Radial Dampers

Radial dampers slow rotational movements and ensure continuous speed control over long distances.


Radial dampers limit the speed across the entire range of motion of a moving object, such as sliding gates or drives in mechanical engineering. They are particularly used in fire doors and fire gates, ensuring flawless and controlled opening and closing in emergency situations.


SCHNETZ offers a wide range of radial dampers, guaranteed to be manufactured with the highest quality and long service life:


  • The damping force can be precisely adjusted to specific requirements using an adjustment screw.
  • Our product range includes radial dampers for installation on chains, cables, timing belts, racks, and other special configurations.
  • The braking effect can be single-sided (single-sided braking with freewheel in the opposite direction) or double-sided.
  • We offer radial dampers with a holding mechanism – an electromagnetic element to keep the gate open.
  • We provide radial dampers with special oils for use in extreme temperatures and special housing materials.
  • Radial dampers can be customized to meet specific customer requirements.

Radial Dampers for chains

The radial damper for chains is specifically designed for the operation of chain-driven doors or gates. It regulates the movement of the gate through continuous speed control, even under high loads and over long distances. SCHNETZ offers radial dampers that ensure the safe and smooth closing of doors and gates (particularly sliding gates), especially in fire protection applications. These radial dampers minimize damage to the door and its surroundings while ensuring that the safety function operates reliably in critical situations.

Our radial dampers are specially approved for fire-resistant doors and gates, and the holding mechanism is DIBt-certified.

applications

Radial dampers cover a wide range of applications, from regular doors/gates and fire doors/gates to damping radial movements in various industrial applications. They can be used for doors/gates (particularly sliding gates and lift gates) driven by chain, cable, toothed belt, or rack-and-pinion systems. We can also manufacture custom radial dampers for other applications that match the specific requirements of your industrial system.


Typically, radial dampers are used primarily for specialized doors and sliding doors, especially in the field of fire protection. They ensure that doors open and close safely in emergency situations. The radial damper allows for precise control over the closing process and speed.
