2 atents 1. reface A linear guieway allows a type of linear motion tat utilizes rolling elements suc as balls or rollers. y using rolling elements between te rail an te carriages can acieve muc lower friction tat is compare wit te traitional slie an provie muc smooter running. Furtermore, epening to our outstaning process capability, we can offer te intercange of ig accuracy to customers for easy maintenance an replacing. 2.aracteristics 2.1 ower Frictional Resistance it using te rolling element to replace of te traitional sliing one, te friction coefficient is only 1/5 of traition friction. 2.2 ig ositioning Accuracy Te rolling motion wit a low friction coefficient, an te ifference between ynamic an static friction is very small. Terefore, tere woul be no slip wile te loa is moving. 2.3 ow ower onsumption ue to te caracteristic of low frictional resistance, te require riving force is muc lower tan in oter systems, tus te power consumption is small. Moreover, te temperature rising effect is small even uner ig spee operation. 2.4 Four-way qual oa Te optimum esign of geometric mecanics makes te linear guieway to bear te loa in all four irections, raial, reverse raial, an two lateral irections. 2.5 Intercangeability Superior processing ability can offer te linear guieway ig precision an make customers use an maintain easily, an also acieve original igly accurate linear motion. 2.6 asy ubrication it a special lubricating esign of te linear guieway, it is possible to equip various grease nipples an piping joints, an ten to effectively fill te grease or lubrication oil into te carriages. 1

Terefore, te basic static loa rating sets a limit on te static permissible loa. 4.2 Static ermissible Moment (M ) en a moment is applie to a linear guieway, te rolling balls on bot ens will receive te most stress among te stress istribution over te rolling elements in te system. Te static permissible moment (M ) refers to a static moment in a given irection wit specific magnitue applie at te contact area uner te most stress were te sum of permanent eformation evelops between te raceway an rolling elements is.1 times te iameter of rolling elements. Terefore, te static permissible moment sets a limit on te static moment. In linear guieway system, te static permissible moment is ene as M, M Y, M R tree irections. See te gure below.

4 4.4 asic ynamic oa Rating Te basic ynamic loa rating () is ene as a loa in a given irection an wit a given magnitue tat wen a group of linear guieways operate uner te same conitions. As te rolling element is ball, te nominal life of te linear guieway is 5 km. 4.5 alculation of Nominal ife Te life of linear guieway is efine as te total istance travele until fatigue flaking appears on te surface of te raceway or rolling elements. ven wen te linear guieways are manufacture in te same way or operate uner te same motion conitions. For tis reason, nominal life is use as te criteria for preiction te service of a linear guieway. Te nominal life is te total istance tat 9% of a group of ientical linear guieways, operate uner te ientical conitions, can travel witout flaking. ase on te selecte basic ynamic rate loa() an actual loa(), te nominal life of linear guieway can be calculate. =( f x f t x f x ) 3 x5 (km) 4.6 Factors of normal life : Nominal life (km) : asic ynamic loa rating (N) : orking loa (N) f : arness factor f t : Tempature factor f w : oaing factor As te above mentione about te calculation of nominal life of te linear guieway, wic te factors about te arness, temperature an loa will affect te nominal life of te linear guieway, te relate coefficient is as te following explanation arness factor In orer to ensure te optimum loa capacity of linear guieway system, te arness of raceway must be R58~64. If te arness is lower tan tis range, te permissible loa an nominal life will be ecrease. For tis reason, te basic ynamic loa rating an te basic static loa rating soul be multiplie by arness factor for rating calculation. See figure below. Te arness requirement of ATAK linear guieway is above R58~64, tus te f = Temperature factor en operating temperature iger tan 1, te nominal life will be egrae. Terefore, te basic ynamic an static loa rating soul be multiplie by temperature factor for rating calculation. See figure below. Te assemble parts of ATAK guieway are mae of plastic an rubber, terefore, te operating temperature below 1 is strongly recommen. For special nee, please contact us oa factor Altoug te working loa of linear guieway system can be obtaine by calculation, te actual loa is mostly iger tan calculate value. Tis is because te vibration an impact, cause by mecanical reciprocal motion, are ifficult to be estimate. Tis is especially true wen te vibration from ig spee operation an te impact from repeate start an stop. Terefore, for consieration of spee an vibration, te basic ynamic loa rating soul be ivie by te empirical loa factor. See te table below. 5. reloa an Rigiity Te rigiity of a linear guieway coul be enance by increasing te preloa. Te preloa is represente by negative clearance resulting from te increase of rolling element iameter. Terefore, te preloa soul be consiere in calculation service life.

5 7. ubrication Supplying te sufficient lubrication to te linear guieway will greatly reuce te rolling friction an increase te service life. Oterwise, te lubrication also prevent from corrosion. Generally, te linear guieway usually use lubrication grease an lubrication oil. It will be cosen by customers options. 7.1 Grease After te linear guieway installe, we recommen te guieway be re-lubricate every 1 km. It is possible to carry out te lubrication troug te grease nipple. Generally, grease is applie for spee tat o not excee 6 m/min faster spee will require igviscosity oil wit a lubricant. Te stanar grease is litium-base grease No Oil Te recommen viscosity of oil is about 3~15 cst, an te recommen oil fee rate is approximate.3 cm3/r. 7.3 Grease nipples an piping joints ATAK offers te following various grease nipples an piping joints to customers options. 8. ust proof ATAK offers various contamination protection against ifferent environments for linear guieway. oe ust proof Application No Symbol Metallic Scraper (ot sie) ow resistance an cleaner environments UU iirectional en seal(bot ens) ow resistance SS iirectional en seal + ottom seal Normal environments ZZ SS + Inner seal+ Metallic scraper revent large steel cips KK ouble biirectional en seal + ottom seal + Inner seal + Metallic scraper igly ust-proof requirement revent large steel cips an igly ust-proof requirement n Seal Metallic Scraper Grease Type 8 7 ottom seal M6x M6x M4x.7 SS ayout ZZ ayout iping Type T1/ M8x M6x M6x M6x M4x.7 6 7

It features equal loa rating, reverse raial an lateral irection, self-aligning to absorb te installation-error, an use an install easily. 9.1 aracteristics of GA Series Self Alignment apability it te esign of F circular-arc groove, GA Series can absorb most installation errors ue to surface irregularities an provie te smoot linear motion troug te sift of contact points an te elastic eformation of rolling elements Four-way qual oa ecause of te four-row esign, te GA Series linear guieway as equal loa rating in te raial an lateral irection Optimal esign It reuces te overall contact eigt between te carriage an rail as well as uses a larger iameter of te ball. ompare to our Spec. 2 wic can provie about more 3% of loa rating an rigiity tan oter lower specification of oter factories. Moreover, compare to te stanar specifications of oter factories, te anti-twiste capacity is iger 12%. Also, in orer to provie ig locking force, we offer te longest screw ept of carriage installation Intercangeability ecause of precision imensional control, te imensional tolerance of GA Series can be kept in te reasonable range, wic means tat te blocks an any rails in specific series can be use togeter wile maintaining imensional tolerance ommon rail is esigne for ifferent ig carriages, moreover, we use big balls for eavy loaing. So tis is easy for customer's stock an selection ig smootness it a special grining process, te balls will roll smootly even wen te rolling surface is not iscontinuities. eter te preloa wit, any vibration can be effectively reuce by about 2% uring operation, lowering te ram troug te ball, an to improve te life Sort Stroke ubrication atente oil circuit esign, wic provies coosing to lubricate te ball irectly wen using te sort stroke an to prevent lack of lubrication cause service life to reuce. 9.2 onstructions arriage 9.3 escription of Specification GA Series guieway can be classifie into non-intercangeable an intercangeable types.
