Friction and wear
Among all the iglidur® materials, iglidur® J200 exhibits the lowest coefficients of friction. The average coefficient of friction of all measurements, even with different shaft materials, is 0.11 μ. As a counter partner hard-anodised aluminium assumes special importance.
The comparison with the rest of the iglidur® materials makes it clear that iglidur® J200 bearings are suitable for rather low loads. The influence of surface speed and load on the friction coefficient is not very pronounced. The decrease of friction coefficient with the load is within the normal range (Fig. 04 and 05). Regarding the shaft surface finish, the optimum is in the range of 0.2 to 0.4 Ra. The influence of the shaft is in contrast very large in wear resistance. It is worth a look at the extensive wear data bank at low loads.
