NIBCO Pneumatic Actuation


Improved Travel Stop Design

The improved travel stop design allows the actuator to stop off the pinion rather than the pistons. A standard actuator will have 100 degrees of travel with +5 or -5 degrees of adjustment on the open and close stop. The forged steel travel stop can be machined to any length of travel.

Upgraded Top Hat Thrust Bearing Design


The upgraded top hat thrust bearing design provides the largest pinion bearing surface in the industry. This upgraded thrust bearing limits friction between the actuator body and pinion, increases durability by absorbing side-load forces and extends the cycle life of pinion O-rings.
