Progressive rubber manufacturers throughout North America rely on PRG for a complete range of roll refinishing, grinding, repairing and refurbishment services that meet or exceed specification. We help them maintain product quality and consistency, keep machinery running at top condition for longer periods of time, reduce waste and conserve energy and resources.
PRG’s off-machine roll grinding is the key. For all aspects of the rubber industry, off-machine roll grinding is better than in-place roll grinding. In-place (block) grinding is done in bearings on the machine, which does not produce rolls that meet the original specifications. If something is off on one side or anywhere on the roll, it can’t possibly attain proper shape, roundness and TIR.
Our superior off-machine roll grinding results in rolls that meet or exceed OEM specifications — and deliver significant efficiencies and savings:
Round rolls do more than provide a consistent product. They reduce the wear on machines — wear that creates unnecessary chatter, vibration and more. Working with PRG assures that all aspects of your assembly are properly maintained. All work is performed at our facilities, guaranteeing the grind is done right the first time.
Our services include:
PRG grinding is a proven process guided by computer data. Bearings and housings are removed to guarantee a perfectly round roll in a temperature-controlled facility. In addition, all rolls are measured using a 24-point SpecCheck™. PRG never blindly assumes bearings are working properly and that the journals are without issues such as chatter or lack of roundness.
Manufacture large-scale equipment? It’s not a problem for PRG. Our physical capabilities are among the best in the nation.
