Coupling Repair/Refurbishment

No mechanical product can last forever, and couplings are no exception. Why replace a coupling if it can be returned to a serviceable condition for 30% to 90% the cost of buying new? You don’t, but it takes the knowledge and experience of technicians, inspectors, engineers, and the proper facilities to repair a highly engineered product. We do more than just disassembly and re-assembly couplings with new components. We analyze the performance of your coupling and offer recommendations to improve component performance with our understanding of coupling design and your application.

Gearbox Repair/Upgrade


Over time the performance of a gearbox can degrade due to wear of gear teeth, wear of bearing elements, degradation of housing bores, and seal leakage.  Many gearboxes can be repaired at the fraction of the cost of new, even in the event of a catastrophic failure.  It takes the combination of an experienced, knowledgeable group of technicians, inspectors and engineers and a fully capable facility to ensure the proper results.  We don’t stop at simply returning the gearbox to its design parameters.  With our knowledge of gearbox design and working with our customers to understand their applications and needs, we offer options to improve performance with value-added upgrades.
