Oxafen inserts are used in various components of construction machines: crane boom suspension assemblies, bearings of transverse motion sliders of attachments and safety couplings of gears of chain excavators, backhoe loaders, etc. Bench tests and subsequent long-term performance tests confirmed the advantages of using Oxafen and Oxafen OPM-94 composite materials for making bushings instead of bronze (e.g. BrA7, BrO5Ts5S5 bronze etc).
