Good resistance to oil. Standard elastomer. (Also applies to SXB Cushions.)
  • Interchangeable with all hub sizes standard for the L-Line and AL-Line products
  • Available in a variety of different finished bore and keyway combinations
  • Finished bores passivated for additional rust protection
  • Lovejoy does not recommend reboring AL hubs.
