Carbon Ring Shaft Seals, Graphite Bushings, and More
Expect Only High-Performance
from ROC Carbon
for Rotating Equipment
ROC Carbon can help you get maximum service life and performance out of your rotating equipment. We provide premium-quality, after-market carbon ring shaft seals, graphite bushings, and other parts made to exacting standards found in OEM parts. We also make economical, custom parts for machines that have been modified. Our high-performance replacement parts can help maximize the productivity of older, out-of-warranty machines to keep them in service longer. No matter how old your machine is, we can make and stock parts for it.
If you need to improve operating life or modify design parameters to increase efficiency and to meet environmental standards, we can help. We have seen and solved countless seal and bearing problems involving a wide variety of rotating equipment in all kinds of service and operating environments. Many times these problems are solved with our upgraded parts that are superior to standard OEM replacement parts.
In general, ROC Carbon carbon/ graphite seals and bearings are used where extreme operating temperatures and/or corrosive fluids would cause conventional lubricants to decompose, where lubricants would contaminate process fluids, and where equipment design makes conventional lubricating systems too expensive to install and maintain. Non-lubricating applications for which ROC Carbon supplies carbon/graphite grades include electrodes and brazing boats, jigs, and fixtures.
ROC Carbon’s high-performance designs often involve modified dimensions or part geometry, and we can furnish entirely new designs to solve difficult problems. In many instances, improved part performance can be achieved simply by substituting a proprietary ROC Carbon material grade for the originally specified material. We have a line of specialty carbon/graphite grades matched to specific seal and bearing requirements.
Often, by improving material characteristics and properties, we are able to solve problems to meet your specific needs, whether those needs call for carbon ring shaft seals, graphite bushings, or anything in between. For most seal and bearing applications, the carbon is impregnated with resin, metals, inorganic salt, or other materials to provide the desired mechanical, corrosion-resistant, temperature resistant, or wear-resistant properties.
