Description
Ronstan's ball bearing blocks were conceived and engineered for the demands of competitive sailing in all types of boats and have rapidly become the international choice for high performance hardware.
- Highly efficient, low friction bearing systems for optimum sheeting and trimming performance
- Precision molded Acetal sheaves running on stainless steel or Torlon ball bearings provide high performance & low friction and provides a unique 2-Stage bearing system:
- Stage 1: Under moderate loads, Acetal ball bearings ensure minimum friction
- Stage 2: Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished Stainless steel race takes over, maintaining low friction performance
