MORGOIL Test Stand

Designed for the development of the KLX bearing

Allows testing of a full size 28”-76 KLX bearing.

Cantilever design so the bearing can be an exact duplicate of what would be installed in a mill.

Full size HAGC cylinder for loading (900 tons)Speed up to 1000 RPM120 channels of instrumentation for pressure, temperature, strain, flow, torque, and RPM Oil film measurement (+/-2.4 microns)Highly controllable lubrication system (90F to 120F temperature and 0 to 25 gpm flowHydrostatic assist up to 30,000 psi with variable flow

R History – KL “Keyless Bearing”

KLX Sleeve Technology

The thickness has been reduced and the internal flange removed

This sleeve has a more consistent cross section, making the loading on the sleeve more uniform

New design allows the sleeve to better conform to the pressure field produced by the oil film

Distributes the load over a larger areaThe result is a higher average bearing pressure: 4000 psi (27.6 MPa) under normal operational conditions and 4351 psi (30 MPa) under optimum conditionsKL is 3556 (24.5 MPa)
