Precision moulded Acetal ball bearing sheaves running on Acetal or Torlon® ball
bearings provide high performance & low friction. These U.V. resistant
acetal sheaves operate with Minimum friction under moderate loads
These Ronstan Acetal oilite bearing sheaves feature
self lubricating Oilite Bronze bearings for greater load capacity and
high strength Bronze, which ensures that the surface is always lubricated.
These Ronstan Nylatron sheaves are made from a unique
plastic material which is suitable for use with wire. Nylatron® is
a cast, partially cross-linked polyamide compound which has been modified
a MoS2 filler. It has excellent wear resistance, self lubrication and
low friction properties.
These Ronstan Nylon sheaves are made with glass reinforcement
for greater strength and abrasion resistance. These sheaves are used
for high load applications.
Ronstan's range of Acetal sheaves is moulded from a specially modified
ultra-violet resistant grade of material to provide a long service
life in the tough marine environment. Acetal is well suited to the
application, with characteristics of high strength and resistance to
impact and wear. It also exhibits excellent low friction properties
for bearing applications. These Roller Ball Bearing Sheaves
from Ronstan are manufactured to operate with low friction under load.
Ronstan manufactures an extensive range of sheave boxes for use with
rope and wire. Plain bearing sheaves are ideal for halyards and other
applications where high static loads are likely to be encountered. The
Ronstan Sheave Boxes use Nylatron Sheave within a grade 316 stainless
