Drive Type




   Drive Type       
   Your choices are...
 
      
 
   Pneumatic
 
     Pneumatic linear thrusters use double acting air cylinders mated to plates and shafts to provide cyclical linear motion.
 
   Hydraulic / Electrohydraulic
 
     Hydraulic linear thrusters use double-acting hydraulic cylinders that are mated to plates and shafts to provide cyclical linear motion. Electrohydraulic linear thrusters are electrically-actuated devices, typically with double-acting hydraulic cylinders that are mated to plates and shafts to provide cyclical linear motion.
 
   Electric
 
     Electric linear thrusters are electrically-actuated devices.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Drive Configuration:       
   Your choices are...
 
      
 
   Lead Screw
 
     A lead screw with matching threads on the screw and nut.
 
   Ball Screw
 
     A lead screw and ball nut combination where the balls in the nut circulate when in motion.
 
   Belt Drive
 
     A belt connects the motor to the actuator. May be used in both rod and rodless actuators.
 
   Direct Drive
 
     The motor is connected directly to the actuator.
 
   Geared Drive
 
     The motor is connected to the actuator through a set of gears.
 
   Other
 
     Other unlisted, specialized or proprietary drive configurations.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Body Material




           
   Your choices are...
 
      
 
   Aluminum
 
     A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
 
   Steel
 
     A commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
 
   Stainless Steel
 
     Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings.
 
   Plastic
 
     Any of numerous organic, synthetic, or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments.
 
   Other
 
     Any plate material not listed above.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Bearing Type




   Bearing Type       
   Your choices are...
 
      
 
   Ball / Roller Bearing
 
     Balls or rollers, typically recirculating for linear motion.
 
   Solid Metal Bushing
 
     Bushing materials such as oil-impregnated bronze.
 
   Thermoplastic / Composite
 
     Continuous surface composite bearings are sometimes recommended for their anti-corrosive properties and tolerance to debris.
 
   Other
 
     Other unlisted, specialized, or proprietary bearings.

Features




           
   Your choices are...
 
      
 
   Adjustable Stroke
 
     End points or total stroke length can be adjusted.
 
   Bumpers / Cushions
 
     Cushions or bumpers for softening impact at ends of stroke.
 
   Closed Loop Control
 
     This is sometimes called servo control. The cylinder has external devices that feedback a signal to the pump control giving it position information. A type of configuration is to use a servo / proportional valve on the cylinder.
 
   Double End Rod
 
     Rod extends out of both ends of cylinder with attachment features such as threads on both ends.
 
   Integral Flow Control
 
     Integral flow control incorporates a flow control valve or device that limits the amount of air or fluid that enters the cylinder.
 
   Integral Sensor
 
     Cylinder is equipped with an integral sensor to monitor position and/or proximity.
 
   Intrinsically Safe
 
     The cylinder can be used in hazardous environments.
 
   Magnetic Switch
 
     Magnetic switch (Hall effect sensor, reed switch) indicates whether thruster position is in retracted or extended position.
 
   Multi-position
 
     Endplate can be actuated to different positions along its stroke, not just the endpoints.
 
   Non-rotating
 
     Multiple rods or key feature to prevent the plunger from rotating.
 
   Protective Boot
 
     Covers that protect moving parts against environmental damage.
 
   Self-locking
 
     When there is a loss of signal, the device will lock to its current position.
 
   Shock Absorbers
 
     Pneumatic or hydraulic fluid absorption of shock.
 
   Thermal Overload Protection
 
     Motor has a thermal switch which trips when a preset temperature is exceeded.
 
   Water Resistant (Sealed)
 
     Rated to resist moisture which could cause corrosion.
 
   Other
 
     Other unlisted, specialized, or proprietary
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
