Made-to-order sealing solution for roller bearings in steel plants

The radial shaft seal Merkel RadiamaticRPM 41 is specifically designed for use in steel plants and can be delivered in any size within 24 hours. A vulcanized-in steel element not only offers a secure, tight fit but also prevents potential damage to the housing as well. Maximum sealing function with minimal friction is ensured by a sealing lip made of pure elastomer.

Simple and fast assembly

The seal can be pressed into the housing seat quickly and without much force. For disassembly, two fingers are generally all you need to pull the sealing ring from the installation space in a single, diagonally-inward movement.
Despite this effortless assembly, the new shaft seal sits firmly in the installation space at up to 0.4 bar of overpressure.
