Cylinder For Air Ratchet Wrench

At a Glance: Replacement motor cylinder for the AirCraft AT0016 air ratchet—provides the smooth bore and sealing surface that the vanes run against.

The cylinder is the “track” your rotor blades ride on—and the sealing surface that lets compressed air do real work instead of sneaking past internally. The AirCraft AT0016-15 Cylinder is a replacement motor cylinder for the AirCraft Air Ratchet Wrench (AT0016 series). If the original cylinder is scored, worn, or damaged, the vanes can’t seal properly, which means less torque, more air consumption and rougher running. Replacing the cylinder during a rebuild restores the correct internal bore and porting surfaces so your air ratchet runs smoother, hits harder and stays reliable in daily workshop use.

In a vane motor, the cylinder’s internal surface quality matters a lot. A smooth, true cylinder helps the rotor blades seal cleanly, reduces friction, and improves overall motor efficiency—especially when paired with clean air and correct lubrication.
