Vertical Bearings
EV-Type
RENK vertical bearing inserts in the EV range were developed especially for use in high-speed machines with vertical designs, such as pumps, fans, turbines, or electrical machines.. RENK vertical bearing inserts in the EV range were developed especially for use in high-speed machines with vertical designs, such as pumps, fans, turbines, or electrical machines. EVE bearings are available as combined thrust and guide bearings with a radial and axial component, while EVF bearings are provided as radial guide bearings only. The key features of the EV bearing inserts are the tiltable, round RENK RD slide shoes. These are supported via cup springs, thereby ensuring a uniform axial distribution of loads. The radial component of an EV bearing consists of individually adjustable radial tilting pads. EV bearing inserts can also be provided with a lubricant container in the appropriate size upon request if the machine housing isn’t designed to serve as a lubricant container or a lubricant container that is adapted to the machine and manufactured in-house is preferred. Depending on the operating conditions, the power loss of the bearing can be dissipated through the natural cooling of the lubricant container, through additional cooling via a finned tube cooler built into the lubricant container, or through external cooling of the circulating lubricant.
V-Type
RENK vertical bearings in the V range are mainly used in low- to medium-speed machines with vertical designs, such as pumps, fans, turbines, or electrical machines. RENK vertical bearings in the V range are mainly used in low- to medium-speed machines with vertical designs, such as pumps, fans, turbines, or electrical machines. VT bearings are available as combined thrust and guide bearings with a radial and axial component, while VG bearings are provided as radial guide bearings only. The key features of the VT bearings are the tiltable, round RENK RD slide shoes. These are supported via cup springs, thereby ensuring a uniform axial distribution of loads. The radial component serves as a guide bearing. If necessary, a four-lobe shell can be used instead of the cylindrical shell. This shell has a stabilizing effect on the shaft, which is subjected to a load radial load or none at all. Depending on the respective operating conditions, the VT / VG bearings are operated with natural cooling, external lubrication, or integrated water coolers. Using a fan expands the range in which natural cooling can be used to include higher speeds. If there is an external lubricant system, the housing is equipped with an overflow chamber that always contains enough lubricant for short-term emergency operation until the machine is shut down.
