Abstract: A vibration damper comprises a rigid inner member having a plain cylindrical outer surface, a rigid outer member having a plain cylindrical inner surface located in generally concentric relation with the cylindrical outer surface of the inner member, and an intermediate moulded ring of elastomeric material inserted between said cylindrical surfaces so as to be radially compressed therebetween. The elastomeric ring has outer and inner generally cylindrical surfaces contacting the inner and outer plain cylindrical surfaces of the outer and inner members respectively. At least one of the said inner and outer surfaces of the elastomeric ring is formed with a moulded textured finish with peaks and troughs such that the differential between the peaks and troughs in the textured surface is in the range of 250 to 1000 micro inches.
