EV type – vertical bearing insert
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.
Features
- Bearing design tailored especially to vertical applications
- Spring and shock-absorbing characteristics can be adapted by adjusting the radial tilting pad.
- Noise and vibrations during operation are generally low
- Efficient condition monitoring thanks to easy evaluation of the bearing temperature
- Available as a package with numerous combination options
