4. Mechanical Equipment Repairs Shaft Repairs – Machined Rebuilding product is applied while the part is in the chuck. After it sets up (about 2 hours) it is machined back to size.
5. Mechanical Equipment Repairs Shaft Repairs – Using the Former ( split sleeve) Technique Shaft is damaged, disassembly is difficult or impractical. Repair in place is attractive.Remove old bearing. Prep the shaft with grinders. Machine a split sleeve. The I/D of the sleeve is to be the same as the O/D of the shaft. Weep holes are drilled in the sleeve . Release agent is applied to sleeve. Rebuilding material is applied to both shaft and sleeve and sleeve is clamped in place. Once the material has cured ( 2 to 4 hours), the sleeve is removed. Parting lines and nubs from the weep holes are cleaned up with emery cloth and the shaft is ready for reassembly.
7. Mechanical Equipment Repairs Splined shafts This is a common and valuable repair. Release agent is used on the female side. Similar to the key-way repair, this will often out last a replacement part.

9. Mechanical Equipment Repairs Hydraulic Rams The hardest thing about a hydraulic ram repair is deciding to grind on the shiny ram. We have to make the gouge deeper and wider in order to fix it. This is a very durable repair.
10. Mechanical Equipment Repairs Bearing Housings Bearing housings are damaged when a bearing fails and rotates in the housing The repair is simply a matter of replacing the lost material and machining back to proper size. This repair can also be made by forming the fit with a dummy bearing and release agent.

20. Concrete Protection Chemical Containment We offer a broad range of specialty coating for primary and secondary chemical containment of both acids and caustic in high concentrations. Almost any industrial chemical can be addressed by our range of product.
21. Seamless Floor Systems We offer a broad range of seamless floor systems. Water based, solvent free, 100% Solids, epoxy and polyurethane based systems are all available. We will work with you to select the right system for your specific application. These systems are safe and easy to use. They can be applied by in house crews or by our approved contractors. We provide on-site training and technical support for everything we sell.
22. Non-Skid Positive Grip Systems By incorporating an appropriate aggregate into our resin systems, we can create positive grip systems for a variety of purposes. The rolls above are coated with Metal-Tech FG and then aluminium oxide grit is applied to provide positive grip on these break testing rolls. The same system is applied to lumber mill rolls for more efficient movement of lumber thru the mill. Non-skid aggregate can be added to any one of our floor systems to produce greater traction where it is needed.
