3 Linear Roller Way Super X is a linear motion rolling guide, featuring high reliability, high rigidity, high accuracy, and smooth motion. our rows of cylindrical rollers are incorporated in a highly rigid casing, and the cylindrical rollers in each row are arranged in parallel to each other in well-balanced form to take full advantage of the excellent characteristics of cylindrical rollers. Super high rigidity Rigidity of linear motion rolling guide has a large influence on the performance of machines or equipment in which they are assembled. Very high rigidity of Super X is achieved owing to the excellent elastic deformation characteristics of cylindrical rollers which give smaller elastic deformation under load as compared with steel balls, and, in addition, to a large number of cylindrical rollers incorporated in the slide unit.

Incorporating a large number of cylindrical rollers, Super X has very high load ratings. xcellent load balance and moment load capacity Cylindrical rollers are arranged in a well-balanced form so that they can uniformly withstand loads in all directions. In addition, rows are arranged in such a way that the moment arm distance between the loading points is large under T0 moment. A high moment load capacity can be obtained Structure of Linear Roller Way Super X Grease nipple Casing Cylindrical roller Under seal Retaining plate nd plate nd seal U.S. PATT o.,800,0 o.,193,91 o.,0,22 o.,,188 o.,37, o.,22,33 o.,17,17 o.,97,7 o.,,288 Basic static load rating LRX (Roller type) LW... B (Ball type) Size Comparison of basic static load ratings Low noise and high running performance Smooth and quiet motion is achieved by adopting the optimum design based on the analysis of roller re-circulation behavior. urthermore, as the number of load carrying cylindrical rollers is large, the minute fluctuating deflection during travel can be minimized. When T0 moment is applied Accurate positioning with excellent friction characteristics A unique roller retaining method is adopted, in which the end faces of cylindrical rollers are guided accurately by the retaining plate, so skew of cylindrical rollers is prevented and smooth motion is achieved. As compared with the slide guides and ball type linear motion rolling guides, Super X has superior frictional characteristics and gives small frictional resistance even under preload. Good response to micro feed and high positioning accuracy can thus be achieved. 3

6 asy to use Interchangeable Specification, Three eatures of Interchangeability The track rails and the slide units of interchangeable specification Linear Roller Way Super X can be handled separately and can be assembled to make a set as required. Interchangeability of incomparable high level has been achieved through rigorous dimensional control of the slide units and the track rails on the basis of the original advanced manufacturing technology. At a time like this! Want to improve the rigidity and life of the machine Want to improve the accuracy of the machine Want to replace slide units right away umber of slide units insufficient Want to replace track rails right away Length of track rails not long enough Want to stock spare slide units for emergency Interchangeable specification can be useful. Urgent design change can be made. igh-accuracy and preload can be selected freely. s and track rails can be handled separately and combined freely. s and track rails can be stocked individually requiring only small stock area. A new product selection system is offered, in which slide units and track rails can be selected separately, as and when required!! Interchangeable slide unit Interchangeable with high accuracy Interchangeable with preload Various types of slide units with different sectional shapes and lengths are prepared. All of these slide units can be freely mounted on the same track rail. It is also possible to combine a slide unit and a track rail of different materials, for example, a high carbon steel slide unit and a stainless steel track rail can be combined. In addition, butt-jointing interchangeable track rails (supplemental code /T) can be butt-jointed for use. Two accuracy classes, igh and Precision are prepared for the interchangeable specification products so that these products can be used for applications requiring high running accuracy. eight variation among multiple sets is also controlled at a high accuracy level, ensuring that these products can be used for parallel track rail arrangement. igh accuracy dimensional control owing to a simple structure has made it possible to realize the interchangeability among preloaded slide units. These products can be used for applications requiring one step higher rigidity. igh carbon steel track rail C s with the same preload symbol are interchangeable for achieving high rigidity. lange type Block type Compact block type Stainless steel track rail Butt-jointing interchangeable track rail A D B Deflection m 0 LRX T2 preload LRX T3 preload Short Standard igh rigidity long Load

Therefore, periodic re-lubrication is necessary. The re-lubrication interval varies depending on the operating conditions of the rolling guides. A six month interval is generally recoended and, if the machine operation consists of reciprocating motions with many cycles and long strokes, re-lubrication every three months is recoended. Re-lubrication is performed from a grease nipple provided at the slide unit. Re-lubrication interval can be extended by using the special specification Capillary Platesupplemental code /Q. Also, re-lubrication and other maintenance works can be reduced. Linear Roller Way Super X is dust-protected with special rubber seals. But, if large amounts of fine contaminants are present, or if large particles of foreign matter such as dust or chips may fall on the track rail, it is recoended to provide protective covers such as bellows or telescopic shields for the entire linear motion mechanism. Bellows to match the dimensions of Linear Roller Way Super X are optionally available. They are easy to mount and highly effective for dust protection. If required, consult.

It is suggested in such cases to assume a greater load than the calculated load. qwhen mounting multiple sets at the same time In the case of interchangeable specification Linear Roller Way Super X, assemble a slide unit and a track rail with the same interchangeable code S1 or S2. In the case of non-interchangeable specification Linear Roller Way Super X, use an assembly of slide unit and track rail as delivered without changing the combination. Special specification products of matched sets supplemental code /W are delivered as a group in which dimensional variations are specially controlled. Mount them without mixing with the sets of another group. wassembling a slide unit and a track rail When assembling the slide unit on the track rail, correctly fit the grooves of the slide unit to the grooves of the track rail and move the slide unit gently in parallel direction. Rough handling will result in seal damage or dropping of cylindrical rollers. The interchangeable specification slide unit is provided with a duy rail. The size, 1,, 2 and models of non-interchangeable specification are appended with a duy rail. This duy rail should be used for assembly. eaccuracy of mating mounting surfaces A load greater than the calculated load may act on Linear Roller Way Super X, depending on the accuracy of mating mounting surfaces and assembling accuracy. This will eventually give an adverse effect on the service life of Linear Roller Way Super X. Therefore, the accuracy must be carefully examined. The accuracy of mating mounting surfaces for track rail and slide unit and the assembling accuracy must be determined considering the operating conditions, required running accuracy and rigidity, etc. Also, the mounting structure must be examined to ensure accuracy and performance for reliable use of a linear motion rolling guide. When multiple sets are mounted, the parallelism between the two mounting surfaces of machines must be prepared, in general, as shown in Table 1. Table 1 Parallelism between two mounting surfaces Accuracy class igh Precision P Super precision SP unitm Ultra precision UP ig. 8 Cleaning of mounting surfaces ttightening torque of mounting bolts The standard torque values for Linear Roller Way Super X mounting bolts are shown in Table 1. When machines or equipment are subjected to severe vibration, shock, large fluctuating load, or moment load, the bolts should be tightened with a torque 1.2 to 1. times higher than the standard torque values shown. When the mating member material is cast iron or aluminum, tightening torque should be lowered in accordance with the strength characteristics of the material.
