Overview
The Dodge 118306 taper lock sheave is a precision-engineered pulley component for industrial power transmission systems. This two-groove sheave accommodates both A and B cross-section V-belts and features a taper lock bore design that provides superior torque transmission compared to quick-disconnect systems while reducing overhung load on associated equipment.
Key Features
- Taper-Lock Bore Design: Pound-for-pound torque capacity exceeds QD systems while reducing overhung load
- Dual-Groove Configuration: Two grooves with 3.78/4.16 inch pitch diameter accommodates multiple belt sizes
- Premium Cast Iron Construction: High-quality gray iron with corrosion-resistant finish
- ISO 9002 Certified Manufacturing: Manufactured in plants certified to ISO 9002 quality standards
- Extended Belt Life: Precision machining meets or exceeds RMA/MPTA industry standards for smooth operation
- Versatile Application Range: Suitable for standard and harsh duty applications at rim speeds up to 6500 FPM
