MIKI PULLEY

The Electromagnetic Clutch and Brake Unit 121(20G) is an open-structure clutch and brake unit with a through-shaft design, featuring a lightweight alloy drum with a clutch and brake mounted on the outside. Power input is handled through the input hub, and continuous output is provided through the output shaft. By energizing the brake when the clutch current is cut off, the output shaft can be braked. The structure, with its wide bearing span, is robust against radial loads and allows for the attachment of V-pulleys and spur gears. This unit is adaptable for various applications and capable of high-tension use.

Features

High-Performance Double Clutch Structure: Clutches are arranged on both sides of the drum, supporting two-speed changes and forward/reverse operations.
High Durability Design: The wide bearing span allows usage under high tension.
Space-Saving Design: Compact through-shaft structure for easy installation.
Versatile Applications: Ideal for printing machines, bookbinding machines, woodworking machines, and semiconductor manufacturing equipment.
Easy Installation: The wide bearing span structure allows for easy attachment of V-pulleys and spur gears.
