Linear Scales

Quick Answer

A linear scale is a position-measuring device that converts the linear displacement of a machine axis into an electronic signal — providing accurate, real-time position feedback for CNC machine tools, manual mills, lathes, grinders, and metrology equipment. Linear scales are the sensing component that feeds position data to a digital readout (DRO) or CNC controller.

Higher Precision stocks linear scales from Mitutoyo, ACU-RITE, Heidenhain, INSIZE, and SPI — optical, magnetic, and glass linear encoders for DRO retrofits, CNC machine tools, CMMs, and custom metrology applications. Need help selecting? Call us at 800-469-0132 or contact us online.
