Precision Gage provides a full range of Effective/Functional Spline Ring and Plug gages to meet your specifications. Go and No-Go gages are available in composite or sector forms (Involute, Straight-sided, Parallel. Helical. Alignment/Concentricity) and certifiable to NIST. Taper Master Plugs are available for use with composite Go or sector No-Go ring gages.

Indicating Spline Gages offer accurate measurement of effective/actual tooth or space thickness within .0001 by comparison to a set master. Rotating center section measures size variations while transferring its motion to an indicator for digital/dial readout. Available with outputs for SPC. Our Combo Spline Checker can precisely check tooth/space thickness and also check taper, hollow, crown and out-of-round. Internal or external models available.

Measurement over balls or between balls indicating spline gages are also available.
