Installation techniques for reaction-sintered silicon carbide products
- Dec 15, 2018 -

There is a great relationship between the installation and use of the reaction-sintered silicon carbide products. In order to exert the good performance of the reaction-sintered silicon carbide products, we must perform accurate installation during the installation process. First, clean any burrs or rough spots on the shaft to ensure that the bushings are not installed in keyways, cross holes, splines, or the like.


Measure the unworn portion of the shaft, the diameter at which the bushing is to be installed, measure at three locations, and take the arithmetic average to ensure that the shaft is within the recommended specifications. Measure the exact point or mark it directly on the surface. The bushing must be placed in the worn area, not just at the bottom or left flush with the shaft end.


If the flange needs to be removed after installation, the flange outer diameter should be cut to the arc at some point before installation. The flange end of the bushing is first mounted on the shaft, and then the installation tool is placed on the bushing. Tap the mounting tool until the bushing covers the wear shaft surface. If the installation tool is too short, use a burr-free tube or a square-end tube to ensure that the inside diameter of the tube is the same as the inside diameter of the installation tool.


The wear sleeve should always be installed such that the edge of the bushing is entirely attached to the shaft. Remove the flange, taking care not to pull the end of the bushing from the shaft as well, leaving a jagged edge; after installing the bushing, check again for any burrs that can damage the seal. Lubricate the bushing with system media before installing the seal, then install the seal.
