Ball Bearing Orbit Blocks™ boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and multiple attachment options.
Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets.
NOTE: This item is for the block only. To create the Laser Kicker arrangement as shown in the photo, you will need the following items in addition:
Product Code: 128459 Ronstan RF614 4.8mm Special Slotted Pin Bulb Shackle.
Product Code: 134304 RF9004-09 Dyneema® Soft Link.
Product Code: 106728 Rooster Whipping Twine (Black).
Product Code: 130794 Allen A.873 Bent Kicker Key - Laser®/Pico Kicker Key
Note: When using these accessories as a mounting option the breaking load is reduced to 1300kgs (2860lbs).
Kilogram for kilogram of working load BB Orbit Blocks™ are the world’s lightest. To gain peak performance, we engineered out the heavy steel load straps, head post, shackle and cleating accessories. Through extensive research and development, we replaced virtually all metal components with high-tech polymers and fibre equivalents.
Weight 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.
Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. Other brands just link together their single blocks with a heavy steel channel across the top of the block, with unnecessary extra cheeks adding extra weight and bulk not found in Ronstan Orbit Blocks™.
Highest working load in its class
The proven Ronstan 2-stage bearing system (Series 30 and larger) features high compression grade Acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.
The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods. The Dyneema® Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point.
