psl® rolling bearings – 70 years of excellence

Rolling bearings are machine elements that enable a rotary motion and absorb loads between rotating and stationary parts of machines. They absorb radial, axial or both forces depending on the design. The rolling elements minimize friction during rotation due to the small contact surfaces of the rolling bodies between the inner and outer ring.

Under the psl® brand, thyssenkrupp rothe erde manufactures a wide range of rolling bearing types such as:

  • axial,

  • tapered,

  • cylindrical,

  • toroidal and

  • spherical.

Our competence in the field of design, development and production of rolling bearings is based on tradition and experience in the bearing industry. The products are developed, designed and manufactured solely by our Slovakian subsidiary located in Považská Bystrica, Slovakia.

For more than 70 years, we have supplied our psl® products all over the globe. Our brand and products are well recognized by customers in many industrial areas worldwide.

Applications of our products include:

  • state-of-the-art machine tools of high precision

  • heavy industrial plants for mineral processing

  • large telescopic antennas for space research

  • railway gearboxes

  • power transmission systems

  • wind turbines

As a well-known and reliable rolling bearing manufacturer, we want to offer our customers a wide spectrum of products. Our product portfolio includes various sizes: The smallest bearings have an inner diameter of 120 mm, the largest an exterior diameter of 3,400 mm.

To be able to meet the requirements of the market, we are continuously developing our product range. If you have a question or special request, please contact us here.

For our production process, we make sure to procure quality materials from renowned manufacturers and ensure the compliance with quality standards.

We produce the main components in our own facilities: bearing rings, roller elements and cages. This allows us to monitor and guarantee the high quality of our products at all stages of the production. The way the components are being machined depends on their shape, the materials used and the final properties required. When managing the entire design, development and production process, we rely on an established and certified quality management system according to the ISO 9001: 2015 standard. Filing records from individual production and control operations for potential use in the future is a must.

inductive hardening

In order to achieve the final performance characteristics of the bearing and its reliable function during the intended service life, the correct choice of materials of individual bearing components and the method of their heat treatment is extremely important. With the ever-increasing demand for larger rolling bearings, the factor of economically efficient production plays an extremely important role. We are proud to be able to offer our customers a wide variety of traditional and new methods of heat treatment and hardening including a patented inductive hardening procedure without a soft spot.
