FAQ What is the primary function of an FRM spacer ring?An FRM axial spacer ring is used to create a precise gap or to apply a specific preload on a bearing arrangement. It works with a precision locknut to clamp the inner ring of a bearing, ensuring high accuracy and rigidity in the assembly. Are the FRM 140/12.5 rings hardened and ground?Yes, FAG spacer rings are manufactured from high-quality steel and are typically hardened and precision-ground on their faces and cylindrical surfaces to ensure extremely tight tolerances for parallelism and width. Can this spacer ring be used with any type of bearing?While versatile, FRM spacer rings are primarily designed for use with precision bearings like cylindrical roller bearings, tapered roller bearings, and angular contact ball bearings where precise axial positioning is critical for performance. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
