Rotary positioning systems, compact turntables and automation machinery.
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.
