PH Series (A, Q, QA): INLINE — Flange Output<br />
Options<br />
<strong>Servo</strong>Cool<br />
• Used when a higher input speed is<br />
required or when improved performance<br />
and longer life is needed<br />
• Reduces operating temperatures;<br />
helpful for applications with high<br />
ambient temperature<br />
• Ideal for large planetary or units with<br />
small ratios<br />
Large . Input<br />
Accommodates a larger diameter motor shaft<br />
without going to a larger size gearbox<br />
