HOW TO SIZE A COMPACT SERVO POWER UNIT (SPU)

When sizing a compact Servo Power Unit (SPU), three primary factors determine proper configuration: flow requirements, system pressure, and cylinder specifications.

In this video, Mark McCloskey of Kyntronics walks through how to properly size a Compact Servo Power Unit for your application. He explains how flow and speed requirements influence servo motor and pump selection, how system pressure impacts overall performance, and why understanding cylinder bore, rod size, and stroke length is essential for accurate sizing.
