iglide® A160 - Material data

iglide® A160 plain bearings are characterized by extreme media resistance at a low cost. Tribologically optimized, the material can be used in up to +194°F and also possesses conformity demanded in the food processing sector. The property profile is rounded out by its "visual detect-ability" - e.g. the blue color frequently demanded by the industry.

Mechanical properties

With increasing temperatures, the compressive strength of iglide® A160 bearings decreases. Fig. 02 clarifies this connection. Maximum recommended surface pressure represents a mechanical material parameter. Tribological conclusions cannot be drawn from it.
 
Figure 03 shows the elastic deformation of iglide® A160 with radial loads. Under the maximum recommended surface pressure of 2,176 psi, the deformation amounts to less than 3,0%. A plastic deformation is negligible up to this radial load. It is however also dependent on the period of exposure.

Friction and wear

Coefficient of friction and wear resistance alter with the application parameters. In the iglide® A160 bearings, the alteration of the friction coefficient µ dependent on surface speed and the shaft's surface finish is only negligently pronounced. However, the friction value drops significantly as the load increases. The ideal surface roughness of the shaft in relation to the friction value is at 0.6-0.7 Ra.

Shaft materials

Figure 06 displays a summary of the results of tests with different shaft materials, which were conducted with iglide® A160 plain bearings in dry operation. For rotational applications with low loads, the most interesting media- and corrosion-resistant shaft materials V2A, X90 and hard chrome-plated steel reveal themselves as good counter-partners. On X90 shafts, however, the wear increases the fastest with the load (Fig. 06). With Cf53 shafts, the wear in swiveling applications is exemplary compared to rotating applications. In rotation the wear, as with many other iglide® materials, is higher than in the swiveling.
