Shaft Repairs & Journal Repairs
The careful selection of materials and surface finish gives maximum life to the components while enhancing the life of the packing materials. Because wear of packing journals is reduced to such low levels, the efficiency of the equipment is enhanced significantly and reliability extends to 3 or 4 times the unprotected life of the unit. Corrosion resistance is also extreme with elevated operating temperatures presenting no issues.
Shafts are repaired with cold-spray processes, which result in absolutely no distortion or substrate metallographic change. This results in assurance that the performance of your shaft will not decline over time. As all work is done in-house, the quality and quick turn around of your critical components is assured.
