Ronstan Series 60 Core Block™ - Single - Becket

The Ronstan Series 60 Core Block – Single – Becket is a precision-engineered pulley block designed for demanding marine, automotive, and equipment rigging applications. Built for mechanics and fabricators who demand reliability under load, this single becket block represents the evolution of traditional pulley technology, combining smooth operation with robust load-handling capability across both static and dynamic working conditions. Whether you're installing recovery winches, engine hoist systems, or custom lifting solutions, this block delivers consistent performance in high-stress environments where failure isn't an option.

At the heart of the Ronstan Series 60 Core Block lies a tuned 2-stage bearing system that optimizes friction reduction across the entire working load spectrum. This dual-stage design integrates an internal thrust bearing feature, allowing the block to manage both radial and axial loads simultaneously—critical for installations where cables pull at angles or where dynamic shock loading occurs during winching operations. The compact 4 x 2 x 7 inch footprint and 0.8 lb weight make it suitable for weight-conscious applications like motorsports recovery or overhead rigging, while the becket attachment point (open-eye design) allows direct bolt or shackle integration into custom frames and mounting brackets without additional hardware complexity.

Mechanics installing custom winch systems, engine hoists, or load-handling equipment on trucks and fabrication rigs benefit most from this block's blend of durability and compact design. The becket configuration is ideal for fixed-point installations where the block remains stationary and the load moves through the pulley—standard for recovery winches, come-along rigging, and shop hoist applications. Installation requires only a secure mounting point rated for the intended working load; ensure all anchor bolts are fastened to the frame or structural member with appropriate Grade 8 fasteners and safety chains are used for redundancy on critical lifting tasks.
