Axis, install the SKF bearings housing or bearing and bearing device in other parts, there must be sufficient rigidity. Because these parts deformation will block the rolling element rolling bearing destruction in advance. The housing and the bearing housing should have a sufficient thickness siding on the cantilever bearing housing should be as short as possible, and the supporting portion is reinforced with stiffener rigidity. If the surgery is made of light alloy or non-metallic, steel or cast iron cylinder liner.
Two support a shaft bore must remain concentric as possible, so as not to have too much skew between the inner and outer rings. The best use of the overall structure of the shell, and once installed SKF bearing two holes bored. Such as a shaft with different size bearings, the bearing hole on the shell should be a boring, then can use the liner to install a smaller size bearings. When two bearing hole is divided in two housing should be two housings together boring.
