Ronstan, Series 40 Ball Bearing Stand-Up Orbit Block™, RF48140

Description

The Series 40 Ball Bearing Orbit Blocks™ offer an exceptional balance of strength, performance, and reliability. These blocks feature class-leading dynamic and static load ratings, the highest available in this size category. The lightweight and robust design includes toughened glass fibre reinforced nylon cheeks, replacing traditional stainless steel straps, ensuring optimal performance and reliability.

The range includes single and double sheave lashing or soft attachment options, as well as multiple sheave blocks, accommodating systems up to a 12:1 purchase mainsheet system for off-the-beach performance catamarans. These blocks are equipped with our carbon reinforced C-Cleat™ for secure rope holding and adjustable stainless steel cleat arms for preferred cleating angles.

The ball bearing versions incorporate a 2-stage bearing system to minimize friction, while high load versions are designed for applications with high dynamic or static loads, featuring a high strength grade 2205 stainless steel sheave and hub.

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 8m (26ft), and control line applications on larger yachts.
