ROTEX 3X Difference

ROTEX 3X Difference

Rotex Infinity actuators are engineered to provide the longest possible service life. The exclusive Rotex V-Seal polymer double lip seal offers the most efficient, dynamic sealing in the industry.

Massive bearings with greater surface area allow for higher load capacity. Monolithic billet pinion provides for incredible strength and durability. Two part epoxy paint over anodized aluminum body gives superior corrosion protection. Infinity actuators are greater than the sum of their parts.

Rotex Controls Inc. warranties the complete actuator for 3 years or 3 million cycles, including all seals. All major components, including body, pinion, bearings, springs, seals, and all hardware are covered for the full term of the warranty, 3 years or 3 million cycles. No other actuator manufacturer stands behind their product the way Rotex Controls Inc. does. If one fails, ship us the old one back, and we will ship you a new one!
