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.
Applications:
Dinghy control lines
Dinghy vangs
