Features
- Foot block cover plate can be removed for service access without removing the bolts that secure the block to the deck.
- Foot block base plate and hub section is machined in one piece from a single block alloy, for maximum integrity, with mounting bolts seated within the base plate and hub to minimise bending loads and prevent racking over of the block.
- Shape and edge radii of central hole in hub are compatible with fail-safe strops.
- Exceptionally high strength-to-weight ratio.
- Captive ball bearings for side thrust loads require no side retainer plates, reducing weight and providing a wider bearing surface for the Torlon needle rollers.
