Safety, performance and longevity: How to choose the right mineral oil for your industrial brake applications.
Why is the right mineral oil selection so important for industrial hydraulic brakes?
The correct selection of mineral oil for hydraulic brakes is crucial for the safety, performance, and lifespan of your machines. Wrong oil can lead to premature wear, system failures, and costly production stoppages for example, by reducing the holding force by up to 15%.
What are the main differences between mineral oil and DOT brake fluids in industrial use?
Mineral oils are not hygroscopic (do not absorb water), which increases their long-term stability and minimizes corrosion. DOT fluids are hygroscopic, leading to a decreasing boiling point and corrosion risk . For industrial applications with high demands on lifespan and material compatibility (e.g. with NBR/FKM seals), mineral oils are often superior..
What key parameters should I consider when selecting mineral oil for hydraulic brakes?
Important parameters are a high viscosity index (VI > 150) for constant response behavior, a high dry boiling point (ideally >220°C) und wet boiling point (>160°C) to prevent vapor bubble formation, as well as a specific additive package to protect against wear, corrosion, and oxidation. The manufacturer specifications are always binding..
Can I mix mineral oils from different manufacturers or replace them with alternatives?
Mixing different mineral oils, even with similar specifications, is not recommended, as additive packages may be incompatible. Mixing with DOT fluids is strictly to be avoided, as this can lead to seal damage. The use of non-approved alternatives is done at your own risk and may affect the warranty..
How often should mineral oil be changed in industrial hydraulic brakes?
The change intervals depend on the operating conditions and the results of regular oil analyses . As a guideline, a change is often recommended every 3-5 years or after 10,000-20,000 operating hours to remove wear particles and aged additives. An oil analysis should be carried out, for example, every 2,000 operating hours or annually.
What are the consequences of using unsuitable mineral oil?
Using unsuitable oil can lead to increased wear, seal damage (e.g. swelling of EPDM seals by up to 25%), corrosion, reduced braking performance, and system failures . This can lead to significant production losses and repair costs .
Why are manufacturer specifications so crucial when selecting mineral oil?
Manufacturers such as ATEK specify oils that are optimally matched to the materials and performance requirements of their brake systems. Adhering to these specifications ensures the functionality, safety, efficiency, and lifespan of the brakes (e.g. over 20,000 operating hours) and is often a prerequisite for warranty claims..

Laying the foundations: Understanding mineral oil in industrial hydraulic brakes.
The role of mineral oil in high-performance brakes
The correct selection of mineral oil for hydraulic brakes is critical for heavy machinery. Mineral oil transmits braking force, lubricates, and cools – essential for emergency braking (e.g. wind turbine, 500 kW). A careful design of the hydraulic brake is fundamental, as underestimating the requirements for the operating fluid leads to wear.
Mineral oil versus DOT fluids in the industrial context.
In the industrial context, DOT fluids are often less suitable due to their hygroscopic properties (corrosion, decreasing boiling point). In contrast, mineral oils offer higher long-term stability and better material compatibility, especially with NBR/FKM seals.. Quality mineral oils can maintain their boiling points above 180°C even after five years. This is an important aspect of the selection of mineral oil for hydraulic brakes and equally relevant for hydraulic systems..
The challenge: Lack of standardization in mineral oils.
The challenge with the selection of mineral oil for hydraulic brakes is that not every ‘hydraulic’ mineral oil fits. Unlike DOT fluids, there are often no overarching standards here; viscosity and additive packages can vary widely.Manufacturers such as ATEK therefore specify approved oils for their systems (e.g. spring-loaded hydraulic disc brakes), to ensure a lifespan of over 20,000 operating hours.Defining performance: Identifying critical criteria for mineral oil selection for hydraulic brakes.
Viscosity: Key to response speed.
The viscosity of the oil significantly affects the performance of hydraulic brakes, especially at extreme temperatures from -30°C to +50°C. A viscosity index (VI) of over 150 ensures a constant and rapid response of the brake.. A low VI, on the other hand, can lead to delays in cold starts of up to 0.5 seconds. The correct viscosity is a key factor in the selection of mineral oil for hydraulic brakes and equally decisive for hydraulic systems for drivetrains..
- Optimal viscosity & VI >150: For quick response at -30°C to +50°C.
- High dry boiling point (>220°C): Prevents vapor bubbles and brake failure.
- Stable wet boiling point (>160°C): Ensures performance even with aging/moisture.
- Specific additives: Protect against wear, corrosion, oxidation, and foam.
- Material-compatible additives: Gentle on seals and system components.
- Performance-enhancing additives: e.g., zinc additives for longer pump life.
Boiling point: Safety margin under extreme conditions.
The boiling point of mineral oil is a critical factor under thermal limit loads, such as those experienced with heavy presses. A high dry boiling point of over 220°C prevents vapor bubble formation and thus potential brake failure.. For long-term safety, a wet boiling point of over 160°C is also recommended even after the oil has aged. This is an important aspect of the overall hydraulics. and the specific selection of mineral oil for hydraulic brakes.
Additives: The invisible helpers for longevity.
Pure mineral oil often does not meet the high demands in industrial use. Special additives are essential; they protect against wear, corrosion, oxidation, foam formation and are precisely matched to the materials used in the system.. For example, zinc-based additives can extend the lifespan of pumps by up to 30%. Careful selection of mineral oil for hydraulic brakes consideration of the need and type of these performance enhancers is necessary.Choosing right: Making the optimal mineral oil selection for your hydraulic brake.
Manufacturer specifications: The foundation of your decision.
Manufacturer recommendations are essential for the selection of mineral oil for hydraulic brakes decision. Strict adherence to the prescribed specifications is not only a warranty issue, but directly affects the safety and efficiency of the brake system.. Using a non-approved oil in ATEK service brakes can for example reduce the holding force by up to 15%. This is also relevant for modular hydraulic units for braking systems..
Analyzing operating conditions: Load, temperature, environment.
Standard oils are not the right choice for every application, for instance in cement plants or the pharmaceutical industry. A detailed analysis of load cycles, prevailing operating temperatures (e.g. 60°C in a foundry) and specific contamination risks is crucial for the correct selection of mineral oil for hydraulic brakes selection.. For applications in the food industry, H1-certified oils are mandatory, for example. We are happy to assist you in the design of your hydraulic brake and the selection of the appropriate operating medium.
Consequences of incorrect oil selection: More than just a nuisance
The consequences of incorrect selection of mineral oil for hydraulic brakes can cause high costs. Incompatible or unsuitable oils not only lead to an increased risk of failure, but also to premature seal wear, corrosion, and reduced braking performance, which in turn can result in costly production downtime (often tens of thousands of euros per hour).. For example, EPDM seals can swell by up to 25% when in contact with unsuitable mineral oils, which impairs their function.Maximize lifespan: Optimize maintenance and care of mineral oil brake systems
Inspection and oil analysis: Proactive damage prevention
The mineral oil used in industrial brakes requires regular checks, even after careful selection of mineral oil for hydraulic brakes. Regular oil analyses (e.g., every 2,000 operating hours or annually) are essential to detect contamination by particles, an increased water content (ideally <200 ppm), or the breakdown of additives early on, before costly damage occurs.. A simple visual inspection of the oil color is an initial indicator, but it does not replace a detailed laboratory analysis. This applies to all hydraulic systems.
- Regular oil analyses: Annually/every 2,000h check particles, water (<200 ppm), additives.
- Appropriate oil changes: Every 3-5 years / 10,000-20,000h, based on analyses.
- Complete draining: Remove old oil and deposits during the change.
- No mixing of mineral oils: Different additives can be incompatible.
- Never mix with DOT: Leads to seal damage and system failure.
- Observe manufacturer specifications: For oil type and maintenance intervals.
Change intervals: Not too early, not too late
Mineral oil is generally more stable against aging than DOT brake fluids, which is why oil changes are less frequently required. Nevertheless, a change is important. Depending on the specific operating conditions and the results of the oil analyses, a change is recommended every 3-5 years or after 10,000-20,000 operating hours, to remove wear particles and aged additives from the system. A customer was able to extend the service life of his brakes by 25% through optimized maintenance, based on the correct mineral oil selection for his hydraulic brakes and adjusted intervals.
Miscibility: An often underestimated risk
Mixing oils is an often underestimated risk that can negate the benefits of a good selection of mineral oil for hydraulic brakes . Mixing different mineral oils, even if they come from the same manufacturer or have similar specifications, is risky because additive packages can be incompatible. A mixture with DOT fluids should be strictly avoided, as this inevitably leads to seal damage and system failure. Even an apparently ‘similar’ oil can critically change the viscosity of the mixture (e.g., by 10%), which impairs braking performance.Leverage system competence: ATEK as a partner for your mineral oil selection for hydraulic brakes and drive solutions
