Shaft seals from Mittaletku
The shaft seal is an important part of many machines and devices where there must be a tight connection between the shaft and the bearing. The shaft seal, also called a stefa or radial shaft seal, is designed to prevent the leakage of fluids and other substances from the space between the bearing and the shaft.
Stefs are typically made of a rubber material connected to a metal ring rim. This design provides a strong and durable seal that can withstand high pressures and high rotational speeds. Shaft seals are usually installed inside the bearing housing to seal the space between the shaft and the bearing.
Changing the struts is a common maintenance procedure that can be easily and quickly performed independently. When replacing, it is important to also check other parts of the bearing, such as the surface of the shaft, and replace them if necessary. An incorrectly installed shaft seal can lead to leaks and damage to the bearing.
We have a wide selection of different shaft seals and spacers for different uses. Contact us and tell us about your needs, and we will help you find the best solution for your shaft seals.
