After the untimely passing of the ROC Carbon patriarch, Mrs. Dody Ricks had two choices: close up shop or pick themselves up and soldier on. Like any great company, the team rallied behind their leader.

While she was utterly devastated, Dody knew that letting her husband’s 20-year project-in-the-making fall to the wayside was not an option; she also knew that she needed someone with the same drive and vision as her husband. With such an endeavor before her, Mrs. Ricks did what she had always done before – she put her destiny in the hands of her faith. She knew that she needed someone who was trustworthy to take the reins. As fortune would have it, a friend of a friend was looking for a small family-owned company with room to grow. After countless meetings, discussions, and reflection, Dody brought Alfred ‘Al’ Turala on board.

This due diligence would shape the future of ROC Carbon for decades to come. The first thing Al set out to do was to oversee operations and establish a path forward for the company, which he did from 1978 until 1985. During that near-decade, Al helped ROC Carbon grow to new heights. After running the company for so long, he knew two things to be true: that someone would have to eventually step into the proverbial “captain’s chair” and that it had to be led by a member of the Ricks family. Al knew who that someone should be – Pam, the daughter of Mr. and Mrs. Ricks. He approached her one day and asked if she was ready to assume the leadership role, which she initially declined. Pam loved being in HR. She loved working with the people in the company. Al finally made her an offer – Pam could learn first-hand from Al, who would teach her all he knew about running a business. Pam was now at the crossroads of her career.

Metal-Backed (MB) Components are graphite or carbon graphite parts with a metal sleeve on the outer diameter. These parts are available as either a bushing or a seal. Manufacturing these parts involves a proprietary method to achieve proper circularity and accurate sizing. ROC also ensures the correct interference fit between the carbon and metal to meet the requirements of your operating conditions.


Metal Backed Type Bushings

Bushings made with a metal backed components sleeve have several advantages over our standard carbon bushings. First, the metal sleeve can offer protection to the housing if there is an upset event that damages the carbon bushing. The sleeve becomes an easily replaceable sacrificial element, allowing the bushing to be easily replaced without performing repair work on the housing.

Metal-Backed Bushing

Next, installing any carbon bushing requires an interference fit between the housing and the carbon. A skin cut on the bearing bore is usually necessary to ensure it is perfectly round. This may be very difficult to machine, due to the housing size or the bushing location in the equipment. Our MB type bushing is more tolerant to a slightly out of round bore than the standard carbon bushing, and the press-fit of the sleeve into the housing is less than the standard carbon bushing. This allows the bushing to be installed without additional machining and without the need to heat the housing to install the bushing.


Metal Backed Type Seals

Metal-Backed Sealing

ROC Carbon Metal-Backed Components type seals are manufactured to precise tolerances for high-speed compressor and gas turbine applications. Adding a metal sleeve to the OD of the carbon seal provides support to stiffen and strengthen the seal. Also, because the sleeve is placed on the seal with an interference fit, the clearance between the shaft and ID of the seal is very close to constant as the operating temperature increases.


Because of the tight manufacturing tolerances, larger seals are fitted with an ID plug to help maintain the roundness of the seal during shipping and storage. This plug is removed prior to installation.

Lapping is also available for the sealing faces after the parts are finished machined.

ROC Carbon precision manufactures our MB-type components to provide high performance for bushing and sealing applications.
