iglide® J4 polymer sleeve bearing, metric

iglide® J4 | Low-cost material

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.

• Dry-running and maintenance-free
• Cost-effective material for mass production
• Low coefficients of friction
• Good liquid media resistance
• Very little humidity absorption

iglide® J4 is the low-cost material for long service life with low to medium loads.
 
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.
