The combined wear of thebronze and babbitt gives the remarkableshowing which the Spiral Bearing is oil grooves, cast in the bronze lining,carry the oil from the dope hole to the endsof the bearing and back again, thus insuring perfect lubrication and preventing anywaste of oil. The saving in lubricants is an important feature of the Spiral Bearing.
