Sweeney Single Pulley Diamond Sheaves
Discover our range precision engineered heavy duty single pulley diamond sheaves designed specifically for demanding jobs like those found in the entertainment and other specialty industries. Our exceptional selection includes sizes ranging from the compact 3/64 in. to the large 1/2 in. variants. We also offer a line of double and triple pulleys sheaves to meet your specific needs.
These versatile sheaves are utilized for a wide range of applications including rigging for special effects, stunts, theater, as well as industrial and scientific uses.
Crafted with precision, we mill the cheeks from 6061 T6 aluminum billet using our precision CNC machines. To prevent fouling and to keep the sheaves as low profile as possible the pulleys are recessed within the cheeks.
Our sheaves are equipped with shielded single row ball bearings for the 3/64' and 3/32' sizes, while the 1/8' diamond sheaves feature precision metric sealed single row ball bearings. For all other pulleys, we utilize precision metric double row sealed ball bearings.
To ensure our sheaves are the most dependable and durable in the industry, all fasteners are either stainless or alloy steel. Our sheaves are built to withstand the demands of any project.
In the entertainment industry, we know how important sound is. We've designed our sheaves to remain completely silent during operation, setting them apart from many marine, industrial, and rock climbing sheaves. Even the most discerning sound professionals will appreciate their noiseless performance.
As a testament to their durability, all of our sheave sizes have undergone rigorous destructive testing, with the cable breaking before any damage occurred to the sheave itself. Featuring CNC milled and black type II anodized cheeks, along with stainless or alloy steel fasteners, our sheaves are built to withstand the demands of any project.
The Tiny 3/64 inch sheaves and shackles are used for miniatures and hidden small rigging. Pulleys in our 3/64 inch sheaves turn on a shielded precision ball bearing for maximum smoothness and quietness.
