125 Models (Clutches and brakes)

ダウンロード

Features of 125 Models (Clutches and brakes)

These are anti-drip clutches and brakes that have split-shaft constructions of clutch and brake within a light alloy housing.Power is output from the input shaft continuously to the output shaft. The output shaft is braked when clutch current is shut off and the brake is energized in response. These models come with either steel plate or cast (E type) mounting bases. Mounting is simple, and service life is long.
