Engine bearing ‒ SM type

RENK flange-mounted bearings in the SM series were specially developed for use as an engine bearing in naval applications. Designed for steeply inclined positions, the construction enables self-lubricating and therefore extremely quiet operation. Seawater resistant finned tube coolers integrated into the oil sump ensure optimal cooling performance.
Because the bearing shell is installed in the housing with a ball joint, the effort of aligning the bearing is reduced to a minimum and edge strain is prevented. Depending on the requirements, either hydrodynamic thrust surfaces or the tried-and-tested RENK RD slide shoes are integrated directly into the supporting body of the bearing shell to enable use as a fixed bearing.
A bearing housing made of gray cast iron is used in the standard version. When it comes to special applications, we offer decades of experience in developing customer-specific solutions with bearing housings in welded designs.
