45mm Tulip series 12mm sheave

The Tulip sheaves are fixed sheaves that do not turn in the direction of manoeuvres since they accept quite different lead angles. The choice of a Tulip sheave instead of a revolving block comes from the need to reduce bulk and weight. The sheave, with an axial bearing in composite fibre and large round bearings (self-captive) in Torlon for side loads, is in anodized and Teflon coated aluminium and can handle very high loads.
