Barton Size 1 30mm Pulley

This Size 1 30mm plain bearing pulley block with swivel and becket provides a compact, low-weight rope handling solution for small craft. Its primary benefit is reliable line guidance with a manufacturer-rated safe working load of 355 kg and a break load of 710 kg.

Problem: on small boats you need dependable blocks that do not add unnecessary weight or complexity. Solution: this unit uses a plain bearing sheave and an internal steel frame to combine simplicity with structural strength for routine sail control and deck rigging.

• Sheave size 30 mm x 12 mm suitable for up to 8 mm (5/16") rope
• Manufacturer-rated SWL 355 kg (782 lbs) and break load 710 kg (1565 lbs)
• Internal steel frame for added strength and durability
• Single sheave with swivel head and becket for secure tailing or anchoring lines
• Lightweight compact dimensions 85 x 32 x 25 mm and weight 51 g for minimal deck load

Use cases: ideal for halyards, control lines, reefing systems and dinghy rigs where plain bearing performance is sufficient. Compared to ball bearing blocks this plain bearing option requires less maintenance and is lighter though it has a higher rolling resistance than ball bearing variants.
