Learn all about the operation, the various areas of application, and the advantages of floating caliper brakes in industrial applications.
What is a floating caliper brake and why is it relevant in industrial applications?
A floating caliper brake is a disc brake design with an axially movable brake caliper and pistons on only one side. It is relevant for industrial applications due to its robust construction, adaptability and the ability to deliver high braking forces as required in heavy industry.
What are the main advantages of floating caliper brakes for industrial machines?
Industrial floating caliper brakes often offer an axial freedom from force, which protects the drive train. Additional advantages include their modular design for easy adaptation, compact dimensions and a high reliability. Models like the KTR XS series are even designed for extreme temperatures down to -40°C .
How does the fist caliper brake differ from other floating caliper brakes?
Die Fist caliper brake is a common design of the floating caliper brake, where the caliper is usually a single piece and the guide pins are directly integrated. It is considered particularly reliable and cost-effective due to a reduced number of components compared to older floating frame constructions.
Are floating caliper brakes suitable for safety-critical applications like emergency stop functions?
Yes, particularly spring-actuated (passive) floating caliper brakes are ideal for emergency stop and holding functions, as they brake safely in a power-off state (Fail-Safe). Electromechanical variants (EMB) such as the EMB-STOP series also offer very fast response times for safety applications.
What maintenance do industrial floating caliper brakes typically require?
Maintenance includes the regular inspection of pad thickness and the condition of the brake disc. It is crucial to ensure the testing and lubrication of the guide pins, to ensure their free movement and prevent uneven wear. The open design of many models facilitates pad replacement.
Can floating caliper brakes be adapted for specific industrial environments, e.g., extreme cold?
Yes, many manufacturers like ATEK Drive Solutions offer custom adaptations. For example, floating caliper brakes like the KTR XS series are made of LT spheroidal cast iron and validated for use at temperatures down to -40°C , making them ideal for onshore/offshore or mining applications.
What does “axial freedom from force” mean in floating caliper brakes and why is it important?
Axial freedom from force means that the brake exerts no or only minimal lateral forces on the brake disc and thus on the shaft or the Gear Boxes. This is crucial to avoid damage to the drive train, especially with slight misalignments or thermal expansion.
How do electromechanical floating caliper brakes (EMB) compare to hydraulic ones for industrial use?
EMBs often offer faster response times and more precise control than hydraulic systems. They are advantageous when no hydraulic unit is desired or a simple electrical integration is preferred. Hydraulic systems, on the other hand, can often achieve higher braking forces with compact construction.
Floating caliper brakes are a versatile and reliable braking solution for numerous industrial applications, from standard machines to demanding environments such as offshore or mining..
Key design advantages such as the axial freedom from force protect the drive train, while modular systems and special materials allow operation in temperature ranges of -40°C to +50°C and for braking forces up to 370 kN .
The right selection, for example between hydraulic, electromechanical, or spring-actuated variants, as well as regular maintenance of the guide pins are crucial for optimal performance and a long service life of the floating caliper brake.Discover the world of floating caliper brakes: from the basics to the technical details and the various applications in modern drive technology.

Understanding the basics of floating caliper brakes
Floating caliper brakes optimizes industrial drive solutions. This article explains the function, advantages, and applications of these proven caliper brakes to support brake selection.
What exactly is a floating caliper brake?
Die floating caliper brake (also known as Fist caliper brake ) is a disc brake design with an axially movable brake caliper and single-sided pistons. This design of the floating caliper brake is compact, cost-effective, and proven in automotive engineering.
How does it differ from other types of brakes?
Unlike fixed caliper brakes with double-sided pistons, in the case of the floating caliper brake the piston presses the inner pad against the disc. The reaction force shifts the caliper and ensures even pressure of the outer pad. Die Fist caliper brake is a typical example of this and is often regarded as more reliable compared to older floating frame brakes. Fixed caliper brakes explained as a comparison.
The development: From floating frame to fist caliper brakes
Starting from the 1980s, the Fist caliper brake rose to prominence due to reduced guide elements, which increased the reliability and cost-effectiveness of these braking systems. The more complex floating frame brake has thus been increasingly supplanted. More about floating caliper brakes and their evolution.Analyzing the function and structure of the floating caliper brake precisely
The hydraulic principle of operation demystified
In a floating caliper brake , hydraulic pressure acts on the piston, which presses the inner pad against the disc. The floating caliper bearing generates a reaction force, which draws the caliper and thus the outer pad. Industrial models of such caliper brakes can achieve, for example, 370 kN of braking force.
- Hydraulic pressure activates the piston, which presses the inner brake pad against the disc.
- The floating mounting of the caliper generates a reaction force that presses the outer pad – a core feature of the floating caliper brake.
- Among the main components of a floating caliper brake are brake caliper, piston, brake pads, brake disc, and guide pins.
- Guide pins are crucial for the axial mobility of the caliper in this brake type..
- A certain amount of caliper clearance is necessary for the correct functioning of the floating caliper brake .
- The free movement of the guide pins ensures that the pads of the Fist caliper brake release and do not drag.
