Design and Function of Brakes

No Drives without Disc Brakes

For a long time now Disc Brakes have been tried and tested in the aviation and ­auto­motive ­industry, and increasing awareness of operational safety and ever stricter rules on accident ­prevention have made them ­indispensable.


After all, wherever there is acceleration, there must also be braking. A ­reliable and economic solution to these ­problems are RINGSPANN Disc Brakes.

Advantages of RINGSPANN Disc Brakes

The following features make the RINGSPANN Disc Brakes unique:

  • The well thought-out design of RINGSPANN Disc Brakes permits a simple and space-­saving arrangement, even in existing installations.
  • Due to the even friction surfaces the ­RINGSPANN Disc Brakes are not subject to any automatic amplification effect which is always a problem with drum brakes. Therefore, disc brakes guarantee high torque stability even when friction variations occur.
  • The open design of the RINGSPANN Disc ­Brakes with their excellent ventilation characteristics provides ideal heat ­dissipation; this is a precondition for high braking power with a compact design.
  • The considerably lower inertia moment compared with that of drum brakes ­permits economical dimensioning, ­shortened cycle times and reduced energy consumption.
  • Highly wear-resistant friction material and large braking surfaces ensure long intervals between maintenance. The ­practical and ­robust design of ­RINGSPANN Disc Brakes makes that maintenance easy and un­complicated. The friction pads are easily ­re­placed without the need to remove the brake.
  • RINGSPANN Disc Brakes are fitted with swivel mounted friction blocks; this ­ensures that the friction blocks are ­always in full face ­contact with the brake disc. When the brake is released, the ­friction blocks are lifted safely off the disc by a spring, irrespective of the ­installation arrangement.

For each Application the right Solution

RINGSPANN Disc Brakes require minimal ­installation space. Brake Calipers or Brake Saddles may be arranged in any position on brake discs of varying diameters. By using ­several Brake Calipers on the same disc it is ­possible to increase the braking torque ­without the need to enlarge the installation ­space.


The universal concept of the RINGSPANN Disc Brake fulfills various functions:

  • Stopping brake
  • Control brake
  • Holding brake

As a stopping brake, it brings a rotating shaft to a standstill in a short time, for ­example ­during a power failure or an ­emergency stop.

As a control brake, it effectively maintains ­material tension.

As a holding brake, it prevents the ­un­intended start of a stationary shaft.

The Product Range

RINGSPANN offers a comprehensive range of Disc Brakes:

  • Spring activated Brake Calipers; release is either pneumatic, hydraulic, ­electro­mag­netic or manual by means of a pull cable.
  • Pneumatically activated Brake Calipers; spring released
  • Manually activated Brake Calipers; manually released with a hand wheel or a pull cable
  • Hydraulically activated Brake Calipers; spring released
  • Spring activated Clamping Unit; hydraulically or pneumatically released


Accessories are available for ­special applications:

  • Two standard types of brake discs are ­available with diameters ranging from 125 mm up to 1 000 mm
  • All brakes can be supplied with an ­electric ­indicator for friction block wear
  • Inductive proximity switches for moni­toring the operating condition “brake ­released“ are ­available

  • To prolong the operating life, friction blocks with double the friction surface are ­available for Brake Calipers sizes 12, 15, 20 and 30
  • Special friction linings are available for special requirements
