Horizontal Bearings
SC-Type
The pedestal bearings in the SC range are optimized for stationary use as radial bearings in land applications and can also absorb moderate axial loads. They are primarily used in electrical machines. RENK pedestal bearings in the SC range are optimized for stationary use as radial bearings in land applications and can also absorb moderate axial loads. They are primarily used in electrical machines. The versions can be assembled from a modular system depending on the needs of the respective situation. The SC range of bearings was constructed in such as way that it can also be used together with the familiar E bearing range. The shaft heights and the drilling pattern of the foot mount, for example, match those of the E bearings to a large extent.
Frictional heat is dissipated by radiation and convection alone in many cases. Two lubricant coolers made of seawater resistant material can also be used in the housing, and integrated baffles boost the cooling performance.
WG-Type
The rolling mill bearings in the WG range are designed for extreme axial strain. They were developed primarily for the mounting of rolling mill drive units and large electrical machines in which high axial loads occur at low speeds and a high level of protection against damage must be ensured at extreme loads. RENK rolling mill bearings in the WG range are designed for extreme axial strain. They were developed primarily for the mounting of rolling mill drive units and large electrical machines in which high axial loads occur at low speeds and a high level of protection against damage must be ensured at extreme loads.
This range incorporates the experience we have gained in numerous ranges of RENK bearings. Bearing shells from the SC range come into play here, for example, as well as seals from the E range of bearings and RENK RD slide shoes from the axial bearing area. Using these components therefore offers the advantage of simplified spare parts stocking. In many cases, fixed and floating bearings with the same radial parts and seals can be fitted. Meanwhile, the wear parts are stocked components to a large extent and can be delivered on short notice.
WG bearings have a welded housing, and its strength makes it suitable for withstanding maximum axial shock loads. WG bearings are therefore especially suitable for use as thrust bearings where expensive system components need to be protected against axial forces in the event of an accident. This compact construction and the optimized arrangement of the bearing elements have resulted in a cost-effective welded solution.
HG type
The pedestal bearings in the HG range are self-lubricating slide bearings for high levels of radial and axial stress and were developed primarily for the mounting of hydro generators and electrical machines in stationary applications on land. RENK pedestal bearings in the HG range are self-lubricating slide bearings for high radial and axial load in conjunction with high speeds in a single direction of rotation, independent of the load direction. They were developed primarily for the mounting of hydro generators and electrical machines in stationary applications on land. The key features of the HG bearings are the tiltable, round RENK RD slide shoes. These are supported via cup springs, thereby ensuring a uniform distribution of axial loads.
Marine Bearings
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. 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.
D-Type Thrust bearings
RENK thrust bearings in the D range are suitable for absorbing high axial and radial forces, include shock type forces, regardless of the rotation and load direction. RENK thrust bearings in the D range are suitable for absorbing high axial and radial forces, include shock type forces, regardless of the rotation and load direction. The key feature of the bearings in the D range are the RENK RS / RD slide shoes with a round running surface, which have a proven track record in many bearings in other ranges as well. The bearings of the D type can be operated with natural cooling, water cooling, or external lubrication. The housings are designed as pedestal bearings, as saddle bearings with a lubricant sump, or as saddle bearings without a lubricant sump. 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.
AXILUS® LA Type - Thrust bearings
RENK thrust bearings in the AXILUS® LA range are designed to absorb high axial forces and are used in shipbuilding to absorb the thrust of the propeller as well as in general mechanical engineering applications or in the field of electrical engineering to absorb large axial forces in horizontal machine shafts.RENK thrust bearings in the AXILUS® LA range are designed to absorb high axial forces and are used in shipbuilding to absorb the thrust of the propeller as well as in general mechanical engineering applications or in the field of electrical engineering to absorb large axial forces in horizontal machine shafts. The bearings also absorb radial loads that occur. In addition to the standard bearings in the various AXILUS® LA series, we offer custom solutions for special customer-specific requirements under the AXILUS® LAZ designation. Thrust measuring device, special strength requirements, overload protection, displacement compensation, noise reduction in the shaft train, and a nonmagnetic version are just a few examples of what we can do. As a systems supplier, we offer options such as shaft brakes, turn drives, or lubrication systems in combination with our thrust bearings. We identify package solutions that are specially adapted to the customer’s requirements.
