Offering self-lubricating and maintenance-free properties for heavy-duty applications, the TX2 bearing increases wear resistance by a factor of 3.5 in. load ranges with more than 100 MPa surface pressure. The material is ideal for components in machines that serve construction and agriculture, which can require more than 50 liters of lubricant annually.
The TX2 material offers an alternative to frequently used metallic solutions with its plain bearing technology. Another material combination for wound bushings complements the range of injection-molded bearings in the heavy-duty range.
The tribo plain bearings made of high-strength filament fabric are used where very high loads occur. The extremely strong filament in its specially interwoven design ensures maximum resistance and enables a maximum permissible compressive strength of 400 MPa. The newly developed material was extensively tested on the indoor and outdoor test rigs in the 3,800 square-meter igus test laboratory.
Pivot tests on hard-chrome shafts showed that iglide TX2 is around 3.5 times more wear-resistant than the standard heavy-duty material TX1. Like all iglide plain bearings, iglide TX2 is self-lubricating and operates dry. This prevents dirt from adhering to the bearing points. This reduces maintenance and repair costs, as well as machine failures due to insufficient lubrication.
As the material is also very resistant to temperature, chemicals, and moisture, plain bearings made of iglide TX2 can be used in many other areas. Diameters of up to 2,800 mm are feasible.
