COD 11® bearings are manufactured from a copper aluminum alloy with excellent resistance to oxidation, to seizure and wear thanks to a hardened surface treatment and to grease reservoirs on the contact area.
Thanks to different surface topography, the intervals of lubrication on COD 11® bushing with cross hatching or COD 11® BH bushings with cavities are considerably increased.
This COD 11® technology is also availiable for slide, washer, etc.

For optimal performances of the joint, the surface roughness should be inferior to 0.8 μm Ra. Under severe working conditions, shafts hardened ≥55 HRC or ≥ 600 Hv1 are recommended.
For optimal performances, special shafts are available from HEF DURFERRIT : COD® ST, COD® STC, COD® OX, for marine applications : in sea water environment, we recommend COD® EM shafts.
