RONSTAN Blocks - Core Blocks Size
75 - Overview |
Ronstan Core Blocks™ Series 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.
Ronstan Ball Bearing Orbit Blocks™ Series boast
the highest strength-to-weight ratio available. Less friction
provides you with ultimate performance. This is achieved through
all-composite reinforced polymer materials
and a Dyneema® rope link head. Their precision design allows
the optimum number of ball bearings in loaded areas and eliminates
them in inactive areas. Ineffective mass is reduced even further
through fibre-reinforced composites in the block head, cleat
arms and beckets. The incredible Series 20 Orbit Block is capable
of loads up to 250kg (550lb) while weighing a mere 9 grams. It's
so light that it needs to be lashed down!
Ronstan Series All purpose (AP) blocks are
a great all around solution. Self-lubricating Acetal polymer
sheaves running
on polished
stainless steel
races perform equally well with dynamic loads and high static
loads.
For durability and a long service life, these blocks are
the right choice for sheets, halyards and control line applications
for cruising and racing.
Ronstan Utility Blocks feature stainless steel cheeks and Acetal
sheaves ensure a long service life with virtually no maintenance.
Hollow rivets in the
block heads can be fitted with shackles, which can also be
used to
add a becket for extra purchase.
