Any Ball Lock application requires at least two sets of shanks, receiver bushings and liners. The liners
are placed into the fixture plate to ensure extremely accurate positioning. If more than two shanks are required (to provide additional hold down force), omit the liner bushing so
that these additional holes will not interfere with the primary locating holes.

Locating repeatability will determine if one primary and one secondary or two primary liners are needed.
With two primary liners, repeatability of ±0.013 mm can be maintained if the two holes for receiver bushings
are held to a centerline distance of ±0.005 mm tolerance.
Bolt-In Recessed Bushing
Two styles of receiver bushings are available. Generally, the Bolt-in Recessed Bushing is
utilized in blind hole applications (slip fit). The Reverse Mount bushing is used in through hole applications (light press fit).
