Clutches and brakes are essential mechanical components that control power transmission and stopping in machinery. They include electromagnetic clutches, friction clutches, one-way clutches, electromagnetic brakes, disc brakes, and drum brakes. These components are indispensable for precise motion control in manufacturing lines, including spindle control in machine tools, safety stopping in press machines, positioning in conveyor systems, and tension control in winding equipment. They provide functions such as torque transmission engagement/disengagement, braking/holding of rotating bodies, and reverse rotation prevention, contributing to operator safety and product quality improvement. Available in electric, hydraulic, and pneumatic drive types, optimal product selection based on response speed, braking torque, and durability specifications is crucial.
