iglide® TX1 proved to be the favorite for edge loads
At a customer's request, the motion plastics® specialist igus® compared iglide® and brass bearings with each other in a wear test at the in-house laboratory. In the customer's heavy-load application, a surface pressure of up to 1,233 psi and an overturning torque of 37,000 Nm act on the bearing For this purpose the test parameters were converted to the dimensions of the bearings to be tested.
Diagram 1: Wear due to edge load; p: 10 MPa (1,450 psi) + edge load; v: 0.05 m/s (0.16 ft/s); ß: 32.5°; lubricated
The tests in the igus® laboratory show that the iglide® TX1 bushings have considerably less wear than the brass bearings The average wear rates in diagram 1 are therefore considerably lower. The lowest values are shown by iglide® TX1 with hard-chrome-plated Cf53 shafts but, with the special customer shafts as well, the wear in the tests is still better than that of the brass bearings by a factor of 6.
A = cf53 hc B = Customer shaft C = iglide® TX1 D = Brass bearing
Conclusion:
The iglide® TX1 has a lower wear rate compared to the brass bearing against both tested shaft materials. In addition, the brass bearings showed severe plastic deformation and a break. Regardless of the tested shaft material, iglide® TX1 proved to be the most suitable material for this application with extreme edge loads.
dry-tech® test laboratory
In the dry-tech® test lab over 135 trillion tests are performed each year
Tribopolymers developed for dry-running conditions.
igus® develops polymer materials that solve new bearing tribology application problems. Base polymers, solid lubricants and reinforcing materials are combined to create the perfect bearing properties.
These are proven with constant testing in our laboratories.
