Bearing points on construction and agricultural machinery can be
free of lubrication and maintenance with iglidur M210 and M260 materials

Save time and costs on bearings
for machinery medium loads with iglidur M210 and M260. These materials enable
heavy machinery like construction equipment to switch from thick-walled metal
bearings to plastic bearings with no structural modifications. The bearing
points no longer require lubrication and are almost maintenance-free. The
plastic bearings offer a significant time and cost advantage, especially in
harsh environments in the daily operation of construction, agricultural and
municipal machines.

The new iglidur M210 and M260
plain bearings have wall thicknesses of up to 5mm and inner diameters of 20,
25, 30, 40, 50 and 60mm. They are particularly suitable for applications with
pivoting movements in the medium load range from 20N/mm², where the
quick replacement of thick-walled metal bushings is required without structural
modifications; for example in construction and agricultural machines and
municipal vehicles that must withstand harsh environmental conditions each day.

The two materials differ slightly
and have different advantages when interacting with various shafts, for
example, the M260 variant achieves excellent wear results in combination with
shafts made of St37 steel.

Less maintenance and cleaning needed, more environmental protection

Switching from metal to polymer bearings means significant cost and time savings, especially for machines and vehicles with many bearing points as lubrication is no longer required. The tribological plain bearings in M210 and M260 are self-lubricating. Solid lubricants ensure low friction and dry operation and significantly reduces cleaning, as dirt and dust cannot stick to any greasy lubricant. Another advantage is environmental protection as no lubricants are released. The power consumption of machines and systems that use these bearings is also reduced because plastic bearings are lighter than metal bearings.

Robust and lightweight

To guarantee sufficient strength and robustness of the iglidur M210 and M260 plain bearings, material experts at igus strengthen the polymer materials with fibres and fillers to so that they can withstand high surface pressures of up to 40MPa – and even at temperatures between -100°C and +140°C.

Tests in igus’s laboratory prove that the polymer bearings show limited visible wear in pivoting movements at medium loads, even after several thousand cycles. “For this application, the front loader test stand in the outdoor premises is used,” says Stefan Loockmann-Rittich, Head of the Business Unit iglidur plain bearings at igus. “In addition to standard tests, application tests are vital in material development. All test results then flow into iglidur online experts, an online selection tool where the service life of M210 and M260 can be calculated using precise specifications.”
