18 it will be understood that the snubber 100 c is mounted to the side of the e block 20 a by way of a suitable fastener 118 which preferably inserts through a hole not shown in the snubber 100 c and engages with a corresponding threaded hole also not shown in the e bock 20 a it will be recognized by those skilled in the art that in actuator designs that use a screw to secure the bearing cartridge not separately designated but surrounding the pivot shaft 22 this screw can also serve as the fastener 118 shown in fig6 to secure the snubber 100 c to the e block 20 a an important advantage of the snubber 100 c is that the protection provided by the snubber arms 102 c is generally maximized by the adjacent placement of the snubber arms 102 c to the actuator arms 24 although not shown in the drawings it will be recognized that the configuration of the snubber arms 102 c can be modified as desired to account for the rotary movement of the e block 20 a relative to the discs 18 to minimize the radial extent of the snubber arms 102 c into.
