Data sheet


Wieland-S40 By adding Al, Mn and Si, special brass with very high load capacity, good corrosion resistance and good sliding friction coefficient.
Hardened shafts are recommended for higher loads. Used wherever high forces are combined with shocks, e.g. excavator joints, steering knuckles, etc. Furthermore in slip clutches, as valve guides in car engines and power lift bearings in tractors.
