Center cage keeps Torlon® roller bearings separated and parallel to reduce friction. Captive Delrin® ball bearings carry side loads.
Harken Black Magic Air Runners
Runners are used on running backstays of offshore boats to adjust mast bend for different wind conditions. Integrated sideplate bails and recessed cotter key help produce a smooth design that won’t snag lifelines. Foam padded Block Socks easily install over Air Runner blocks to protect your blocks, deck, and crew.
