Pulleys & Blocks

Ronstan offers a large variety of pulley blocks with maximum working loads from 150kg to 15,000kg and sheave diameters ranging from 15mm to 200mm. The two primary bearing types we offer are All Purpose (AP) and Ball Bearing (BB) pulley blocks. All Purpose blocks are designed for high static working loads and are virtually maintenance free. Ball Bearing blocks are very efficient and reduce friction in purchase systems.

Our pulley blocks are available as sheaves only, or in single, double, and triple arrangements and can be supplied for use with wire or fibre rope. Blocks can be combined in pairs to provide purchase systems (also known as block and tackle), which can be supplied as components or complete systems including rope.
