1 ea. FAG Spherical Roller Bearing 22230-EASK.M 150mm x 270mm x 73mm Made in USA
Part Identification and Nomenclature
The 22230-EASK.M.C3 is a double-row spherical roller bearing in the 22200 series, denoting a 150 mm bore. Its code breaks down as:
E – high-capacity internal design
A – pressed-steel cage
S (often shown as XL) – X-life optimized internal geometry for extended service life
K – 1:12 tapered bore
.M – machined-brass cage
.C3 – radial internal clearance greater than normal sp-spareparts.com NTN Americas
Design & Construction
This bearing features two rows of barrel-shaped rollers running on a concave spherical outer raceway, allowing self-alignment up to several degrees to compensate for shaft deflections. The solid inner ring and open design facilitate lubrication, enabling high radial load capacity and the ability to carry axial forces in both directions. abf.store en.tradebearings.com Technical Specifications
