TRI Transmission and Bearing repairs and refurbishes all types of babbitt bearings. As a bearing engineering, design, and manufacture source we have expertise in all aspects of bearing repair including bearing failure analysis. We repair babbitt bearings under all conditions. TRI is very responsive when it come to refurbishing babbitt bearings. Our staff are highly trained and skilled experts in bearing repair and can support any outage on a 24 hour a day 7 days a week schedule.

TRI understands your need to get your equipment back online as quickly as possible, whether you need our services for a scheduled preventive maintenance outage or an emergency outage, TRI will complete your babbitt bearing repair on schedule and right in the industry. TRI can repair bearings up to 84" OD.

Do more then repair the problem. Fix the problem.

TRI uses computer simulations to evaluate bearings . We use a vertically integrated process that goes from analysis and design to manufacturing and installation has resulted in an enviable experience record for both fixed bore bearings and tilt pad bearings. In the design process, TRI uses its proprietary computer programs to adjust the design in order to optimize oil film thicknesses, film pressures, bearing metal temperatures, and power losses, and at the same time, to suppress sub-synchronous rotor vibrations over the load range of the bearing application. For bearings from other manufacturers that have been damaged in service and are being repaired at TRI, we often propose design adjustments based on the results of TRI’s computer simulations.
