Front-loader test rig from igus tests durability of plastic versus metal

October 19, 2017 By Mike Santora

PM4717-1The igus test laboratory is 29,600 square feet, quite possibly the largest in the industry. Inside, the movements of energy chains, chainflex cables and plastic bearings are continuously assessed. The newest addition to the igus laboratory is a front-loader test rig, made specifically to mimic applications in the agricultural and construction equipment industries that handle high loads. Numerous bearing and shaft combinations are being tested outdoors under conditions mimicking real application challenges. Direct comparisons of plastic and metal bearings are also being tested.

High-load tests assess durability
The current surface pressure of the test rig is between 3191 and 4,279 psi, depending on the bearing point (4,279 psi approximately corresponds to a load of 2,645 lbs on a bearing with a diameter and length of 20 millimeters). Tso find the optimal bearing and shaft combination or the most suitable iglide triboplastic material, the load to be lifted can be increased from 550 to 1,100 pounds. Four cycles are completed per minute, although the resulting speed depends on the pivoting angle of the respective bearing point. The test lasts for about two weeks. Daily visual inspections are also conducted to ensure that the front loader is not damaged if a bearing point failed.

Aside from in the test rig, iglide bearings are also proving their strength and durability in wheeled loaders made by the company F.X.S. Sauerburger, where iglide bearings have been in use in the lifting arms for over ten years. A surface pressure of approximately 3,045 psi acts on the iglide bearings in the lifting arm, which the plastic bearings deal with without issue. The self-lubricating bearings are also impervious to wind, weather, dirt, and other common environmental factors.
