iglidur® J4, sleeve bearing, mm - J4SM

iglidur® J4 | Low-cost material
 

• Lubrication and maintenance-free
• Low-cost material for high-volume production
• Low coefficient of friction
• Good media-resistance
• Low humidity absorption

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

Tolerances and measuring system
The installation dimensions and tolerances of the iglidur® bearings depend on the material and wall thickness. Moisture absorption and thermal expansion are decisive for the material. Plain bearings with low moisture absorption can be designed with a minimal amount of bearing clearance. The following applies to the wall thickness: The thicker the bearings, the greater the bearing clearance must be.
Test procedure

Installation
iglidur® bearings are press-fit bearings. The inner diameter is only adjusted to the appropriate tolerance after pressing into the housing bore. The press-fit interference can be up to 2% of the inside diameter. This ensures the secure press-fitting of the bearing. Axial or radial displacements in the housing are thus reliably avoided.
