iglide® UW160 polymer sleeve bearing, metric

iglide® UW160 | KTW-compliant, suitable for contact with drinking water
 

• Extremely wear-resistant in liquid at long-term operation
• Suitable for contact with drinking water (KTW-compliant)
• Good liquid media resistance
• Dry-running and maintenance-free
• Standard range from stock

iglide® UW160 was developed quite specifically with regard to maximum wear resistance in media-based continuous operation. In such applications, low radial loads and moderate temperatures usually occur. The suitability for contact with drinking water and very good durability complete the profile of properties. 
 

When to use it? When a KTW-compliant material is required When a wear-resistant material is required for continuous use in liquid media

When not to use? When a media resistant plain bearing for recurring media contact and in the meantime for dry operation is required When a media- and temperature resistant universal bearing is required When a standard bearing is required for use in a wet environment

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.
