Abstract
A roller assembly for guiding the motion of a circumferentially extending ring in a gas turbine engine, where the roller assembly has a pin and a collar. The pin has a head which engages a rotatable element, which in turn adapts the roller assembly to engage a track and which adapts the roller assembly to receive an external force from the track under operative conditions, causing a reactive force on the rotatable element to resist the external force. A gap formed between a shank of the pin and the collar decreases the bending stresses in the shank in comparison to forces acting on the pin at an end of the collar which engages a support.
