Rotalock Mandrels (Arbors)

Involute, Parallel & Serration

Spline rotalock arbors or mandrels have a rotating section of teeth for clamping on internal spline components and are used for machining and inspection purposes.

We also design and manufacture expanding key type arbors and expanding collets. Expanding key type arbors are generally used for clamping on major diameter fitting splines for machining or grinding purposes. Expanding spline collets utilise a split collet with a spline on the outside mounted on a ground tapered diameter mandrel.

Spline Gauges specialises in the manufacturing of rotalock arbors, expanding key type arbors and expanding spline collets to suit customer requirements.
