Introduction to the friction brake
This article covers Friction brakes, from the basic principles of this braking technology to advanced industrial applications. Criteria for selecting suitable braking solutions, especially in the area of friction brake, for efficiency and safety in the drive train will be explained. The aim is to deepen knowledge about friction brakes and contribute to system optimization.
Understanding the core principle
Friction brakes converts motion energy into heat through precisely controlled friction to manage heavy loads. This principle of the friction brake is critical for industrial processes, such as stopping production lines with ±0.5 mm accuracy.
More than just stopping
Modern Friction brakes not only serve to stop but also to control the holding of positions (e.g. robot arms in assembly technology) or defined deceleration, for reducing vibrations in textile machines by up to 40%. Such braking systems are therefore versatile.
The invisible heroes of everyday life
High-quality Friction brakes, such as systems from ATEK Drive Solutions, ensure safety and productivity in facilities with continuous operation, for example in elevators, even when this type of brake rarely comes into focus.Functioning and types of Friction brakes
The braking principle of a friction brake is based on converting kinetic energy into heat through friction forces that arise upon contact between two surfaces. Modern brake technology for such friction brakes uses this purposefully; material combinations such as sintered metal linings on steel discs achieve friction coefficients of up to 0.5 µ.
- The core principle of every friction brake is the conversion of kinetic energy into heat through friction.
- Modern brake technology for Friction brakes relies on specific material combinations, such as sintered metal linings on steel discs, which achieve friction coefficients of up to 0.5 µ.
- Industrial disc brakes, a common form of friction brake, are characterized by good heat dissipation and are suitable for fast cycles in machine tools.
- Encapsulated drum brakes, another type of friction brake, offer robustness and are ideal for dusty environments, such as in cement plants.

In contrast to standardization in the automotive sector, industrial applications – from packaging machines (120 strokes/min) to cranes – often require custom-made industrial brakes, which are often designed as Friction brakes for specific load profiles and environments.
Precision in machine and plant engineering
High-precision Friction brakes, often integrated into servomotors, enable precise positioning (e.g. to 0.02 mm) and holding of components by robot arms. This holding accuracy through special friction brakes is essential for automated manufacturing processes (e.g. electronics manufacturing). ATEK develops such integrated braking solutions.
