Ronstan, Series 40 Ball Bearing Orbit Cheek Block, RF48151

Description

The new Series 40 ball bearing Orbit Blocks™ provide the perfect balance of strength, performance, and reliability. They offer class-leading dynamic and static load ratings, the highest available in this size of performance blocks. Lightweight and strong toughened glass fibre reinforced nylon cheeks replace stainless steel straps used in traditional utility blocks, offering the perfect balance of performance and reliability.

The sheave incorporates our 2-stage bearing system using ball bearings to minimize friction and a secondary full-contact bearing to maintain low friction across the full working load range.

Applications include mainsheet systems and spinnaker sheets on dinghies, off-the-beach catamarans, and sportsboats up to 8m (26ft), as well as halyard, vang, and backstay applications on boats up to 9m (30ft). It is also suitable for control line applications on larger yachts.
