voids 136 although voids of other shapes may be similarly formed the voids 136 may form a honeycomb like body of the elastically deformable body 130 alternately the elastically deformable body 130 may be formed without voids the elastically deformable body 130 may be formed as a rubber pad from a natural or synthetic rubber suitable for use in contact with or immersed in fluids commonly found in an automotive transmission environment for example natural or synthetic lubricating oils used in automotive engines or transmissions in non limiting examples the elastically deformable body 130 may be formed from alkyl acrylate copolymer acm or other materials suitable for contact with the fluids similar to those described above in a temperatures range of about u2212 40 degrees c to 140 degrees c the elastically deformable body 130 may have a shore hardness of between 40 and 80 for example 60 in some embodiments one or more of the lower or upper surfaces 138 140 of the elastically deformable body 130 may be formed with a pattern of raised surfaces for example ribs or bumps extending away from the top surface 140 of the elastically deformable body 130 a chain guide 150 is disposed on the upper surface 140 of the elastically deformable body 130 with an outwardly facing sliding surface 156 the chain guide 150 is adapted for attachment to the arm 102 with the elastically deformable body 130 disposed between the.
