Uplift, Movement & Rotation. Simultaneously.
The pin acts much like a trailer hitch connecting a trailer to its vehicle. The expansion bearing’s upper slide plate is also modified so that it lips under the upper bearing in order to resist uplift force. Fully assembled, the modified Disktron Bearing can accommodate uplift load, movement and rotation simultaneously—a feature unique to this type of bearing.
