FAQ

What does the ‘PPA’ suffix mean for the SKF KRE 22 PPA?
The ‘PPA’ designation indicates that the bearing is equipped with an axial sliding ring made of polyamide 66 on both sides. This provides effective sealing against contaminants and moisture, while also retaining grease, which is crucial for extending the bearing’s service life in demanding industrial environments.

Is the outer ring of the KRE 22 PPA cylindrical or crowned?
The SKF KRE 22 PPA features a crowned outer ring running surface. This profile is beneficial as it helps to accommodate slight misalignments and reduce edge stresses, preventing premature wear and tear when running on a flat track.

What is the recommended tightening torque for the M10x1.25 nut on this track roller?
While the specific tightening torque depends on the application’s requirements, a typical recommended torque should be carefully applied to ensure secure mounting without deforming the stud or bearing components. Always consult the machine’s maintenance manual or SKF documentation for precise values for your specific application.
