A larger centering diameter (130 mm) improves alignment precision and stiffness, reducing run-out and vibration for heavy loads; but it demands matching mounting hardware and precision machining of mating flanges. Using incorrect centering can lead to uneven load distribution and reduce bearing life.

Having that torque at standstill means the motor can hold a load without slipping, but for dynamic motion, you need to ensure rotor inertia is close to external load inertia to avoid overshoot or oscillation. If external inertia is much larger, you’ll have sluggish acceleration and possibly heating.

Heat has to be dissipated primarily through the motor housing; with standstill torque, losses from current (I²R) are high, so ambient cooling, ventilation, or external cooling may be required. Also, insulation class and winding temperature limits must be observed to avoid insulation breakdown.

A shaft seal protects internal components from dust, oil, coolant etc., which reduces wear and contamination risk; but it introduces friction and must be maintained (seal replacement, correct lubrication). If improperly installed or if seal material is incompatible, sealing can fail, compromising motor internals.

It excels in robotics, CNC machinery, packaging/printing where high precision, dynamic response, and repeat positioning are required. Also suited for transfer systems or pick-and-place axes where torque at low speed and hold-in-position under load are critical.
