CG-1 Hydrodynamic Bearings

CG1 Hydrodynamic bearing

A direct replacement for the Dodge RTL Sleevoilâ„¢ that eliminates the need for water cooling. The CG-1 is a cooling free, housed, fully split, self-aligning, hydrodynamic bearing with the same performance as a water cooled Dodge RTL Sleevoilâ„¢ bearing.

A proven record of conversion

CG-1 bearings are in many critical applications with manufacturers and power plants in the United States. Our users save thousands of dollars per year, per bearing, in operating cost, versus traditional water-cooled bearings. On average each CG-1 bearing installed saves 2.9 million gallons of pumped water per year, eliminating a large portion of the plant water or air distribution system including water or airlines, insulation, pumps, treatment chemicals, hot water retention capacity, and required maintenance.

CG-1 Construction

Housings are heavy duty cast iron with an extra thick solid base, making a ridged vibration dampening assembly. Each is equipped with highly configurable labyrinth seals with built-in optional air sealing and felt packing. The housing also can use third party bearing isolators, connection to a circulated oil system, and installation of conventional thermal and vibration sensors. The bearing is self-aligning with a full spherical seat, uses a centrally located thrust bearing for non-expansion service, and can operate as a fully self-contained unit using oil rings.

Made in America
