The steer-by-wire steering system also includes an anti-rotation cartridge comprising a sleeve containing separate wear plates in which a plurality of ball bearings roll, wherein a first end of the sleeve contains a sleeve groove and window features, the inner surface of the sleeve containing V-shaped grooves in which the wear plates are disposed.

Abstract: Exercising apparatus (10) including a seat (21) on which a user (U) is seated for exercising, a rear tensioning device (24) positioned behind the seat (21) and mounted for movement between opposed sides of the user (U), and a front tensioning device (28) in front of the seat (21) mounted for movement on a pivotally mounted leg (32) between opposite sides of the user (U). Flexible cables (26, 30) extend from the tensioning devices (24, 28) and are connected to a cuff (22) about the ankle of the user (U). The force exerted through the flexible cables (26, 30) may be adjusted by manual setting of a rotatable knob (102) on the tensioning devices (24, 28) which increases the resistance to unwinding of the cable (26, 30) from its associated drum (77) of the respective tensioning device (24, 28).
