Barton Marine 35mm Diameter Plain Bearing Sheave

The Barton Marine 35mm Diameter Plain Bearing Sheave is a replacement rope sheave engineered for demanding marine applications where reliability and longevity are non-negotiable. Used throughout Barton's complete block range, this sheave is the workhorse component that keeps your halyards, sheets, and control lines running smoothly whether you're sailing coastal waters or working a commercial vessel. Anyone who has spent time on the water knows that a seized or worn sheave creates friction, binding, and dangerous load transfer—problems that cascade into safety risks and maintenance headaches.

Constructed from UV-resistant acetal resin, the Barton Marine sheave resists the relentless assault of saltwater, UV radiation, and extreme temperature fluctuations that degrade lesser materials. The plain bearing design eliminates the failure points common in ball-bearing sheaves—no grease migration, no corrosion-induced seizing—and the molded construction ensures uniform wall thickness and precise rope-groove geometry. At just 1 pound, it's light enough for overhead installation yet robust enough to handle repeated heavy-load cycling without deformation or creep, making it ideal for both standing rigging and running rigging applications across sailboats, workboats, and marine equipment.

Maintenance crews, riggers, and boat owners benefit most from keeping spare Barton Marine sheaves on hand, as the 35mm diameter fits seamlessly into existing Barton block assemblies and reduces downtime during refits or emergency repairs. The universal design works across multiple rope diameters and loads, making it a cost-effective replacement solution for anyone running Barton hardware on their vessel. Installation is straightforward—simply pin or bolt into place—and the sheave's proven track record in both leisure and professional maritime settings makes it a trusted upgrade component.
