Selection and Installation

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. Check the gear pitch, tooth count, face width and permissible tooth load against the mating pinion.
