Selection and Installation

Assess axial load, radial load and overturning moment together with speed, duty cycle and mounting stiffness. Confirm the bolt circles, hole sizes, material grade, seal configuration and lubrication requirements before ordering. Use flat, adequately stiff mounting surfaces and the specified bolt-tightening procedure. Match the gear module or diametral pitch, tooth count and gear face width to the pinion, and check the permissible tooth load.
