Bearing units for S-valve in concrete pumps are the most important components in S-valve unit. Thanks to their complex structure and the features of bearing systems a long lifetime of the pumping groups is possible. The bearing housings are assembled in the hopper and due to a system of bearing sleeves, wear bushings, sealings it all composes a complete unit of S-valve bearing.
In concrete pumps we can distinguish:
bearing unit on the drive-shaft side;
bearing unit on the outlet side
The most important case related to the functionality of the bearing units is the working condition of the greasing system (manual or automatic). Penetration of concrete causes a progressive damage and thorough supervision of both bearing units is essential.
Bearing bushings in the bearing units of the S-valve play a key role in the design of this unit. This is because of precise guidance of the S-valve shaft and […]
