ACETAL SHEAVES
Choice of bearings
Acetal ball bearings - minimum friction under
moderate loads.
Solid bearing - high strength and durability,
utilizing the self-lubricating proper ties of Acetal.
Oilite
®
bearing - Oil impregnated self-lubricating
bearing for highest load applications.
U.V. resistant Acetal sheaves.
GLASS REINFORCED NYLON SHEAVES
Glass reinforced for greater strength and
abrasion resistance.
NYLATRON
®
SHEAVES
Cast par tially cross-linked polyamide compound,
modified with a MoS2 filler for lubrication and to
minimize wear.
Suitable for use with wire or rope.
ALUMINIUM SHEAVES
Suitable for use with wire or rope (excludes ratchet).
Self-lubricating Oilite
®
bearing.
Anodised aluminium for corrosion resistance
and high strength.
BRASS SHEAVES
Suitable for use with wire or rope.
Nickel plated for corrosion wear resistance.
