Yoke type and stud type track rollers in X-life quality

Robust bearing supports, longer operating life.

Yoke type and stud type track rollers are often used for transmitting high radial loads. As X-life yoke type and stud type track rollers, they make a convincing case through even higher performance capability.

By changing the materials and optimizing the raceway geometry in the outer ring, the basic rating life has increased by up to 30 percent. Dynamic and static load carrying capacity was also increased. In addition, the optimized outside surface profile and its improved surface quality on the outer ring reduces the stress on the mating track This results in a very robust bearing support with longer operating life and higher reliability in the application.

Yoke Type and Stud Type Track Rollers now even more efficient PWKR and PWTR series.


Advantages of X-life quality

  • Up to 30% higher static and dynamic load carrying capacity due to optimized raceway geometry.
  • Higher permissible ring load by changing the material of the outer rings.
  • Improved outside surface quality by optimizing the surface structure.
  • Increased protection against corrosion due to Corrotect® coating.
