Why Bearing Failures Occur in Industrial Systems

Up to 40% of industrial machinery breakdowns are linked to bearing issues¹, often caused by two avoidable mistakes:

Incorrect material selection
Use of standard catalogue bearings in non-standard conditions

This results in increased wear, reduced service life, and unplanned system downtime.

Industries

In aerospace, every component has to perform under extreme conditions: high speeds, vacuum, and fast-changing temperatures, with no room for error.

Our ceramic bearings are engineered for exactly these challenges. They are lightweight, so they handle high speeds with less strain. They maintain precision under rapid thermal changes and perform reliably in vacuum conditions, where standard steel bearings often fail.

This is why our high-performance ceramic bearings are trusted in zero-gravity flight testing and have even been used in the first wheeled vehicle to operate on Mars.

Industrial machinery is expected to operate continuously with minimal downtime. Standard steel bearings often wear out faster under heavy loads or inconsistent lubrication, leading to costly production stops.

Turbo pumps operate at extremely high speeds, often with limited lubrication. Standard steel bearings quickly generate heat and wear under these stresses.

Our ceramic bearings are designed for high-speed, low-lubtrication environments. Their low weight and excellent dry-running properties reduce heat generation and wear, enabling higher speeds and longer operating life.

In the chemical industry, components are continuously exposed to aggressive media such as acids and alkalis. Steel bearings are highly susceptible to corrosion in these environments.

Our ceramic materials, including silicon nitride and zirconium oxide, offer outstanding chemical resistance. They maintain strength and precision even under continuous exposure to corrosive substances. In many cases, the process fluid itself can act as a lubricant, eliminating the need for additional lubrication systems.

Metalworking processes involve very high temperatures where lubricants degrade and steel bearings lose performance.

Our ceramic bearings are designed to handle this heat. They maintain their strength and precision at temperatures up to 1,000°C and beyond, so your equipment keeps running smoothly even in the most thermally demanding parts of your process.

Pharmaceutical production demands strict hygiene standards. Even a small trace of lubricant or wear particles can compromise entire batches.

Our full ceramic bearings operate dry or with minimal lubrication, are chemically inert, and do not release metallic particles. This makes them ideal for reactors, dosing systems, and cleanroom production environments.

Medical devices require non-magnetic, electrically insulating, and contamination-free components, especially in imaging systems and patient-facing equipment.

Our ceramic bearings meet all of these requirements naturally. They are non-magnetic, electrically insulating, and manufactured to the strict cleanliness standards medical applications need, making them a dependable choice for precision medical devices and laboratory systems.

Food and beverage production requires frequent cleaning and strict hygiene compliance. Standard steel bearings can corrode or trap contaminants under these conditions.

Our ceramic bearings resist corrosion from cleaning agents and moisture. They operate without oil-based lubrication, reducing contamination risk, and withstand repeated washdown cycles, supporting both hygiene and long-term equipment performance.

Measuring and calibration systems depend on absolute stability. Even minimal thermal expansion or bearing play can throw off a reading.

Our ceramic bearings expand less than steel when temperatures change, and they maintain tighter tolerances over time. This keeps your instruments precise, even as conditions around them change.

Semiconductor manufacturing and biotech cleanrooms require strict contamination control. Lubricant residue or particles from a worn bearing can disrupt sensitive processes.

Our full ceramic bearings can operate completely dry and do not release particles like worn steel bearings. This makes them one of the few bearing solutions suitable for cleanroom-grade, contamination-free applications.

How We Define Bearing Performance

Selecting the correct ceramic material determines resistance to heat, wear, corrosion, and mechanical stress. Each ceramic material offers distinct mechanical, thermal, and chemical properties suited to specific operating conditions.
