Due to high spirals on the lobes, conventional measurement gages cannot be used for measuring rotor major diameters. Gagemaker developed the T-MIC to measure a rotor’s major diameter. The T-MIC’s base spans across two lobes on one side of the centerline and uses a micrometer thimble on the other to measure the diameter. Instead of modifying an existing micrometer, Gagemaker custom builds each T-MIC. Each T-Mic is made to fit a 1″ range of rotor diameters.Gagemaker’s rugged design far exceeds all others on the market today.
Special sizes, metric thimbles, and metric sizes are available; contact customer service for more information.
