Iglidur light polymer plain bearings from Igus have been used in the design of the Contrail MGN full-suspension mountain bike from Bergamont. The bearings help to handle the severe stresses of the rear suspension.

Bergamont, which originally used ball bearings for all the bike’s bearing points, is using plain bearings on the rear axle as these offer a much larger contact area than roller bearings and so perform well with the high-pressure loading at this bearing point.

Igus advised Bergamont on the optimal bearing material and supported a range of tests, first using Iglidur G, which offers a broad range of applications at an economical cost, and then using Iglidur J, which proved to give higher performance with greater dimensional stability when tested in the wet conditions that the Contrail MGN would experience.

Key benefits of product application

  • Wet conditions are not proving to be a problem for the polymer plain bearings.
  • Self-lubricating Iglidur polymer plain bearings offer long and reliable service life.
  • Torsional stiffness of the wheel is very good and suspension responds quickly.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
