ABSTRACT:
A steering column assembly includes a column jacket having a jacket portion and a compression bracket attached thereto. The compression bracket includes a planar wall spaced from the column portion and a sidewall extending between the planar wall and the jacket portion. The sidewall defines a telescope slot extending along a longitudinal axis. A shaft extends through the telescope slot of the sidewall. A roller is supported on and rotatable about the shaft, and in rolling engagement with the planar wall. The roller positions the shaft within the telescope slot to prevent sliding frictional engagement between the shaft and the sidewall. The rolling coefficient of friction between the roller and the planar wall is less than the sliding coefficient of friction between the shaft and the sidewall to reduce a frictional load produced during longitudinal collapse of the steering column assembly.
