Harken Megayacht Blocks

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
