AMPEP X‐1 AN IMPROVED BEARING MATERIAL

THE Fiberslip range of woven ptfe bearing materials, manufactured by Ampep Ltd, Clevedon, Avon, is well known in many fields and especially to aerospace designers. Demand for ever better improvements in bearing performance, particularly in helicopter rotating assemblies has led to a development programme to improve wear resistance and bedding‐down characteristics and this was undertaken by Ampep with collaboration from the Materials Department of the Royal Aircraft Establishment and the Materials Branch of the Ministry of Defence.
