5TC Series Cast Iron Sheaves with Split Taper Bushings
5TC series five-groove sheaves are manufactured for C, CX, banded belts, and CC v-belts. They range from 7.40″ to 24.40″ in diameter. Depending on the sheave size, they are made to use Q2 taper bushings, which we also stock. Most 5TC sheaves are manufactured from a high-strength grade 35 cast iron, are phosphate-coated, and are painted for anti-corrosion. All of them are balanced at the factory for smooth machinery operation.
Overview of 5TC Series Cast Iron Sheaves with Split Taper Bushings
Engineered for heavy-duty industrial drives, 5TC series five-groove cast iron sheaves accommodate C, CX, CC, and banded V-belts. Our range includes pitch diameters from 7.40″ to 24.40″. Every sheave in this series utilizes standard Q2 split taper bushings, allowing quick installation and precise shaft positioning.
We manufacture 5TC sheaves from high-strength Grade 35 cast iron. Each pulley receives a phosphate coating and a durable paint finish to prevent corrosion and extend operational lifespan. Factory dynamic balancing ensures smooth, low-vibration performance on high-torque machinery.
Key Features & Performance Advantages
- Grade 35 Cast Iron Construction: Delivers high tensile strength, excellent heat dissipation, and superior wear resistance under heavy loads.
- Precise Q2 Bushing Fit: Enables simple mounting and dismounting while maintaining tight grip force on drive shafts.
- Multi-Groove Versatility: Fits C, CX, CC, and banded V-belts across diverse heavy equipment configurations.
- Corrosion Protection: Features a protective phosphate coating and anti-corrosion paint to withstand harsh industrial environments.
- Dynamic Factory Balancing: Eliminates drive vibration, protects motor bearings, and prolongs belt longevity.
