Advantages Disadvantages
Shorter maintenance Shorter cycle time between
times maintenance
Small foot print Less tolerance to upsets
Low specific weight Shorter bearing life (anti-friction
Higher efficiency bearings)
Faster start sequence
Note: maintenance cycle time is increasing and approaching
industrial types
