4 T RACE s range of linear bearings are setting new standards due to their innovative design and technical concepts. The family MONORACE, based on different C-shaped rails with a wide range of sliders, is offering unique linear solutions for all kinds of automation applications for many industries. T RACE s system with roller sliders and internal raceways, offer the markets highest performing system, along with being size wise the most compact system. The rails of MRG, MR and ML series are high precision cold drawn profiles, made from steel alloy that with our patented T RACE NOX thermo-chemical hardening process provide a very hard surface for high wear resistance, along with and at the same time a good protection against corrosion, even in critical environments. HIGH PERFORMANCE The new rails MRG series rails are the evolution of the consolidated MR series. The new rails have a number of improvements related to the contact geometries, new materials for increased strength and depth of hardening - T RACE-NOX 2.0 last generation hardening treatments, showing our commitment to continuous technological improvement of T RACE products. The new MRG43 is companied with a new version MRG46 with increased thicknesses of the flanges to achieve a more rigid rail for critical application, where the rail becomes a self-supporting part of the structure. The MRG and MR rails allow combinations of different sliders to obtain self-aligning systems based on pairs of rails. Such self-aligning system is able to compensate for surface assembly inaccuracies on longitudinal and transverse plane, like non precise carpentry, aluminum structures or bent sheet metal structures, hereby avoiding costly processing / machining to achieve precise parallel rail installation. The internal raceways with protected roller wheels, along with lateral seals and strong wipers, incorporating preoiled felts makes the MONORACE linear system very suitable for even harsh ambients, - dust, humidity etc. The rollers of large diameter are rarely sensitive to impurities entering the linear system. GENERAL CHARACTERISTICS 9 STANDARD The ML series rail represents a simplified version of the MR series with similar dimensions. The thinner C shaped rails have the concave inner raceways in which slide rollers of single row bearing with shields and inner ball cage made in metal. The carriages in various versions are equipped with wipers with lubricating felt. The ML series does not provide self-aligning features COST EFFECTIVE LAN rails are made from sheet steel and shaped by high precision, ultra-smooth forming rollers. They are then case hardened using our revolutionary TRACE-NOX nitriding and black oxidising process to ensure an extended lifetime and excellent corrosion resistance. The slider bodies are cataphoretically blackened for maximum corrosion resistance. The rollers are made from core tempered and precision ground, bearing grade steel. The ball bearings are lubricated for life with wide temperature range bearing grease and protected by 2Z rated metal shields. Robust elastomer raceway wipers are fitted at both ends of the slider to protect the rollers and keep the raceways clean. The wipers incorporate oil-impregnated felt pads to keep the points of contact between raceway and roller properly lubricated, for the lifetime of the rail. Wipers are held in place by a simple clip and can be removed and replaced easily. INOX LAX series rails and PAX series sliders are constructed entirely of stainless steel and are a simple and functional solution for applications that require high corrosion resistance,. The rails and sliders bodies are made from 300 Series stainless with rollers made from 440C. These are particularly suitable for food processing, pharmaceutical, and medical applications or in difficult environments such as marine environments where there is exposure to highly corrosive agents. The slider is equipped with 3 rollers. The middle roller is eccentric and is used to adjust the slider preload. The sliders are easily washable for applications subject to frequent cleaning and do not release particles into the environment and are particularly suitable for clean rooms. They are available in two sections: 26 and 40 mm. The roller linear MODULAR system FLEXRACE offers the maximum flexibility configuration due to the original shape of the guide FXRG, basic component of the system, shaped with 3 raceways arranged at 90 to each other on which can slide the rollers R..G 43 series indifferently on each of the three raceways. The using of the single guide or two or more parallel guides gives rise to a number of combinations capable of satisfying each specific need for linear motion and offering exceptional ability to self-alignment. Like the MONORACE s MR & ML rails, FXRG rail is constructed in high strength steel hardened with the last generation T RACE NOX 2.0 hardening treatments, for a further improvement of the performance and durability. The ball cage linear slide HIGH LOAD of SF series offers a very high load capacity in a compact size. They are built from the base of the rail ML series with one or more sliders that move through the interposition of one or more robust ball cages with large diameter balls. Like the MONORACE rails are made by the same production process and hardened with thermochemical process patented T RACE NOX 1.0. They are suitable for horizontal movements with high loads in all directions and for movements where the stroke available is completely used.

9 ROLLER POSITIONING TECHNICAL FEATURES Sliders are available with either 3 or 5 rollers. For the 3 roller version, the first and third roller are fixed concentric rollers that run on the same raceway. The second roller is eccentric and runs on the opposite raceway. The eccentric feature is used to adjust the slider preload in the rail. For the 5 roller version, the two lateral and the central roller are fixed, and run on the same raceway. The second and fourth roller are eccentric and run on the opposite raceway. The eccentric feature is used to adjust the slider preload in the rail. Because one raceway contacts more rollers than the other raceway, the sliders have a preferred loading direction. The slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading. Care during assembly is required to ensure the maximum load capacity of the system is achieved. 3-ROLLER SLIDER 14 5-ROLLER SLIDER RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the rail s raceways. The guiding rollers RCV. (concentric) REV. (eccentric) are in contact with the raceways by 2 contact-points, hereby creating well constrained rollers on the raceway, both in radial and axial direction. The Floating Rollers RCP. (concentric) REP. (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders. The roller can also rotate a little. The Flat full Floating Rollers RCU. (concentric) REU. (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation. Being completely cylindrical It allows axial travel to be wider than R.P-version, but being free from lateral shoulders, it can run out of the rail or against the bottom rail,when exceeding the nominal floating capacity. The Roller can also rotate a little.

These sliders are able to carry full radial load, while floating and rotating a bit, without affecting the preload or the smooth running quality, to eliminate eventual binding problems, typical for recirculating ball-bearing sliders. By utilizing all full flat floating rollers RU., RUS sliders are obtained. These sliders are able to carry full radial load, while floating and rotating a bit, without affecting the preload or the smooth running quality, too eliminating eventual binding problems, typical for recirculating ball-bearing sliders. Extra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfaces. Being completely cylindrical, free from lateral shoulders, it can run out of the rail or against the bottom rail, when exceeding the nominal floating capacity. The slider can too rotate a bit. By mixing guiding and floating rollers RA., RAS. sliders are obtained. These sliders are able to carry full radial load, while rotating a bit, without affecting the preload or the smooth running quality, meanwhile allowing for precise movement. These sliders also retain the ability to guide the payload as it travels. Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces, that cause traditional bearings to bind. New RAG/RAGS sliders with MRG43/46 rails offer greater rotation capacity, compared with RA sliders with MR43 rails. TECHNICAL FEATURES 15

13 MRG RAILS TECHNICAL FEATURES The MRG Series Rails are available with two types of mounting holes: MRG.. L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail. MRG.. S with countersunk mounting holes for UNI-standard ISO5933 common screws. The rail has a C shaped cross-section with interior, convex raceways. The convex raceways are polished for smooth, low noise movement. The interior raceways are protected from accidental bumps and other damages, that might ruin the raceway surface. The shape also protects the rollers from similar types of damage. MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 2.0 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance. This treatment is not a plating which can flake off but instead penetrates and alters the material surface. The result is a very hard and durable, corrosion resistance linear rail, that is black in color, due to the micro impregnation of oil and antioxidants.

21 ROLLERS FOR MRG RAILS The precision rollers R..G series for MRG rails have double-row ball-bearings to provide high-capacities, both in radial and axial direction. They are available in the guiding version R.VG series, with two contact points on the V-shaped roller raceway. Compared to rollers for MR rails, these new rollers have Gothic shaped raceways for improved performance. The Floating roller versions have one contact plane, the axial floating of the R.PG rollers are limited by the two lateral shoulders. The Extra floating rollers series R.UG have completely flat outer ring, without lateral support. The rollers are equipped with 2RS seals, nitrile rubber with reinforced metal core. The rollers are lubricated for life with lithium based grease. Inner and outer bearing rings are made of core hardened bearing steel, ground to DIN620 precision classes. GUIDING R.V..
