Ronstan series 55 BB orbit block double becket swivel Sailing

55 Series BB Orbital Block, Double Becket Swivel

Lightweight

Kilogram for one kilogram of workload , BB and RT Orbit Blocks™ are the lightest in the world. The unique orbital design allows the bearing to be located only in the active areas of the floating pulley. This minimizes the mass of the inactive return ring and the hub.

Weight and bulk are further reduced in the different block configurations. The single ball bearing block and the becket block have a through becket arrangement. The result? The lowest weight possible.

Multi-sheave pulleys have only one intermediate cheek and an ultra-light and efficient head arrangement. This gives a 30% weight advantage over the nearest competitor. Other brands simply connect their individual blocks. This results in unnecessary double cheeks between each sheave, held togethere by a heavy steel channel on the top of the block.

Highest working load in its class

The orbital ball bearing arrangement provides the largest possible bearing ring diameter. This maximizes charging performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a full contact secondary bearing. This achieves minimum friction over the entire working load range.

The floating pulley and bearing system are supported by a fiber reinforced load frame. The design was computer modeled to optimize constraints. The Dyneema Link is produced from FSE Robline SK75 fiber, which is 10 times stronger and lighter than steel and provides the final connection of the block to the load point.
