Material:
Shim washers: steel St 2 K 60 (strength 600-750 N/mm²)
Support washers: spring steel HRC 44-49.
Finish:
From 2 mm thickness upwards, side faces are ground. Single thickness deviations are within the thickness tolerance.
Surface:
To manufacturer's choice
Shim washers:
- Self-finish and oiled
Support washers:
- Self-finish and oiled
- phosphated and oiled
Please note:
The thickness values specified in the data charts apply to the self-finish and phosphated washer versions. If special versions of washers with different surface coatings are supplied, these dimensions will be increased by the corresponding coating thickness.
Important:
The thickness tolerances of washers with thickness of 1.2/1.5/2.0 mm deviate from DIN 988. The 15 x 22 washers and the washers from 100 x 125 onwards are not covered by DIN 988. The same applies to shim washers with thickness of 0,15 and 0,25 mm.
