Industrial Gearbox Warranty Services


With our expert staff, we repair and service industrial gearboxes and speed reducers. We inspect and assess the entire unit for issues such as cracks and chips in gear shafts and bearings. When we've finished, we'll notify you of all repairs needed.


We repair industrial gearboxes to their highest standards and will not compromise on quality, service, or value. Our technicians can do repairs onsite, reducing downtime and lowering costs or you can ship your gearbox or speed reducer to any of our United States facilities. All work is completed to the manufacturer's original specification, using genuine spare parts by default but reverse engineering replacement components when needed. We thoroughly inspect and test everything before we return it back to you.


Your gearmotor or reducer will be repaired to the original factory like-new specifications with warranty using Sumitomo manufactured parts. Our industrial gearbox repair team is the industry’s most versed gearbox problem solvers with centuries worth of experience. We provide both standard and custom services, for maximum industrial gearbox life. Trust Sumitomo with your small, medium, and industrial gearbox repair services.
