Plain bearings are often subject to extreme conditions
such as heavy loads in construction machines, agricultural equipment, utility
vehicles and offshore installations. To address this requirement, igus has upgraded
their lubrication-free two-component bearing iglidur Q2E. The iglidur Q2 material
has been tested to withstand a high degree of wear, while a hard polymer shell
protects the heavy-duty bearing.
impact and high edge loads
Bearings in construction equipment, agricultural
machines and offshore installations often have to cope with extreme conditions,
calling for the use of durable materials and dirt-resistant components. igus
has now upgraded their iglidur Q2E heavy-duty bearings for exactly such
Treotham is expanding its range of bearings for
heavy-duty applications and closes the gap between existing bearings and
solutions made of metal and composites. The bearing consists of
high-performance plastics and is, therefore, completely lubrication- and
corrosion-free. The absence of lubrication allows maintenance-free operation of
the bearing points and prevents machine failures from lack of lubrication.
Expensive central lubrication systems are no longer necessary. Dirt and
impurities can no longer adhere to the bearing points, minimising wear.
In addition, less grease and oil escape into the
environment, reducing the annual consumption of over 35 million metric tons of
lubricant, as measured by RWTH Aachen University. Also, the injection-moulding
method used to manufacture the plain bearings is especially cost-efficient.
combination is the secret
Two materials in an encapsulated design ensure that
the bearing can cope even with the most extreme edge loads. This is because the
iglidur Q2E has a hard polymer shell and a tribologically optimised core
composed of iglidur Q2 as the material. When used for a plain bearing with a
diameter of 20 millimetres, this material is also very dimensionally stable and
wear-resistant even under high loads of up to 7 metric tons.
Functioning as a protective sheath, the shell makes
the bearing very sturdy and ensures that it has a longer service life. igus has
proven this in their own in-house test laboratory. In the swivel test, the
material withstood a radial load of 130 MPa. iglidur Q2E is initially available
for shaft diameters of 20, 25, 30 and 40mm from Treotham Automation.
