iglide® Q290 polymer flange bearing, metric

iglide® Q290 | for moderate to high loads, especially on soft shafts

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.

• Long life especially on soft shafts
• Continuous use up to +284 °F
• Resistant to edge loads
• Dry-running and maintenance-free

iglide® Q290 shows outstanding service life in robust swivel applications, as they are frequently found in some agricultural machinery, especially on "soft" shafts (e.g. galvanised). The wear on the shafts is minimal.

When to use it? If a long-lasting bearing is needed for rugged operating conditions (agricultural equipment, construction machinery, etc.) with moderate to high dynamic loads on "soft" shafts.

When not to use? When permanently high static loads higher than 7977 psi occur. If an extremely wear-resistant bearing is needed on "soft" shafts for minor loads. When temperatures are continuously higher than +284 °F.

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.
