Ronstan Series 30 BB Orbit Block, Single, Lashing Head, Becket Option
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.
Lightweight: Kilogram for kilogram of working load, Ball Bearing 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.
Highest working load in its class: 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. The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods.
Low profile and compact: The two way head in the single lashing block allows for alignment at 0° or 90° orientation.
Features:
- Lightweight.
- Highest working load in its class.
- Secure, versatile attachment.
- Ultra low profile thru-sheave becket.
- Low friction 2-stage ball bearing system provides consistent performance over the full working load range.
- SP versions feature a Nylatron sheave suitable for both rope and wire.
- Accepts RF1850S shackle in both orientations to create a conventional loop top block.
Materials:
- Sheave: High compression strength carbon black Acetal.
- Ball Bearings: High compression strength Acetal.
- Frame/Cheeks: Toughened, glass fibre reinforced Nylon.
- Link: UV stabilised, multi-strand impregnated SK75 Dyneema
