      Hello all,

      I am currently performing a modal analysis where I need to input the stiffness and damping matrix for SKF 7207 ACCBM angular contact ball bearing. The manufacturer refused to help as the bearing is sourced outside of their distributors.

      I looked into ROMAC Tilting Pad Bearing program, however, I am not a member.

      Any suggestions to calculate the matrix as a function of loading and RPM are much appreciated.

      Thank you!

      A tilt pad bearing isn't a type of roller bearing so wouldn't have been of much use anyway. Information on roller bearings like the attached paper is available on the internet.
