PRODUCT OVERVIEW
2215AK — Self-Aligning Ball Bearings
Two rows of balls run in a common spherical outer raceway. The design accommodates shaft deflection and alignment differences while supporting predominantly radial loads.
Permissible misalignment depends on the series, seals and bearing arrangement; these bearings are not intended for pure axial loads.
Typical application areas: Textile machinery, Woodworking equipment, Fans, Shaft supports. Suitability is reviewed against the specific operating conditions and bearing arrangement.
