The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimises the mass of the inactive return race and hub.\u003c\/p\u003e\u003cp\u003eWeight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible.\u003c\/p\u003e\u003cp\u003eMulti-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eHighest working load in its class\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximises load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.\u003c\/p\u003e\u003cp\u003eThe floating sheave and bearing system is supported by a fibre-reinforced load frame.
