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