Black Magic® AirBlocks®
Details Make the Difference
LOW-FRICTION CAGED BEARINGS
The center cage keeps Torlon® roller bearings separated and parallel
to reduce friction. Dirt and salt falls between rollers. Captive Delrin®
balls carry sideloads.
STRONG, LIGHTWEIGHT SIDEPLATES & SHEAVES
6061-T6 aluminum sideplates CNC sculpted to remove excess weight.
Thin-profile, deep-groove aluminum sheaves have radiused edges to
protect high-tech line.
LONG-LASTING PROTECTIVE FINISH
Sheaves and sideplates are deep-saturation Hardkote-anodized
for strength and durability, and UV-stabilized with black additive
for maximum protection. Teflon®-impregnated for a smooth,
slippery surface.
Strong, Lightweight
and Free Rolling
Weekend cruiser? Around-the-world racer? You’ll want Black
Magic® AirBlocks® aboard. With high strength-to-weight
ratios and free-rolling high-load roller bearings, these
versatile blocks are the workhorses of the Harken® line. Use
for sail controls that see lots of action including mainsheet,
runner, halyard, and spinnaker systems.
AirBlocks® are very easy to clean and service. They have few
parts and no loose balls or rollers to misplace. Unlike blocks
that are riveted together, three fasteners allow quick
disassembly for service.
75 mm
75 mm Black Magic® AirBlocks® feature Torlon® roller
bearings for strength and reduced wear. The unique
center cage separates rollers for less friction. Sideload ball
bearings are protected by sculpted aluminum sideplates.
Dissimilar metals are isolated to minimize corrosion.
Low-load blocks use Delrin® rollers and type 316 stainless
steel shackles.
Like all AirBlocks®, the three-way head swivels/locks in
front/side positions. Blocks are easily disassembled
with a single Allen wrench.
Use straphead blocks with LOUPS™ or straps aligned
fore/aft or side to side.
The 3196 soft attachment Loop block has a removable
dead end post for attachment to a padeye. Lashings can
also be used.
