RATCHET SHEAVES
HOLDING POWER
The patented extruded hole design, in conjunction with the groove profile of the sheave, provides a more powerful grip than conventional designs - up to 20:1 holding power. The anodised alloy sheave ensures maximum durability and strength-to-weight.
BALL BEARING ROPE SHEAVES
LOW FRICTION & HIGH PERFORMANCE
Acetal sheave with acetal ball bearings - efficient, lightweight all plastic sheave assemblies with ball bearings to take axial and thrust loads. Totally corrosion proof.
Alloy sheave with Torlon® ball bearings - oversize Torlon® ball bearings minimize friction and provide superior rolling performance. The narrow anodised alloy sheave is ideally suited to small diameter modern fibre control lines.
Alloy sheave with Torlon® rollers and acetal or Torlon® ball bearings - the ultimate high load, low friction sheave package. Torlon® needle rollers provide extremely high axial load performance and acetal ball bearings counter thrust loads. Available in self contained and 'hubless' models. Alloy sheave and components are hard anodised for corrosion resistance and durability.
ALL PURPOSE ROPE SHEAVES
ALL ROUND SOLUTION
Acetal - the fundamental moulded sheave material with excellent U.V. and dimensional stability combined with the proven self-lubricating properties of acetal.
Glass reinforced nylon sheave - the durability of nylon, reinforced with glass fibres for enhanced strength, mechanical strength and impact resistance
Acetal sheave with brass bearing for high load performance.
ALL PURPOSE - WIRE OR ROPE SHEAVES
STRENGTH & ABRASION RESISTANCE
Nylatron® – a partially cross-linked polyamide (nylon) compound, modified with MoS2 for lubrication to enhance free running and minimize line wear.
Aluminium sheave with brass bearing for high load performance.
Brass – durable marine grade brass, chrome plated for corrosion resistance and appearance. Dissimilar metal properties ensure free running on stainless steel shaft bolts.
