Selection and Installation

Check axial load, radial load and overturning moment together, including duty cycle and mounting stiffness. Match the bolt circles, hole sizes and ring heights to the mating structure. Confirm seal configuration, material grade and lubrication requirements before ordering. Install on flat, adequately stiff mounting surfaces. Follow the specified bolt tightening procedure and lubrication schedule. Do not use the limiting moment rating alone as a complete application approval.
