Rotor Minor Diameter Micrometer (MM) Gagemaker’s minor diameter MIC gage was designed to measure a rotor’s minor diameter. The spiral lobes on the rotor produce a valley, or minor diameter. The depth of the minor diameter from the major diameter requires a 1” travel indicator stem. Gage range is 0” - 6”, which allows measuring most rotor sizes with only one gage. Ensuring the gage’s durability and long life, Gagemaker’s design uses a heavy duty indicator stem and bearing housing to withstand side loads. Special sizes are available.

Core Alignment Gage Verification that the core was properly placed when the stator was molded is easily checked using the Core Alignment Gage. The gage is supplied with brass alignment inserts that match the thread of the injection ports. The digital gage plunges a needle through the rubber to contact the core. Measurements are made at 180° locations to verify that the core is indeed centrally located to the OD of the stator.

Rotor Saddle Gage The rotor saddle gage, also known as a rotor lobe height gage, is the last weapon in the inspection arsenal. This gage sets on top of the spiral lobes of the rotor and measures the variation in lobe height. Sliding the gage along the length of the rotor detects variation in root to crest height of all the lobes. Measurements can be taken at 90° or 180° intervals to provide an accurate dimensional map of the relationship between lobes. This inspection aids in manufacturing the rotor to specification.
