Axial deep groove ball bearing (KT bearing)

Optimal Bearing Solution for High Axial Loads

Our single-direction, single-row axial deep groove ball bearings (KT bearings) offer a reliable solution for high axial loads combined with slow rotational or pivoting movements. Their compact design and precise manufacturing make them ideal for demanding industrial applications.

Design and Function of KT Bearings

KT bearings consist of two precisely machined thrust rings, a matching housing, and robust rolling elements. In the standard version, the thrust rings are made of case-hardened steel. The special construction ensures high axial stiffness and a long service life with consistent performance.

Applications of Axial Deep Groove Ball Bearings

Typical applications for KT bearings include:

  • Automation technology
  • Swivel units and robotic joints
  • Assembly fixtures
  • Machining equipment
  • Tool and jig construction

Housing Materials – Versatile and Adaptable

Depending on the operating environment and technical requirements, the housings of KT axial bearings are available in various material versions:
