Rotary ctuator The 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. Rack and Pinion The rack and pinion is made from high strength alloy steel. It is induction hardened for long life. The geometry factors of the rack and pinion have been balanced to ensure equal wear, which provides maximum gear life. The pinion shaft includes a male key as standard offering. Ball Bearings The ball bearings are sealed and prelubed in an effort to prevent contamination from negatively affecting the operation. They are sized to except high loads and still retain smooth maintenance free operation. Rack Bushing The rack bushing is made from bearing bronze. The durability of the bushing enables it to support nearly the full length of the rack. Furthermore, we have included a small gap to allow grease/lubrication to be added. Tube The profile tube is hard coat anodized. The hard coating is an electrochemical process, which produces a very dense surface of aluminum oxide. This surface has extreme hardness (60 R.), excellent wear and corrosion resistance, and low coefficient of friction. End aps The end caps are accurately machined from (606-T6) solid aluminum bar stock. They are anodized for corrosion resistance. dditionally, port positioning is extremely flexible. Rod Seal The carboxilated nitrile with Teflon compound rod seals is selflubricating and durable. The rounded lip design ensures proper sealing and long life. Tie Rods The tie rods are 00,000 psi minimum yield steel for maximum holding power. They are roll formed for superior strength and engagement. Piston The solid aluminum alloy piston is strong and durable. magnet groove is standard allowing for easy field conversation. Piston Seal The piston seal is a carboxilated nitrile with Teflon compound for self-lubricating. The U-cup type seal construction is proven and durable. Wear Band The wear band is a stable, lubricating strip located on the piston. Grease Opening /-8 tapped hole (which is plugged) is provided for future installation of an optional grease fitting. Note that the unit is pre-lubed. Teflon is a registered trademark of DuPont. For detailed information regarding the properties of Teflon, please call -800--07.

Options Rotary ctuator Rotation djust Rotation adjusting knobs can be added to control rotation more precisely. They can be used on both ends or on either end individually. Rotation adjusters can be used in conjunction with cushions. Their "high tech" style makes rotation adjustment easy to do without tools. The metric set screw in the side of knob securely locks the rotation setting. Thus, the rotation is very easy to adjust, but cannot be changed without a metric allen wrench. When used with cushions, maximum rotation adjustment will still allow at least 0 o of rotation to be in cushion. ushions Seals Into ushion Out of ushion ushions can be added to meter deceleration. ushion adjustment needles can be put in any quadrant. Normally, cushions will be added to only one half of the double rack unit. The cushion and its operation is very similar to our current series design. Rotation adjust can be used in conjunction with cushions. ushions and Shock absorbers together are not available. Bumpers Bumper seals can be added to reduce impact. The bumper and seal are one piece. Bumpers can be used in conjunction with cushions if necessary. NOTE: annot be used with rotation adjustment. Shock bsorbers Hydraulic shock absorbers can be added to reduce noise and large impacts. Shocks are fixed orifice selfcompensating type. They can also be used for rotation adjust. The /" bore rotary actuator will not have this option. ushions and shock absorbers together are not available. NOTE: Shock cannot be adjusted. øb BORE B / / / Our cushion seal has a built-in function. It seals in one direction and permits full flow in the opposite direction......67...7.7.
