Learn how shaft-mounted holding brakes protect your systems and enhance performance – including application examples and selection criteria.
What is the main function of a holding brake for a shaft?
A holding brake for a shaft primarily serves to secure loads safely and prevents unwanted movements, especially in the event of a power failure or when at rest. It is crucial for plant safety and precise positioning.
How does a spring-operated shaft holding brake work?
Spring-operated holding brakes utilize built-in spring packages, to mechanically generate braking force in a power-off state (Fail-Safe principle). The brake is electromagnetically released, as soon as power is applied, allowing for controlled release. ATEK’s WFG series is an example of this.
What criteria are crucial when selecting a shaft holding brake?
Important selection criteria include the required static holding torque (e.g., ATEK WFG series 0.12-1,500 Nm, BCD series 0.4-5.0 Nm), the available installation space, the reaction time, the switching frequency (on-time) and the environmental conditions (e.g., requirement for IP65 protection).
Can a holding brake be used for dynamic braking operations?
No, holding brakes are designed for static holding and not for decelerating movements (dynamic braking). Using them for dynamic braking leads to increased wear and can drastically reduce the service life of the brake. ATEK is pleased to advise you on selecting the appropriate operational brake.
For which applications are ATEK’s shaft holding brakes particularly suitable?
ATEK’s shaft holding brakes are ideal for vertical axes in machine tools, conveyor systems, robotics applications, elevator technology and in the medical technology – everywhere reliable and safe positioning of loads at rest is required. von Lasten im Stillstand gefordert ist.
What advantages does the ATEK WFG series offer as a holding brake for shafts?
The WFG series is characterized by a very compact, space-saving design , offers quick reaction times and a wide torque range from 0.12 Nm to 1,500 Nm. Optional features such as a manual release device further increase application flexibility.
What differentiates a holding brake from an operational brake?
A A holding brake (parking brake) is designed to securely hold a load or machine component in position when at rest, often as a safety feature in the event of a power failure. An operational brake on the other hand is constructed to actively decelerate a moving mass and convert kinetic energy.
Why is the correct sizing of the torque in a shaft holding brake so important?
The correct dimensioning of the holding torque is essential for safety and functionality. If the torque is too low, the load cannot be held reliably, leading to dangerous situations or damage. Oversizing is uneconomical. ATEK supports the precise sizing.
Choosing the correct holding brake for the shaft is crucial for operational safety and system lifespan; improper use for dynamic stops can increase maintenance costs by up to 30% and lead to system failures .
Spring-operated brakes such as ATEK’s WFG series (0.12-1,500 Nm) provide reliable fail-safe holding and precise control, which is essential for robotics and vertical axes and can increase system availability by up to 20%. Systemverfügbarkeit um bis zu 20 % steigern kann.

Understanding shaft holding brakes and using them optimally.
Selecting the right holding brake for the shaft is essential for system protection and performance optimization. This article explains important criteria and application examples to achieve maximum reliability and efficiency.
Such holding brakes for shafts serve to secure loads and prevent unwanted movements, especially in case of power failure, for example on vertical axes. The reaction time, an often underestimated factor, strongly depends on the control of the respective shaft holding brake – ATEK offers optimized solutions up to 1,500 Nm. Positioning brakes for shafts fundamentally differ from operational brakes: While operational brakes execute dynamic stopping operations, holding brakes maintain positions statically.
Careful selection of a safety brake is crucial. Incorrect use of a holding brake for dynamic braking operations results in rapid wear. ATEK Drive Solutions supports you in selecting the technically appropriate braking solution, whether as a holding brake for a shaft or as a dynamic industrial brake, to avoid system failures.Learn about the functionalities and designs of holding brakes.
Spring-operated brakes for shafts, such as ATEK’s WFG series (0.12-1,500 Nm), mechanically close during power failure according to the fail-safe principle. A properly sized brake of this type can hold a load of 100 kg safely. Although ‘fail-safe’ suggests high basic safety, the correct torque sizing is decisive for actual safety. Electromagnetically released, these brakes allow for precise control in every shaft brake system..
- Spring-operated brakes, like the ATEK WFG series, utilize the fail-safe principle and mechanically close during power failure.

Shaft holding brakes are used in a variety of applications, from robots to conveyor systems securing goods up to 2 tons. The assumption that a standard brake is universally applicable can lead to performance compromises; custom modifications are therefore often crucial. Important selection criteria include holding torque (e.g., BCD series: 0.4-5.0 Nm), permissible speed, protection class (e.g., IP65), and switching duration. A careful analysis of requirements is fundamental for selecting the appropriate braking technology for the specific holding brake of a shaft is essential.

Progress in automation and the use of cobots increasingly require compact brake solutions, such as the ROBA®-servostop® from Mayr, which weigh less than 500g in some cases. An aspect of growing importance is the electromagnetic compatibility (EMC) of the brake, especially in connected systems. In the future, intelligent brakes with integrated condition monitoring will gain relevance to optimize system availability. ATEK is following current trends, also in the field of electric motors with brakes.
Safety aspects require special attention in vertical axes, where certified safety brakes for the shaft are required (e.g., KSP series, in accordance with EN ISO 13849-1). The complexity of integrating safety brakes into controls to achieve performance levels such as PL d is sometimes underestimated. Regular maintenance is essential for long-term functional reliability. ATEK provides expertise and supports with digital infrastructure for safe brakes.
