Megayacht Blocks<br />
New<br />
Megayacht blocks are designed to handle the extremely<br />
high loads generated by today’s large ocean-going<br />
monohulls and multihulls. The Teflon ® -impregnated<br />
ultra-light composite bearing system (ULC) rides on a<br />
heat-treated 17-4 PH stainless steel inner race to handle<br />
primary loads. Snap-fit Torlon ® ball bearings carry thrust<br />
loads. Megayacht blocks are available in Hardkoteanodized<br />
6061-T6 aluminum and mirror-polished<br />
stainless steel.<br />
ULC bearing construction allows a<br />
narrower sheave to reduce weight<br />
Use hollow inner race as a<br />
becket attachment for<br />
weight reduction<br />
