Ronstan RF35101 Series 30 OrbitBlock

Ronstan Rf35101 Series 30 OrbitBlock single, lashing head and 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. 

The Ronstan two-stage bearing system feature 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. 

Suitable for mainsheets systems and spinnaker sheets on dinghies to 5m. Halyard, vang and backstay applications on boats to 5m and control line applications on larger yachts. 

High compression strength carbon black Acetal sheaves and ball bearings. Toughened glass fibre reinforced Nylon frame and cheeks and U.V. stabilised, multi-strand impregnated SK75 Dyneema® link.
