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
