100mm Black Magic AirBlocks feature Torlon roller bearings for strength and reduced wear. The unique centre cage separates rollers for less friction. Sideload ball bearings are protected by sculpted aluminium sideplates. Dissimilar metals are isolated to minimise corrosion.

Low-load blocks use Delrin rollers and 316 type stainless steel shackles. Like all airBlocks, the three way head swivels and locks in front and side positions. Blocks are easily dissassembled with a single allen wrench.
