1 Linear Busin LBLBLBBLMLMLMB Linear Busin is a i precision linear motion rollin uide wic travels alon a saft to acieve endless linear motion. In te external cylinder, a retainer, steel balls, etc. are compactly incorporated. Wide variations in size are available for selections suitable for eac application. Low frictional linear motion Steel balls are accurately uided by a retainer, so low frictional resistance and stable linear motion can be acieved. Simple replacement of conventional plain busins It is easy to use Linear Busins instead of conventional plain busins, because bot types are used wit a round saft, and no major redesin is necessary. Wide variations For eac dimensional series, standard, adjustable clearance and open types are available wit and witout seals, so te best linear busin for te application may be selected. Stainless steel type Linear Busins made of stainless steel are also available. Tis type is suitable for applications were corrosion resistance is important. xternal cylinder Retainer Steel ball Structure of Linear Busin -

5 Ratin Suarized descriptions of load ratins of Linear Busin are iven below. For details of load ratin definitions and load calculations, see "General description". load ratin Te basic dynamic load ratin is defined as te constant load bot in direction and manitude under wic a roup of identical Linear Busins are individually operated and 9% of te units in te roup can travel x meters free from material damae due to rollin contact fatiue. load ratin Te basic static load ratin is defined as te static load tat ives a prescribed constant contact stress at te center of te contact area between te rollin element and raceway receivin te maximum load. Relationsips between load ratins and te position of ball circuits ratins of Linear Busin are affected by te position of te ball circuits. In te table of dimensions, two types of load ratins are sown correspondin to te load directions and steel ball circuit positions as sown in Fi. and Fi.. In Fi. te load direction is in line wit te steel ball circuit position and tis direction is referred to as load in te table of dimensions. In eneral, te load ratins for tis direction are also used, wen te load direction is indeterminate or te steel ball circuit position in relation to te load direction cannot be determined. In Fi., te load direction is pointed at te center of two ball circuits and tis direction is referred to as load in te table of dimensions. In eneral, a larer load can be received in tis case compared wit load. Fi. Fi. -

6 Precautions for Use learance Adjustable clearance and open type Linear Busins can be adjusted for radial internal clearance if tey are used wit a ousin wic can adjust te bore. However, if te deree of te adjustment is excessive, deformation at te contact points between steel balls and saft or external cylinder becomes lare, resultin in sort life. Terefore, it is recoended to prepare a saft wit a specified fit tolerance and adjust te radial internal clearance to zero or minimal preload by matcin te individual components. Te clearance is adjusted wile ceckin wit a dial ae. Te adjustment is enerally completed wen te saft is rotated in an unloaded condition and lit resistance is caused by te rotation of saft. In tis condition, te radial internal clearance becomes zero or minimal preload. For open type Linear Busins avin tree rows of ball circuits, clearance adjustment can not be made. Fi. xample of clearance adjustment Raceway surface Since Linear Busins operate wit a saft as a raceway surface, te saft sould be eat-treated and round. Recoended surface ardness and rouness of te saft are sown in Table, and also recoended minimum effective ardenin dept of te raceway is sown in Table. LB, LB, LBB, LM, LM, LMB Table Surface ardness and rouness of raceway Table Minimum effective ardenin dept unit : Item Recoended value Remarks Surface ardness Surface rouness HR.mRa or better (.mry or better) Wen te raceway ardness is less tan te necessary ardness, multiply load ratins by te ardness factor. Wen te required accuracy is not severe, a surface rouness of about.mra (.mry) is adequate. over incl. Recoended minimum effective ardenin dept.... =.kf=.lbs. =.97inc -7

7 Lubrication Linear Busins can be used wit oil or rease lubrication. A ood quality litium-soap base rease is recoended for rease lubrication. Wen rotational motion is present Linear Busins can only be operated in linear motion and can not be rotated. Wen linear motion in sort stroke lent and rotation are bot required, Stroke Rotary Busin (See pae -7.) is recoended. If linear motion in lon stroke lent and rotation are bot required, a combination of Linear Busin and eedle Roller Bearin as sown in Fi. is recoended. Spacer Sell type eedle Roller Bearin Stop rin Fi. xample of confiuration for lon stroke linear motion and rotation Precaution for use of Linear Busin avin tree rows of ball circuits Linear Busins avin tree rows of ball circuits can be used only for te load direction sown in Fi.. If two Linear Busins are used in parallel, by considerin te load distribution, te arranement sown in Fi. is recoended. Tis type can not be adjusted for radial internal clearance. Fi. Fi. -

8 Precautions for Mountin Fit Table sows te recoended fit tolerances for Linear Busin. Te fit between Linear Busin and ousin is usually clearance fit. For some special applications, an interference fit may be required. For adjustable clearance or open type Linear Busins, te followin recoendations apply. Te saft is finised smaller tan te lower limit of te tolerance rane of te inscribed circle of te Linear Busin, wile te ousin is finised larer tan te upper limit of te tolerance rane of te outside of te external cylinder of te Linear Busin. Table Recoended fit tolerance Item Housin Type ormal clearance loser clearance learance fit Interference fit LB, LBB LM, LMB LB, LM Hi class class f, f, j H7 H H7 J7 J J7 Mountin Wen press-fittin te Linear Busin into te ousin, do not it te end plate. Te correct metod is to radually pus te external cylinder wit a ji for assemblin. (See Fi. 7.) Ten te external cylinder is fixed in te axial direction wit a stop rin or a stopper plate. Wen insertin te saft into te Linear Busin assembled into a ousin, radually and ently insert a saft avoidin to ive impact on te steel balls and retainers. If two safts are used in parallel, fix one saft accurately as a datum saft and locate te second saft to te datum saft keepin te parallelism.
