The entire line of Black
Magic® AirBlocks® has been redesigned with a sleek new look. Their
unique, performance-packed engineering remains exactly the same.
These strong, lightweight
blocks feature free-rolling, high-load Torlon® roller bearings
for a high strength-to-weight ratio. Use them for sail controls that
see lots of action: mainsheet, runner, halyard, and spinnaker systems.
AirBlocks® are easy to
clean and service. They have few parts and no loose balls or rollers
to misplace. Unlike blocks that are riveted, fasteners allow quick
disassembly with a single hex wrench.
Low Friction Caged
The center cage keeps Torlon® roller bearings separated and parallel
to reduce friction. Dirt and salt falls between rollers. Captive
Delrin® balls carry sideloads.
Sideplates and Sheaves
6061-T6 aluminum sideplates are CNC-sculpted to remove excess weight.
Thin-profile, deep-groove aluminum sheaves have radiused edges to
protect high-tech line.
Sheaves and sideplates are deep-saturation Hard Lube-anodized for
strength and durability. UV-stabilized and PTFE-impregnated for
maximum protection and a smooth, slippery surface.
