iglide® FPF, sleeve bearing, mm

iglide® FPF | PTFE-free version of iglide® F

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.

This new iglide® material is not only PTFE-free, but it is also conductive, making it particularly suitable for applications with ESD requirements. It has high compressive strength, good temperature resistance, and good resistance to chemicals. This material is also extremely pressure-resistant; at room temperature, these bearings could be statically loaded up to 15,229 psi.

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.
