Emerson Bearing Boston ceramic hybrid bearing line expansion

Emerson Bearing Boston, a bearing company catering to Original Equipment Manufacturers (OEM) and Maintenance, Repair and Operations (MRO) markets around the world, had expanded its ceramic hybrid bearing line.

Emerson Bearing offers ceramic hybrid bearings which are suitable for applications that demand performance, reliability, and increased longevity — particularly in the machine tool, aerospace, and chemical industries.

Ceramic bearings are comprised of ceramic rolling elements enclosed in a ferrous (typically steel) inner and outer race. Since these bearings are constructed from many materials, they often operate in hybrid capacities. The benefits of ceramic bearings over conventional steel bearings include: reduced weight; increased durability; enhanced acceleration capability; and reduced friction. Ceramic bearings also offer the benefit of not allowing electrical currents to run through the bearing, which allows for prolonged use.

Emerson Bearing’s expanded ceramic hybrid bearing line includes top brands Nachi, FAG, KOYO and NSK.

“As studies show, ceramic bearings can last anywhere between five and 20 times longer,” explained Steve Katz, president. “Not only that, but their running speeds can be up to 50% higher. Ceramic bearings’ resistance to corrosion and degradation means they can operate in harsh environments, and their electrical insulation properties eliminate the risk of electrical erosion and pitting of the rolling elements.”

From Satellites to High-Speed Machining & Mixing Applications

Lightweight and vacuum-compatible, ceramic bearings are suitable for satellites and spacecraft, which require optimal weight capacities to enhance flight dynamics and acceleration. They can operate without lubricants such as heavy greases and oils, which tend to attract contaminants that interfere with sensitive electrical components.

Ceramic bearings are corrosion resistant as well as chemically inert and do not react with harsh chemicals or leach particulates into sensitive solutions, which makes them best for chemical and mixing applications. Other applications that benefit from ceramic bearings are precision instruments and high-speed machining.

Katz continued, “Ceramic hybrid bearings offer unmatched performance in a variety of applications, but are especially suited in machine tool, aerospace and chemical applications. Our experts can assist in the selection of the right bearing to ensure superior performance and avoid costly pitfalls and downtime.”
