taper-lock bore design that accommodates bore sizes from 1/2″ to 1-11/16″, making it suitable for a wide range of shaft diameters. Cast iron construction ensures durability and longevity in demanding industrial environments.
Key Features
- Dual-groove design — optimized for A (4L) or B (5L) cross-section V-belts
