Brands in the Spotlight: INA
When it comes to precision motion and engineered reliability, INA is a name that comes to the forefront. As one of Schaeffler Group’s core global brands, INA has become synonymous with innovation, accuracy and long-term performance; qualities that align perfectly with what engineers and machine builders expect from modern linear systems. Today, we’re putting INA in the spotlight and exploring what makes this brand such a trusted choice across industries.
Who is INA?
INA’s story stretches back to 1949, when Dr. Georg Schaeffler developed the first cage-guided needle roller bearing, an invention that fundamentally reshaped bearing design. The brand’s name, Industrie-Nadellager, literally means “industrial needle roller bearings”, but Schaeffler himself liked to say that INA stood for “Immer Neue Aufgaben”, “always new tasks”. It’s a perfect reflection of the brand’s mindset: curious, adaptable and relentlessly focussed on how motion technology can improve machines.
Today, that original spark of innovation sits at the heart of a much broader range of products. INA hasn’t stopped evolving; it has scaled to global prominence and now forms one of the three pillars of the Schaeffler Group, alongside FAG and LuK. That integration brings together precision bearing technology, advanced manufacturing expertise and a commitment to supporting customers through every challenge.
What Does INA Offer Today?
Although INA is widely known for its needle roller bearings, its portfolio now spans a full spectrum of high-performance solutions, particularly in linear motion. Customers can depend on INA for:
- Linear guide rails
- Linear bearings
- Linear slide
- Linear bearing units
- Complete linear modules
- Cross roller bearing
- Linear shafts & supports
These systems are built for accuracy, smoothness and consistent operation, even under high loads or continuous cycles.
Beyond linear technology, INA also manufactures rolling bearings, spherical plain bearings, housing units and a variety of precision components used in automotive engines, transmissions and industrial machinery. What ties everything together is the
brand’s focus on friction reduction, reliability and efficient engineering. Every product is designed with longevity and performance in mind, helping operators reduce downtime and enhance output.
Why Engineers Choose INA
One of INA’s biggest strengths is its commitment to continuous improvement. The brand’s x-life range is a standout example, engineered to deliver reduced friction extended service life and higher load capacity. These enhancements aren’t just incremental; they make a genuine difference to machine reliability, cost efficiency and return on investment.
Customers also value INA’s consistency. With decades of expertise and a global manufacturing footprint, Schaeffler ensures that every INA product meets strict quality standards. Whether it’s a compact bearing or tight installation spaces or a linear rail required for clean-room precision, engineers know they’re choosing components built with care, accuracy and real-world conditions in mind.
Over the years, INA products have found their way into manufacturing plants, robotics, packaging machinery, automotive production lines and countless engineered systems. Wherever reliability matters, INA delivers.
A Closer Look at INA Linear Systems
