RONSTAN Blocks - Core Blocks Size
75 - Overview |
Ronstan Core Blocks™ Series 75 are a true
all round solution. A tuned 2-stage bearing system provides excellent
performance
across the full
working load range with an integrated thrust bearing feature
and the resilience
to handle high dynamic or static loads. Acetal sheave, alloy
cheeks and stainless fixings complete the durable package. For
reliability and a long service life, these blocks are the right
choice for
sheets,
halyards and control line applications for cruising and racing.
Universal Bearing -
Dynamic and high static load performance
The Ronstan Universal Bearing incorporates our proven 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.
Additionally the ball bearings are configured to act as a thrust
bearing between the sheave and cheeks, preventing the sheave
from rubbing on the cheeks and causing friction when the line
lead in and out of the block isn’t perfect. Particularly
important for cheek blocks.
Alloy cheek plates.
Block cheeks are manufactured from the highest quality alloy
for maximum strength. Material optimisation and the cut-away
design minimises weight and allows easy fresh water rinsing of
salt and debris from the bearings. Cheek design has been further
styled with flaring at the block throat and reduced gap between
the cheek and sheave, minimising rope wear.
