One of the significant problems associated with greased metal bearings in sedimentation tanks is their susceptibility to damage from sticks, rags, and other types of debris that can move through the tank. Anything obstructing the grease from reaching the bearings can result in the bearings getting galled or seized. Dewatering a tank to repair bearings can be time-consuming and extremely costly. Fortunately, a great solution to this problem is to replace traditional greased bearings with Thordon SXL grease-free bearings. After undergoing testing for 18 months in a sedimentation tank without any grease lines, Thordon SXL bearings exhibited no signs of wear or corrosion, and the steel shafts showed only minimal wear. Although they may cost a bit more to install initially, Thordon SXL bearings require minimal maintenance and save you from costly downtime and continuous repair costs.
Thordon SXL is a crosslinked elastomeric polymer alloy bearing. It’s made from thermosetting resin and three-dimensional, crosslinked condensation polymers.
The following properties allow Thordon Bearings to work under extreme conditions.
