iglide® E7 polymer flange bearing, metric

iglide® E7 | Excellent coefficient of friction and wear with low to medium loads

PFAS-tested: All iglide materials labeled as "PFAS-tested" were tested for 96 PFAS substances considered critical for the environment and health. This category excludes substances from the group of fluoropolymers.

For the first time, the material E7, well-known from drylin® linear technology, is also available as a plain bearing with a wide range of dimensions. Bearings made of the new material offer excellent coefficient of friction and wear with low to medium loads. It is also available as a bar stock material. iglide® E7 is especially suitable for steel and stainless steel shafts. This material dampens vibrations very effectively and is especially abrasion-resistant. The low coefficient of friction of iglide® E7 ensures smooth movements, reduces the required drive force, and has the potential for additional cost savings.
 
Application areas:
packaging machines, textile machines, furniture design

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.
