Master Gears USA

We are one of the leading manufacturers and suppliers of top-quality master gears in the USA. External and internal Master Gears are used for the composite checking of components.

This is generally achieved by putting the master and component gears in hard mesh on a machine that records the deviation of centre distance during the rotation of the gears.

High Quality External Master Gears

External master gears may also be used for evaluating a gear system for noise, vibration and harshness (NVH), known as single flank roll testing.

As a USA master gear manufacturer and supplier, Spline specialises in manufacturing both internal and external master gears and we pride ourselves on our supreme quality.

We are also able to offer master gears in a wide range of internationally recognised standards to meet any customer requirements in the USA and internationally.
