UNIQUE COMPONENTSEXTRUDED HOUSINGBlack anodized on both the exterior and the internal bore, the housingis made of extruded aluminum with integral stators. Coating theinternal bore insures a smooth finish for lower breakaway andextended seal life. Using integral extruded stators eliminates a majorleak path common to most vane rotary actuators.DOUBLE LIP SEALSThe double-lip rotor seals of Buna-N rubber are molded onto theshaft/vane assembly. This same double-lip concept is used with thestator seal which fits over the integral extruded stators and are heldrigidly in place by the end caps. When one lip is pressurized, theother remains relaxed, lowering the breakaway pressure required tomove the vane and yet providing an extremely tight seal and improvingthe actuator's efficiency.UNIQUE SHAFT SEALINGInstead of the usual abrasive rubber-to-rubber seal, the Tol-O-Maticvane rotary actuator uses a metal-to-plastic seal. The shouldered portionof the polished, stainless steel shaft is .005 inch longer than theextruded housing. When assembled, the shaft causes a thin, highlypolished, plastic insert plate housed in the end cap to deflect slightly(0.0025 inch), creating an air-tight seal which has shown no wearafter millions of cycles of operation.ROTOR SHAFTSRotor Shafts are centerless-ground stainless steel. Vanes are made ofstamped steel bonded into machined grooves in the rotor shaft. Sealsare molded to both the vanes and the rotor shaft ensuring a tight fit.Bumpers are located in the central part of each vane, providing spacefor air inlet ports. Designed to provide maximum air flow to the vanesurface for increased effected area results in lower breakaway.END CAPSTol-O-Matic Vane Rotary Actuators have end caps with some uniquedesigns. The air ports have a tear-drop shape which make the most ofthe triangular-shaped air space created by the bumpers.End caps for the vane rotary actuators are made of machined aluminumwith a plastic insert plate and Oilite® bronze bushings. Theyare ideal for applications where high strength material is desired.2
APPLICATIONSTol-O-Matic Vane Rotary Actuators offercompact-flexibility and price competitivedurability.Used stand alone or in conjunctionwith other Tol-O-Matic motion products,the potential of Vane Rotary Actuatorsare as limitless as your imagination.Illustrated are bending, clamping, repositioningand spraying applications of Tol-O-Matic Vane Rotary Actuators. Other possibleuses include: cam indexing, positioning,damper controls, mixing and stirring,escapement feeding, shearing, automaticconveyor stop, dumping, materials handling,conveyor transfer, harmonic motion,lever motion, and valve actuators. Ourengineers and sales support teams will behappy to work with you to develop innovativeand effective solutions to your mostchallenging application needs.3
