The TX2 bearing has an improved iglide material, which o ers self-lubricating and maintenance-free properties for heavy-duty applications. The TX2 increases wear resistance by a factor of 3.5 in load ranges with more than 100 MPa surface pressure. The material is suitable for components in machines that serve construction and agriculture, requiring more than 50 liters of lubricant annually. These tribo plain bearings made of high-strength fi lament fabric are used where very high loads occur. The robust fi lament, 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.

Hybrid bearings for tough industrial applications
NKE nke.at
These hybrid bearings consist of ultrapure steel bearing rings and ceramic rolling elements made of bearing grade silicon nitride Si3N4. “At fi rst glance, this material pairing is highly unusual, but it o ers many advantages in an enormous range of applications, which signifi cantly increases the reliability of the overall system,” says Michael Rössl, Application Engineer at NKE in Steyr, Austria. The silicon nitride rolling elements are 60% lighter than those made from steel and are suitable for high rotating speeds. These hybrid bearings can reach limit speeds that are over 20% higher than conventional standard bearings. Even at these high and demanding speeds, NKE hybrid bearings demonstrate strong performance characteristics and minimal running noise. They are particularly well-suited for high-speed electric motors. The ceramic rolling elements have high wear resistance and can achieve better results under demanding conditions, such as poor lubrication, extending service life signifi cantly.
