Applies to all Sundyne integrally geared drive pumps – LMV/BMP-3XX models

Journal bearings are a vital component of all Sundyne pumps and compressors with high radial and/or thrust loads. They provide a sheared layer that allows the surface of the shafts to slide relative to the stationary part of the machine – essentially, they protect the shafts by separating them from the gearbox. In depth technical knowledge of each Sundyne unit and advanced manufacturing capabilities are required to properly size the Sundyne journal bearing to the precise measurements necessary for optimal operation. Failing to meet these specifications puts the Sundyne pump or compressor at risk of premature failure.
