iglidur^®W300 | The Classic Endurance Runner up to 30 MPa, Flange Bearing (Form F)

Product Information

Excellent wear resistance on (virtually) all shafts
The iglidur^® W300 material gives excellent wear resistance, even in harsh environments or when used with rough shafts. Of all iglidur^® materials, iglidur^® W300 is the most resistant to these conditions.
When to use it?
• When especially high service life is necessary
• When low coefficients of dynamic friction and high wear resistance are needed
• For use on 304 stainless steel shafts
• For harsh environments and very rough shafts
• Dirt resistant
When not to use it?
• For high loads starting at 50 MPa
  ►iglidur^® Q
• When constant temperatures exceed +90°C
  ►iglidur^® H
  ►iglidur^® X
• For very wet environments
  ►iglidur^® P
• When an economical bearing is required
  ►iglidur^® G
Typical application areas
• Automation
• Printing industry
• Woodworking
• Mechatronics
• Test engineering and quality assurance
