iglide® H4 polymer flange bearing, metric

iglide® H4 | The automotive standard for temperatures up to +392 °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.

• Low coefficients of friction
• High wear resistance
• High temperature resistance –104 °F to +392 °F
• High chemical resistance
• Dry-running and maintenance-free
• Standard range from stock

iglide® H4 bearings stand for high carrying capacity, good abrasion resistance and good temperature resistance, besides the obvious economic factors. temperatures up to +392° F, permitted surface pressure up to 9427 psi, and excellent chemical resistance are only some of the essential attributes. Solid lubricants lower the coefficient of friction and support the wear resistance, which was essentially improved compared to the likewise cost effective iglide® H2 bearings.
 

When to use it? Application with fuels, oils etc. When high wear resistance is required For low coefficients of friction For high temperature resistance from –104 °F to +392 °F For high chemical resistance

When not to use? For underwater use When a cost-effective universal bearing is required When you need a temperature- and media resistant bearing for static applications

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.
