iglidur® Q290: New dimensions for the lubrication-free shaft specialist at high loads

... Heavy-duty on soft shafts ...

Q290  

Double the size of the dimension range for maximum service life in high-load applications with "soft" shafts (for example, galvanised).

Long life mainly on soft shafts

No Shaft wear

Insensitive to edge loads

Continuous up to 140℃

Good cost/performance ratio


Typical applications:Agricultural engineering, utility and construction vehicles

5x better wear rate and no break-in on the shaft

p > 50 MPa | v = 0.01 m/s
