iglidur® Q290: Long life even on soft shafts and high loads

… good to shafts … … in case of heavy duty

highload material  

Especially with medium to high dynamic loads, this material demonstrates its strengths: In rugged pivoting applications excellent durability can be achieved for shaft and bearings, e.g. in agricultural or construction machinery, and then specifically on "soft" shafts!
 

Long life even on soft shafts

Insensitive to edge loads

Continuous up to 140℃

Good cost/performance ratio

Lubricant- and mainteance-free

Standard program from stock


 
Typical applications: front loader, connections of hydraulic cylinders, undercarriages, hydraulic platforms
