RONSTAN Blocks - Ball Bearing Size 20 - Overview


Trim for Speed - Ronstan's Series 20 Ball Bearing and High Load blocks, conceived and engineered for the demands of competitive sailing in skiff, Olympic and sports boats classes, have rapidly become the international choice for high performance hardware.
Use on boats of all sizes for sheets, fine tune and control line applications.
Highly efficient, low friction bearing systems for optimum sheeting and trimming performance.
Comprehensive range of sizes and configurations offers solutions for powerful multiple purchase and cascade systems.
Practical features designed into the blocks provide extra versatility.

Ball Bearing Blocks - meet the high performance demands of running sheet applications with a unique two-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. Regular flushing with fresh water to remove salt and sand will maintain optimum performance over a long service life. These blocks are an excellent choice for main and jib sheets, spinnaker sheets and control lines.
