High SpeedThrough the use of Caged Ball Technology, the SKR-type is compatible with the latest high-speedrotational AC servo-motors (6000 min -1 ), achieving higher speeds than the conventional KR-type.The ball screw lead settings of the conventional KR33 type were 6 mm and 10 mm. To achieve ahigher feed rate, a 20 mm ball screw lead has been added to the new SKR 33 series.Table 3 Maximum Traverse RateModel No.Ball Screwlead (mm)LM rail length(mm)Maximum travel speed (mm/s)Long block Short block150600200600300600064006005006006005525307003933641501,0002001,0003001,000SKR33104001,0005001,0006009208397006566071502,000—2002,000—3002,000—204002,000—5002,000—6001,780—7001,276—3401,000—4401,000105406401,0001,000914740736667SKR469403404312,0004004402,000205406401,9882,0001,7747401,4331,300940845784The maximum travel speed of the SKR-type is limited by the critical speed of the ball screw shaft, regardless ofthe maximum rotational speed (6000 min -1 ) of the motor. Please keep this in mind when using the SKR-type inhigh-speed applications.Please contact THK if you are considering using an SKR model at a rate higher than the maximum travel speednoted above.3

(495) 727-22-72Load Rating and Static Permissible Moment in Each Direction● Load RatingThe SKR-type LM guide actuators with Caged BallTechnology consist of the LM guide, ball screw,and support bearing. Table 4 shows the load rating.P TP LP RP T• LM guide section unitThe SKR-type can carry loads in all directions, i.e., the radial, reverse-radial, and two lateral directions. Thebasic load rating is the same in these four directions and their values are shown in Table 4.• Ball screw section unitThe SKR-type can carry loads in the axial direction since it incorporates a ball screw nut in the nut block. Thebasic load rating value is shown in Table 4.• Support bearing unitThe SKR-type can carry loads in the axial direction since it incorporates an angular bearing in housing A. Thebasic load rating value is shown in Table 4.● Equivalent Load (LM Guide Unit)When loads are simultaneously applied to the SKR-type's LM guide in all directions, the equivalent load isobtained by the following equation.P E= P R(P L) + P TP E: equivalent load (N)In the radial directionIn the reverse-radial directionIn the lateral directionsP R: radial load (N)P L: reverse-radial load (N)P T: load in the lateral directions (N)Table 4 Load ratingBasic dynamicload rating C (N)ModelLong nut block types A, BShort nut block types C, DSKR331700011300LM GuideBasic staticLong nut block types A, B20400load rating C0 (N) Short nut block types C, D11500Radial clearance (mm)Normal grade, high accuracy grade 0 to –0.004Precision quality grade–0.004 to –0.012Screw shaft outer diameter (mm)13Lead (mm)6 10 20Ball ScrewThread minor diameter (mm)10.8Ball center-to-center diameter (mm)13.5Basic dynamic load rating Ca (N)4400 2700 2620Basic static load rating C0a (N)6290 3780 3770SupportBearingBasic dynamic load rating Ca (N)Static permissible load P0a (N)62502700Notes: • The load rating of the LM guide is the load rating per nut block.• Model SKR3320 has no short type block.SKR46395002840045900287000 to –0.006–0.006 to –0.0161510 2012.515.754350 42406990 7040670033306

www.thk.ru thk-mail@ya.ru Тел. (495) 727-22-72Accuracy StandardsThe precision of the SKR is determined by repetitive positioning repeatability, positioning accuracy, backlash, and runningparallelism.● Positioning RepeatabilityRepeat the measurement seven times from the samedirection to a certain point. Divide the maximum differenceby two. Conduct the same test at three points, the “center”of the stroke, and on both the approximate maximum andminimum positions of travel. Add ± to the largest difference.This accuracy is generally measured with a laserinterferometer and sometimes with a dial-gauge.(Taken from THK Accuracy & Measurement Standards.)t1t2t3Figure. 8 Positioning Repeatability● Positioning AccuracyThe maximum stroke is taken as the reference length, andthe maximum error between the actual distance traveledfrom the reference position and the instructed value isexpressed as an absolute value.(+)A(Error)Referenceposition0A Instructed valueA Distance traveledA=| Distance actually traveled –Instructed travel distance value(-)Figure. 9 Positioning Accuracy● BacklashLock the actuator’s carriage into a fixed position via theactuator’s drive mechanism. Do not lock the actuator’scarriage by “fixing” it rigidly. Push the carriage from onedirection with a predetermined external force using a push/pull gauge. Zero out the dial-gauge while the axial force isbeing applied-release the external force and read the dialgauge.Measure at three separate points along the stroke,at the center and the end of travel positions. Backlash isthe maximum measured value.BacklashScrew feedLoadReturnLoad displacement(including elastic displacement)Figure. 10 Backlash● Running of ParallelismA straightedge is placed on a leveling plate mounted withthe SKR, and parallelism is measured over almost the entiredistance traveled using a test indicator.
