Involute, Parallel & Serration

Plug type variable spline indicators are used to check effective & actual circular space width on an internal spline component. These spline indicators are typically supplied with digital Mitutoyo indicators which display a readout of the circular space width.

Functional Go and NoGo plug gauges are perfectly adequate for some manufacturers as they confirm if a component is within or outside the required tolerance band. However, for some manufacturers, it is necessary to actually measure and record the circular space width.

Spline Gauges specialises in the manufacturing of variable spline plug type indicators. We are able to offer a wide range of internationally recognised standards and use any bespoke designs to meet your gauging requirements. Some of the common standards include:
DIN
ANSI/AGMA
ISO
BS
JIS
SAE
NF E
NAS
RVZ

Spline Gauges also has the capability to produce straight or helical variable spline plug type indicators to suit customer requirements.
