Drive Mechanism and Type
   Drive Mechanism       
   Your choices are...         
   None / Direct Drive       The unit does not have an integral drive mechanism, or it is directly driven from the motor or actuator (as is the case with most linear motor slides and stages).  A product without a drive mechanism is often called a slide. 
   Ball Screw       A ball screw uses recirculating steel balls, which roll between the screw and the ball nut.  Rolled screws are cold rolled from a blank. Typically, this produces a screw with a 0.004 inch per foot accuracy.  Ground screws are made on a grinding wheel with an Acme form. Typically, this produces a screw with 0.0005 inch per foot lead accuracy. 
   Lead / Acme Screw       A typical lead screw has a "V" thread.  It is relatively easy to machine and roll form.  A “V” thread has an angle of 60° between opposing faces. Acme screws use plastic or bronze solid nut.  An Acme screw is a specific type of lead screw.  An Acme thread has an angle of 29° between opposing faces.  Acme screws provide motion through direct sliding friction between nut and lead screw. Rolled screws are cold rolled from a blank. Typically, this produces a screw with a 0.004 inch per foot accuracy.  Ground screws are made on a grinding wheel. Typically, this produces a screw with .0005 inch per foot lead accuracy. 
   Belt, Band, or Cable and Pulleys       The linear motion is produced by a timing belt, band, or cable and pulley system. 
   Micrometer       A micrometer produces the linear motion. 
   Rack & Pinion       Rack and pinion gears are used to convert rotation into linear motion.  
   Other       Other unlisted, specialized, or proprietary drive mechanism. 
   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.
   Ground Screw       Ground screws are made on a grinding wheel. Typically, this produces a screw with 0.0005 inch per foot lead accuracy. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Drive Type:       
   Your choices are...         
   None       The unit does not contain an integral drive. 
   Handwheel / Crank       The unit does not contain an integral motor drive.  It is a handwheel or crank handle drive. 
   Motor Mount (No Integral Motor)       The unit does not have an integral motor, but it does come equipped with motor mounts or couplings for mounting a motor that is supplied by the user. 
   AC Motor       The unit contains an integral AC motor.  AC motors include single / multiphase, universal, servo, induction, synchronous, and gearmotor types. The magnetic field, generated by AC motors, is produced by an electromagnet powered by the same AC voltage as the motor coil. 
   Brushless Servo       The unit contains an integral brushless servomotor.  Servomotors are generally small and powerful for their size, and easy to control.  Brushless motors are a typical type of DC servomotor. 
   DC Servo       The unit contains an integral DC servomotor.  Servomotors are generally small and powerful for their size, and easy to control. 
   Linear Motor (Direct Drive)       The unit contains an integral linear motor.  A linear motor generates force only in the direction of travel. 
   Stepper Motor       The unit contains an integral stepper motor.  A stepper motor uses a magnetic field to move a rotor in small angular steps or fractions of steps. 
   Pneumatic       The unit contains an integral pneumatic motor.  Pneumatic motors are powered by compressed air and many operate at relatively high speeds in industrial and spark-prohibited applications.  
   Hydraulic       The unit contains an integral hydraulic motor.  Hydraulic motors are powered by pressurized hydraulic fluid and transfer rotational kinetic energy to mechanical devices. 
   Other       Other unlisted, specialized, or proprietary drive type.

Bearing / Guide Mechanism Type
           
   Your choices are...         
   Air Bearing       Air bearings ride on a thin cushion of air along the slide length. Air bearings have virtually zero friction and are very low noise.  An air bearing provides support in one direction.  They must be stacked or coupled in order to provide multi-axis positioning in the same plane.  Air bearings provide a high level of accuracy, and they are well suited to clean rooms.  They are not capable of movement in the Z-axis (vertical lift). 
   Ball Slide       These are sometimes referred to as ball and rod bearing assemblies, or ball bearing slides.  Ball slide stages are simply ball slides coupled with a drive mechanism.  The result is a very smooth linear motion, accurately controlled by rotation of the drive mechanism.  Ball slides use a bearing system composed of two rows of balls on both sides of the base. Each row is contained between four rods. These two rows of balls are preloaded to eliminate play. As the carriage moves, the balls roll along the rods.  Ball slides provide smooth, accurate, low friction motion.  They are typically very reliable, and because there is no direct sliding contact between the base and carriage, they do not require regular lubrication. 
   Ball Spline       The ball spline shaft is not round in shape.  There are a few varieties of ball spline shafts, all with ground grooves for recirculating balls to run inside.  The ball housing is called a nut, and contains 4 or 6 sets of ball retainers.  The contact area of the balls is increase, increasing the load carrying capacity.  Ball spline assemblies are capable of functioning in a strenuous work environment. 
   Crossed Roller       The rollers are 'crossed' 90° in an alternating fashion.  They are enclosed in the rails, which have a machined 'V' groove to support the rollers.  The 'V' grooves are precisely ground at 90°.  The rollers contact the grooves only on their diameter.  This generates a rolling motion and minimizes friction.  Crossed roller bearings are capable of a much higher load carrying capacity than the similar ball bearings. 
   Dovetail Slide       Dovetail slides may also be called dovetail way slides.  A dovetail is a flaring tenon and a mortise into which it fits, making an interlocking sliding joint between two pieces.  The dovetail slide is a direct contact system where the sliding area is considered the bearing system of the dovetail slide.  Since the surface contact is so large, dovetail slides are ideal for heavy load applications and industrial uses. 
   Hardened Way Slide       Also called box ways, industrial hardened ways, hardened slides or rectangular way slides. Hardened ways have many similarities to the dovetail slide. The hardened way is a more durable product and is meant for applications with heavy loads and high cyclic action. The hardened way utilizes the direct contact of the base and saddle. Since friction is higher in these direct contact bearing systems, the iron cast surfaces are finely ground to produce a lower coefficient of friction. The hardened way slide has a very dense rigid structure to enable these slides to handle massive industrial applications. 
   Linear Bushing       The linear bushing may also be called a ball bushing, round rail bearing or recirculating ball bearings.  It contains recirculating linear bushings, a shaft, shaft support, and a carriage.  The shaft supports may come in two different styles, continuous support or end support.  The recirculating balls spaced evenly around the bushing make contact.  Since the surface area is small the frictional resistance is also small.  However, the accuracy and smoothness is poor.  The carriage is mounted to the bushing usually on two separate but parallel shafts. 
   Linear Motion Guide       A linear motion guide may also be referred to as a linear guide bearing, square rail linear bearing, linear guideway, or recirculating ball bearing.  This type of linear guide system is made up of two components; the guide rail and the carriage unit.  The rails may come in a variety of cross sections all with machined grooves for the bearings to run in.  The balls are contained on the carriage.  The linear motion guide has a superior load carrying capacity and is suited for use in dirty environments.  However, straightness accuracy, flatness accuracy, and smoothness are sacrificed.  
   Needle Roller (M/V Ways)       Needle roller bearings are often referred to as M/V ways.  Needle rollers are contained in cages mounted on matching machined rails.  Needle rollers are similar to roller bearings but they are longer than the diameter.  The rails are often machined with one in a 'M' shape and the other matching rail in a 'V' shape.  Needle rollers offer a high load carrying capacity and are very rigid. 
   Plain Bearing / Sleeve Bushing       Bushing is cylindrical in shape with straight inside and outside diameters. 
   Other       Other unlisted, specialized, or proprietary bearing / guide mechanism.
