1 T E C H N I C A L LINEAR MOTION Introduction drlin T slide guide rails were developed for applications in the automation and handling industries. Rather than etreme precision the development objective was a robust linear guide sstem for reliable use in the widest range of different environments. drlin T guide rails are shock and have an etremel low weight design. drlin T slide guide rails are eceptionall quiet in operation because there are no moving parts or metallic rollers. Special Characteristics No lubrication necessar Adjustable clearance Replaceable sliding inserts Quiet operation Resistant to dust, dirt and moisture Corrosion High static load rating in all directions Low weight Shock and vibration Ecellent wear resistance Static Load-Bearing Capacit Tpe C 0Y (N) 4,000 7,400 10,000 14,000 M o C 0(-Y) (N) 4,000 7,400 10,000 14,000 C 0Z (N) 2,000 3,700 5,000 7,000 M 0X (Nm) lightweight hard anodised aluminium guide profile rail lightweight aluminium/ plastic slide carriage Iglidur J sliding inserts abrasion free to dust and dirt ver quiet running adjustable clearance maintenance-free dr operation corrosion no seals necessar Design drlin T slide guide rails consist of carriages mounted on the rail. 1. The rail, together with the basic bod of the wagon, is made of aluminium Al Mg Si 0.5. The rail is hard anodised and the aluminium bod of the slide is clear anodised. 2. The guide bearing consists of si opposing pairs of slide inserts made of Iglidur J. 3. One side of each of the three guide can be infinitel adjusted in height. 4. All steel parts are galvanised. 5. The end covers are made of plastic. Dimensions The mounting directions of the drlin T slide guide rails are interchangeable with the usual recirculating ball guides. The drlin T slide rail guides offer further advantages compared to other linear guides: Ver high accelerations possible Etreme speeds can be attained quickl Minimum effort for assembl Replaceable slide inserts Maintenance free Corrosion

2 LINEAR MOTION Calculation For the eact calculation of the drlin T linear guide sstem it is essential to find out whether the position of the forces is within the allowed limits and if the sliding element where the highest forces occur is not overloaded. The calculation of the possible driving force and the maimum speed allowed is important. The position of the guiding sstem leads to different formulas for calculation. ctors concerning shocks and acceleration forces are not included in the calculation, therefore the distance between maimum load and allowable load has to be observed. This analsis cannot provide information regarding the wear or lifetime of the sstem. Procedure Preparation Step 1: change the position of the sstem. Step 2: control of the distances between the forces and comparison with the maimum distances allowed. Calculation Step 3: calculation of the necessar driving force. Step 4: calculation of the maimum load on the in - and - direction. Result Step 5: control of the maimum load on the, the sliding element where the biggest load occurs (step 4). Step 6: Establishing the maimum speed allowed for the calculated loads of step 4. Evaluation T E C H N I C A L

6 LINEAR MOTION Setting the Clearance drlin T are delivered read for mounting. The setting of the bearing clearance is carried out at the factor. The pre-adjustment is carried out on the basis of the displacement force per slide. If ou have special requirements please indicate in our order whether particularl limited or etended bearing pla is to be preset. If required the bearing pla of the drlin T slides can be readjusted. This should alwas take place without an additional load: 1. First loosen the lock nuts. 2. The guide pla for the 3 bearing points can then be readjusted with an Allen ke. In doing so please check the effectiveness via the sliding forces. 3. After ou have adjusted all 3 bearing levels the pla on the guide inserts should be checked once again. 4. There is a danger that the ecessive reduction of the clearance seies the slide elements and that the pla cannot be re-set simpl b loosening the Allen screws. The sliding elements are then loosened again b pressing the reset button on the opposite side. Please use a 3mm pin for models 25 and 30 and a 2.5mm pin for the models 15 and 20 to press strongl against the readjusting spring. You must alread have loosened the respective heagon socket screws. ➊ ➋ ➌ ➍ T E C H N I C A L Reset Button

7 T E C H N I C A L LINEAR MOTION Fitting Instructions The drlin T slide guide rail alwas requires a small clearance between the slide and rail. The connecting surface which is screwed to the slide must be ver flat, otherwise there is a danger that the slide will be subjected to tension. When two parallel rails are used one slide must be fitted as a fied bearing and one slide must be fitted as a floating bearing. When ou order we will therefore ask ou to describe the fitting situation, preferabl on the special order form. drlin T slide rail guides are supplied in assembled and pre-set conditions. If necessar the slides can be removed for better mounting of the rails. Please note that the side with endcover which has the part number on the bottom right-hand edge must be first pushed onto the rail. The setting of the bearing clearance is also to adjust the slide eactl to match the slide rail. Both the rails and the plastic cover of the slide are marked to avoid accidentl turning the slide Marked around when mounting.

8 LINEAR MOTION The Sliding Inserts The Iglidur J material with hard anodised aluminium achieved the best results b far in our tests. Comprehensive investigations showed that for the relevant loads of linear guides the slide made of Iglidur J are the most suitable. The offer the greatest wear resistance and at the same time guarantee ver favourable abrasion values. Compared to slide partners made of hardened steel it even proved possible to further improve the abrasion resistance b a factor of 3 using gliding partners made of hard anodised aluminium. Special Characteristics of Iglidur J ver low abrasion values during dr operation ecellent wear resistance maintenance-free operation vibration damping ver low moisture absorption Operating Temperatures Iglidur J slide can be used under temperatures of -40 to a maimum of +90 C. The ecellent heat conduction of the aluminium rail means that it is onl necessar to take note of the generated friction heat during ver high speeds for prolonged periods of time. Chemical Resistance Iglidur J is to weak acids, diluted alkalis, as well as fuels and all tpes of lubricants. The ver low moisture absorption allows them to be used in wet or moist environments. The resistance to alkalis allows them to be used in applications in which plants or parts of them have to be frequentl cleaned.
