iglide® L250 polymer sleeve bearing, metric

iglide® L250 | For high speeds
iglide® L250 is a bearing material for high rotation speeds and low coefficients of friction. The iglide® L250 material can feature these advantages particularly with low loads. Applications which feature these advantages are fans, small motors, fast-running sensors or the magnet technology.

• Specially made for fast rotating applications
• Very low coefficients of friction
• Excellent wear resistance
• Dry-running and maintenance-free
• Standard range from stock

 
Typical application areas

Automotive

 

When to use it? For rotating applications at high speed If highest service life is required Low load applications If low noise level is required For very low coefficients of friction

When not to use? If high pressure occurs When sustained temperatures above +194 °F is a condition When low moisture absorption 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.
