GUMMI FKE Pneumatic Elements for Low-Speed Applications

Smooth Starting and Stopping with Expanding Friction Design
The GUMMI FKE pneumatic elements are designed for low-speed applications, providing smooth starting and stopping loads. Their unique expanding friction design allows them to function as both clutches and tension brakes. By pressurizing the air tube, the friction shoes expand and engage with the drum's inner diameter to transmit torque. These elements are highly durable and efficient, suited for a wide range of industrial applications. The FKE series is available in 11 different sizes, identified by the inner diameter of the drum and the width of the friction linings. Torque transmission depends on applied air pressure and operating speed.

Product Description:
The GUMMI FKE pneumatic elements are designed for low-speed applications, providing smooth starting and stopping loads. These elements function as slip clutches and tensioning brakes, similar in design to the FK elements. Their unique expanding friction design enables them to operate as centrifugal clutches. Made with a reinforced neoprene rubber tube vulcanized to the outer part of a steel rim, the FKE elements deliver efficient torque transmission. When pressurized, the friction shoes expand, engaging the inside diameter of the drum for smooth operation.

Smaller FKE models feature a solid hub, allowing direct shaft mounting, while larger sizes are attached to the shaft via a separate element hub. The FKE series ensures reliable performance in demanding industrial environments, including applications like tension control, braking, and speed regulation.

Key Features:

  • Ideal for low-speed applications, smooth start/stop loads, and cyclic operations.
  • Expanding friction shoe design with centrifugal clutch functionality.
  • Neoprene tube reinforced with cord plys for enhanced durability and performance.
  • Torque transmission depends on applied air pressure and speed.
  • Available in 11 sizes, identified by the drum’s inner diameter and friction lining width.
  • Smallest size works on a 4-inch drum, and the largest on a 24-inch drum.
