Dodge® Sleevoil® RTL series hydrodynamic bearings provide exceptionally strong performance in high heat applications. The liner design offers excellent radial and thrust load capacities. Coolant chambers directly in the liner provide especially effective heat dissipation and cool both the thrust plates and radial load sections as close to the heat source as possible. The coolant chambers are of sufficient size to allow the use of water, oil or air as the internal coolant. All components are fully split. Housings are pre-machined for thermocouples, circulating oil, heaters and thermostats. The Dodge® RTL design accommodates shaft diameters from 3-7/16 in to 12 in. Dodge® RTL series is used on motors, generators, fans, test stands, dynamometers, pumps, compressors and other turbomachinery.
