Assess radial load, axial load and overturning moment together with speed, duty cycle and mounting stiffness. Confirm bolt circles, hole sizes, seal configuration, material grade and lubrication requirements before ordering. Mount on flat, adequately stiff surfaces and follow the specified bolt-tightening procedure. Obtain a confirmed installation drawing for the mounting dimensions before manufacture or installation.
