Orkot® bearings wear well at low velocities


Proven in extensive test program

An extensive test program was conducted to prove Orkot® TXMM bearing material performance at low velocities. Bearings were tested to extremes velocities down to five meters/ 16 feet per minute at pressures up to six bar/ 87 psi and water flows down to two liters/ four pints per minute. The seawater contained Silica flour at 250 parts per million and the 200 mm/ eight inch bearing operated on an LG4 Bronze sleeve for 2,000 hours. The resulting overall wear of the bearing was just 0.027 mm/ 0.001 inch per 1,000 hours and shaft wear was minimal with an improved shaft finish. The tests were repeated successfully with Inconel and Nickel Chrome Boron coated shafts.
