Question by: Lance W on Jan 8, 2026, 9:15 AM
Reckon this'll hold up alright coupling a hydraulic pump to a motor, or is it more for lighter duty stuff?
Answer by: Customer Support on Jan 9, 2026, 12:35 PM
It's typically used to couple hydraulic pumps to electric motors, and should do the job well. Just be sure you aren't exceeding the maximum angular offset of 1 degree or a parallel offset of 0.015 inches.
