High-Speed Gearbox SN2285 for Aerospace Product Testing

Cotta recently designed and built this new High-Speed Gearbox Model SN2285 for testing use on aerospace products by a customer in the Indianapolis, IN area. Our Model SN2285 is a foot-mounted, single increasing stage, single output, high-speed gearbox that is designed for test stand use.

Remote Monitoring Technology

Cotta offers industry-leading Remote Monitoring capabilities for many of our gearboxes, allowing the user to view real-time performance of specific gearbox functions. A variety of parameters can be viewed on a customized dashboard accessed via webpage. Critical decisions, such as scheduling routine maintenance, can be made without onsite physical inspection of our gearbox – saving both time and money. Remote Monitoring is ideal on equipment operating at remote locations for applications like mining, oil & gas, wastewater, environmental utility, and many others. Let’s talk about how this capability may be able to fit your specific needs! Visit our Remote Monitoring Webpage for more information.

Speed Reducers over 30 Years on USCGC Alex Haley

Cotta recently received four speed reducing gearboxes for repair from Lake Union Drydock Company for the USCGC Alex Haley. These gearboxes have been in continuous service for over 30 years and will be rebuilt and returned for installation on the USCGC Alex Haley (WMEC 39) that is currently used for Fisheries Law Enforcement & Search and Rescue missions. Our team was able to efficiently turn this repair around in order to get the vessel back in service for the Coast Guard.

The gearbox repair or refurbish process here at Cotta can take one third the time you would typically expect from specifying, ordering and building an all-new gearbox – saving you downtime and overall cost!
