- Worn shaft keyways can be repaired using Belzona 1111 (Super Metal). Keyways become worn and oversized due to constant pressure from starting and stopping, causing vibration, misalignment and stress on couplings. Belzona #epoxy composite materials are designed to repair and prevent these common failures to mechanical power transmission equipment. Using a new key as a former, a perfect zero-tolerance fit is created. This simple repair saves time and money, while quickly returning the equipment to operation. In this video, we demonstrate to you how you can rebuild an oversized keyway with Belzona 1111.

Lol fancy JB weld is all
Nice work
Man I need help bad. I got a weeping water leak on a 2 inch mpt threaded black iron pipe. Do you have a solution?
Very sceptical about this. Is the manufacturer willing to give out the material properties?
Hello! you can find product specification sheets on our site: belzona.com or contact our Engineering department at tkl@belzona.com
How long does it need to be set up before the keyway is removed? Also, what kind of liquid is used to clean the scored area prior to application of the mixed 1111?
Thank you for your question! We recommend a full mechanical cure before the equipment is put back to service. Please refer to the Manufacturer's Instruction for Use for specific cure times at certain operating temperatures. www.belzona.com/viewfile.aspx?id=51037 Additionally, Belzona 9111 (Cleaner/Degreaser) was used to clean the repair surface. Please feel free to let us know should you have any other questions or contact your local Belzona representative: www.belzona.com/en/contact.aspx Best regards, Belzona Team

This would not last in an industrial setting
I know it's hard to believe an epoxy solution could be capable of the intense industrial work we set it to however, over seventy years of developing solutions for industry we've proven their capabilities.
If you're still not convinced you can check out this selection of keyway repair case studies we've collected over the last couple of decades. khia.belzona.com/en/search-results.aspx?q=keyway%20repair#gsc.tab=0&gsc.q=keyway%20repair&gsc.page=1

too expensive new crank is cheaper
I dont think sanding that bearing or gear surface is a good idea
