The R Series is a heavy-duty rack and pinion style rotary actuator that is designed to excel in the most rigid applications. The R Series includes a high torque-to-size ratio as well as accurate positioning.

Standard Specifications:

• The file hard (60 RC) high strength aluminum alloy tube provides a smooth corrosion free sealing surface and excellent abrasion resistance
• Head and cap are machined from (6061-T6) solid aluminum bar and anodized for corrosion resistance. A recess at the piston mating surface allows the air to work on a larger effective piston area for faster breakaway
• The longer cast iron rod bushing provides maximum load bearing support. The graphite-filled material offers the best bearing surface with hard chrome plated piston rod.
• The carboxilated nitrile with Teflon compound is used in the rod seal. The rounded lip design insures proper sealing and long life for no lube added service.
• Rod wiper construction is a highly durable polyurethane.
• High strength steel (100,000 psi minimum yield) piston rod has a ground, polished and hard chrome plated surface providing maximum life of bushing and seals.
• The bushing retainer allows cartridge removal without disassembly.
• Tie rods are 100,000 psi minimum yield steel for maximum holding power. Tie rod threads are rolled for strength and engagement.
• The extra wide wear band is located at the furthest point from the rod bushing to support maximum loading.
• The solid aluminum alloy piston is strong and lightweight.
• The floating cushion design gives the fastest stroke reversal possible by providing instantaneous full flow to piston. Each cushion has a flush, retained adjustment needle.
• The tube seals are compression type and reusable.
• Improved port design allows increased flow rate.
