Wear testing for customer

iglidur® J350 against PPA GF-30 shafts

The iglidur® J350 material was tested for a customer from the automobile industry. In addition to the required temperature and media-resistance, the primary reasons were good wear-resistance against the PPA GF-30 plastic shaft used by the customer.
 
The igus® test lab conducted a wear test using the customer's original shaft material under the following conditions to explicitly test the good suitability of iglidur® J350:

Test configuration

Load: 16 N

Pivot angle: 20°

Speed: 2 Hz ≙ 0,007 m/s

Temperature: 50% of time 150°C; 30% of time 120°C; 20% of time room temperature

Operating time: > 800.000 cycles ≙about 3 km

Test configuration

The two test rigs used to conduct the tests. The installed bearing supports can be heated to permit temperature control.

 

Test results

The bearings exhibit very little signs of friction.
