iglide® M250 polymer sleeve bearing, imperial

iglide® M250 | The robust all-rounder according to DIN 2795

PFAS-tested: All iglide materials labeled as "PFAS-tested" were tested for the 96 PFAS substances considered critical for the environment and health using the SQP M1227 test method (LC-MS/MS and GC-MS) and do not contain any substances >0.1% by mass. This category excludes substances from the group of fluoropolymers.

• Over 450 dimensions available from stock
• Excellent vibration damping
• Resistant to edge loads
• High impact resistance
• Thick walled according to DIN 1850
• Dirt can become embedded for shaft protection
• Self-lubricating and maintenance-free

The self-lubricating plain bearing made from iglide® M250 distinguishes itself through its impact strength, vibration dampening and wear resistance. They excel in applications in which vibration dampening is necessary, for example, in fitness and packaging machines. Since they are additionally able to absorb dirt, they are also suited for agricultural machines and garden appliances.
 

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? For applications in wet areas When very high precision is necessary For very smooth shafts When a cost-effective wear resistant bearing is required

Tolerances and measurement system
The installation dimensions and tolerances of the iglide® plain bearings are a function of the material and wall thicknesses. For each material, the moisture absorption and the thermal expansion are imperative. Plain bearings with low moisture absorption can be designed with a minimal amount of tolerance. For wall thickness, the rule is: The thicker the bearings are, the larger the tolerances must be.
 
Assembly
iglide® bearings are press-fit bearings. The inner diameter adjusts only after press-fit in the proper housing bore with a recommended tolerance. The before press-fit oversized dimension can be up to 2% of the inner diameter. In this manner, the secure press-fitting of the bearing is achieved. Axial or radial shifts in the housing are also prevented.
