iglidur^® M250 | The Robust All-rounder according to DIN 2795, Flange Bearing (Form F)

Product Information

Excellent vibration dampening
The self lubricating plain bearings made from iglidur^® M250 are defined by their impact strength, vibration dampening, and wear resistant properties. They excel in applications in which vibration dampening is necessary, for example, in fitness and packaging machines.
When to use it?
• When the bearings are exposed to high amounts of dirt
• When high vibration damping is necessary
• For low to medium speeds
• When mechanical reaming of the wall surface is necessary
• Resistant to edge loads
• High impact resistance
• Thick walled according to DIN 1850
When not to use it?
• For applications in wet areas
►iglidur^® H
• When very high precision is necessary
►iglidur^® P
• For very smooth shafts
►iglidur^® J
• When a cost-effective wear resistant bearing is required
►iglidur^® R
Typical application areas
• Agricultural machines
• Furniture/Industrial design
• Textile industry
• Doors and gates
• Machine building
