iglide® Q290 polymer sleeve bearing, metric

iglidur® Q290 | for medium to heavy duty, especially on soft shafts
PTFE-free: All iglide materials labeled as "PFAS-free" were tested for 96 PFAS substances considered critical for the environment and health. 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. galvanized). The wear on the shafts is minimal.
 
Typical application areas
Agriculture
Construction machinery
 

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

When not to use it? When permanently high static loads greater than 55 MPa occur. If an extremely wear-resistant bearing is needed on "soft" shafts for minor loads. When temperatures are continuously higher than +140 °C.

 
Tolerances and measurement system
The installation dimensions and tolerances of iglidur® plain bearings are a function of the material and wall thicknesses. For each material, the moisture absorption and the thermal expansion are decisive factors. Plain bearings with low moisture absorption can be designed with a minimal bearing clearance. The rule for wall thickness: the thicker the wall of the bearings, the larger the clearances must be.
 
Assembly
iglidur® plain bearings are press-fit bearings. The inner diameter adjusts only after press-fitting in the correctly toleranced housing. The press-fit excess dimension can be up to 2% of the inner diameter. This ensures the secure press-fitting of the bearing. Axial or radial movement in the housing are prevented this way.
