Highly wear-resistant and fire-resistant

For rail technology

With DIN EN 45545, the new material iglide® RW250 meets the strict fire protection requirements of railway technology. In addition, the material formulation has been optimized for complete wear resistance and offers excellent running properties in many applications.  ​

Cost down

  • Maintenance-free
  • Higher running performance



  • Lasts up to 3x longer than RW370 (test: oscillating motion, load 290 psi, speed 1.97 fpm, 73° F, shaft 440B stainless steel)



  • Environmentally friendly, because no external lubricants are required.
  • Good coefficient of wear and therefore long service life.

Safety for railway technology

We have developed iglide® RW250 for this purpose

The highest safety requirements apply to public transport vehicles in local and long-distance traffic. One of them is the fire protection standard DIN EN 45545 for rail vehicles.  ​

Plain bearings, which are used in the numerous mechanisms for seats, levers, flaps and doors, must meet these requirements in order to avoid endangering passengers if the occasion arises.  ​


These - quite legitimate - strict specifications pose great challenges for materials development in bearing technology. In addition to the plain bearing material iglide® RW370 already established in the industry, we have developed an even more cost-effective and wear-resistant material in the medium load range called iglide® RW250 . ​
