AI Overview
Key Features and Types
- Material: High-strength steel or alloy steel for maximum durability.
- Applications: Crown blocks, traveling blocks, mud pumps, and wireline trucks.
- Design: Often features hardened grooves, API-compliant profiles for wire rope support, and sometimes steel-rubber composites.
- Bearings: High-load, often sealed and maintenance-free, such as the Sheave Pac bearing assembly for oil & gas drilling rigs from Timken.
Key Considerations
- Wear Resistance: Sheaves must resist abrasive wire rope movement under high tension.
- Load Limit: Certified rigging professionals must determine total load capacity, with smaller sheaves holding 400 to 2,000 lbs, but larger blocks supporting much more.
- Alignment: Proper installation is critical to prevent side pull and premature wire failure.
For sourcing and specific configurations, providers offer customized solutions, including various options for sheaves for oil drilling rigs on Alibaba.

What is the difference between a block and a sheave?
Blocks and Sheaves
A block is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift or pull heavy loads. A sheave is a pulley with a grooved wheel for holding a belt, wire rope, or rope. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power.
