IKO CRBFV3515ATUUT1 Cross Roller Bearing
CRBFV3515ATUUT1 is a high‑rigidity, mounting‑holed crossed roller bearing from IKO’s CRBFV series. It features cylindrical rollers alternately crossed at 90° in precision V‑grooves, guided by a precision separator. This design enables the bearing to support radial, axial, and moment loads simultaneously in a compact profile.
