NTN Spherical roller bearing 23138B--- is a representative NTN spherical roller bearing. This bearing has self-aligning properties, and therefore is suited for use where misalignment between the inner and outer rings occurs from housing installation error or shaft flexure. And these bearings have a large capacity for redial loads, axial loads in either direction, and complex loads.
