Ronstan Series 30 BB Orbit Block, Double
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.
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.
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
