Friction mechanical components

To complete the wide range of bushings and to offer our customer a maximum efficiency of the articulation, HEF DURFERRIT has thus developed a range of shafts, sleeves or washers providing ts customers a global solution with superior performances.

As a solution provider in field of tribology, our experts design and solve troubles thanks to their knowledge in surface treatment, in choice of material and contact lubrication. Several pins dedicated for extrem applications could be recommended when using HEF bushings. PEL® OX, PEL OXC, PEL® STC, FAM® OX or ST.

They combine an high core hardness (> 850 MPa) and a surface treatment which provides suitable properities against wear, fretting corrosion and good for pin disassembly. Special polymer coating or varnish could improve the friction properties too.
