Roller bearings

Over 90 Years of Expertise in Bearing Technology

In 1933, Artur Küpper founded his company in Velbert-Tönisheide. Over time, the brand name AKT has become synonymous with high-quality track rollers and roller bearings. Today, the company is successfully managed in the third generation by Mrs. Susan Küpper.

Custom Bearing Solutions – Engineered for Your Needs

Far beyond Germany’s borders, AKT is recognized as a global competence center for customer-specific bearing solutions. Our products are used wherever movement, rotation, or transportation under challenging conditions is required.

Whether for high temperatures, corrosive environments, or limited installation space – our customized bearings are developed to meet specific technical requirements and ensure long-lasting reliability.

This video provides an exclusive insight into our modern production environment – from precision turning and grinding to automated assembly of customer-specific bearings.

Individual Support and Long-Term Partnerships

At AKT, close cooperation and personal support are essential. We accompany our customers through every phase of their project – from initial consultation and technical design to production, assembly, and final quality control.

Our in-house portfolio includes tailor-made bearing types and integrated bearing units with unique performance characteristics. These provide measurable and lasting competitive advantages across a wide range of industries.
We look forward to receiving your inquiries.

Bearings for extreme temperatures

In many customer applications with high temperatures (over 200°C), standard bearings will not fulfil the given requirements. These extreme conditions require an adapted bearing design with a special heat treatment and well-chosen construction materials. Especially the choice of matching high-temperature lubrication and the correct calculation of the re-lubrication intervals do indeed play a fundamental part for a long bearing lifetime under these conditions.

Bearings / track rollers with Corrprevent

The functional capability of the bearings and track rollers is mostly influenced by the conditions of their running surfaces. Beginning corrosion and increasing wear are the main reasons for an early bearing failure. They are mostly caused by the coaction of aggressive detergents and moisture in areas with temperature fluctuations. The Küpper Corrprevent coatings protect our products from external influences and increase their life time.

Sealing systems for bearings / track rollers

Insufficient sealings have a large share in the main reasons for bearing failures. The requirements on a sealing system for bearings can be very versatile and must therefore be accurately examined for each type of product and environmental conditions. The sealing systems developed by Küpper offer a permanent protection for your bearings and track rollers even under extreme conditions.

Tailored solutions for bearing applications

Standard bearings often do not meet market requirements for ongoing performance enhancements, which is why we create customized solutions for specific demands. By merging various machine elements into an assembly group, we create systems tailored to our customers’ demands with higher performance, fewer downtimes, and reduced maintenance efforts with only minimal space requirements.

Optimised profile shapes for track rollers

For many installation situations, the critical factor is not the load rating of the bearing arrangement within a track or yoke type track roller, but the insufficient wear resistance in the contact area between the outer ring and the rolling partner (rail). The outer rings, which are usually thick-walled, can lead to premature wear on the rolling partner and thus to failure of the entire units if the profile shape is selected incorrectly.
