TULIP SERIES SHEAVES


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.

* The D=45 mm sheave is resin made with Delrin side ball bearings.

TURNING TULIP SHEAVES


This sheave is fitted with 4 wide Torlon ball bearings, this is the best solution when it is necessary to redirect the line to any angle.

VERTICAL TULIP BLOCKS


These vertical blocks are fitted with Tulip sheaves that accept very different lead angles.
This is a small and light solution that replaces traditional adjustable blocks.
More vertical blocks can be joined to form a set.

HORIZONTAL TULIP ORGANIZERS
With the “Tulip” it is possible to make also organizers with horizontal sheaves.
