Axial bearing washers are punched, through-hardened, polished and suitable for use as shaft or housing locating washers. These washers are suitable for use where the adjacent machine part is unhardened but is sufficiently rigid and geometrically accurate.

Depending on the size, the base is either smooth or lock-beaded (stiffened). Due to the profiled base, small axial guidance forces are possible.

Needle roller bearings have a long track record as proven machine elements for the design of radially compact bearing arrangements with very high load-carrying capacity. In X-life configuration, they now have an up to 50 % longer service life.

Some designs of drawn cup needle roller bearings are closed at one end. They are thus suitable for closing off the shaft ends of bearing arrangements. This provides protection against injury by rotating shafts and protects the bearing against contamination and moisture.

Per offrire ai nostri clienti la massima trasparenza e facilitare la scelta dei prodotti più adatti alle proprie necessità, tutti i prodotti e le attrezzature specifiche per la lubrificazione sono dettagliatamente descritti e visionabili direttamente sul nostro catalogo online. In questo modo, è possibile esplorare con facilità la nostra offerta, garantendo una completa informazione sui prodotti disponibili, le loro caratteristiche tecniche e le applicazioni consigliate.

Drawn-cup roller clutches give very precise indexing, since the individual spring loading of the needle rollers ensures continuous contact between the shaft, needle rollers and ramps. They allow high indexing frequencies due to their low mass and the resulting low moment of inertia of the clamping elements. They also have a low overrunning frictional torque.

IR inner rings have a precision machined raceway. Chamfers on the end faces allow easy insertion into the bearing and prevent damage to the seal lips of the bearing. Inner rings are available with and without a lubrication hole.

Since the needle rollers are not retained by mechanical means, they are secured for transport and fitting by means of a special grease (DIN 51825–K1/2K–30). However, this does not have adequate long-term lubrication capacity. Relubrication is therefore recommended after fitting.

Axial needle roller and cage assemblies consist of plastic or metal axial cages with integrated needle rollers and have a very low axial installation height. They support high axial forces in one direction. Radial loads must be supported by separate means. Axial needle roller and cage assemblies require hardened and ground running surfaces as a raceway.

LR inner rings have a ground raceway. The end faces are turned and the edges are broken. These rings have larger tolerances than the IR rings. They are thus suitable for applications that allow larger width tolerances and less demanding requirements for axial runout.

The radial internal clearance can be influenced by the needle roller sort as well as by the shaft and housing tolerances. Needle roller and cage assemblies require a hardened and ground raceway on the shaft and in the housing.

Drawn cup needle roller bearings with open ends are supplied with a needle roller and cage assembly or a full complement needle roller set. Bearings with needle roller and cage assemblies allow higher speeds than the full complement designs.

Inner rings are made from hardened rolling bearing steel and have precision machined or ground raceways. They are used where:

I.M.T. è specializzata nel settore degli impianti di lubrificazione a Milano, offrendo soluzioni avanzate per mantenere i macchinari in condizioni ottimali. Grazie alla riduzione del coefficiente di attrito, alla diminuzione della temperatura operativa del lubrificante, alla riduzione della rumorosità delle apparecchiature e alla loro capacità di gestire carichi pesanti, garantiamo il massimo dell'efficienza e della durata per ogni tipo di macchinario.

Needle roller and cage assemblies are single or double-row units comprising cages and needle rollers. As their radial design height only corresponds with the diameter of the needle rollers, needle roller and cage assemblies can be used to realize bearings with a minimal radial design envelope. They have high load carrying capacity, are suitable for high speeds and are particularly easy to fit. If the raceways are produced to high geometrical accuracy, bearing arrangements with high runout accuracy can be achieved.

Inoltre, l'azienda milanese offre soluzioni avanzate grazie alla sua fornitura di attacchi rapidi per aria, progettati per ottimizzare le prestazioni dei vostri macchinari, garantendo un incremento significativo dell'efficienza operativa.

Axial needle roller bearings are construction units consisting of axial needle roller and cage assembles and thrust bearing washers with centering spigots. They can be combined with drawn cup needle roller bearings with open ends, drawn cup needle roller bearings with closed ends and needle roller bearings. The running surface for the needle roller and cage assembly must be hardened and ground.

Thrust bearings

Drawn-cup roller clutches can be used in various applications such as indexing clutches, back-stopping clutches and overrunning clutches. In these cases, the drawn cup roller clutch performs an overrunning or locking function.

The bearings can compensate static shaft misalignments and can therefore tolerate misalignment of the shaft relative to the housing. Aligning needle roller bearings are firmly seated in the housing bore. The bore can therefore be produced easily and economically.

Avrete la possibilità di scegliere tra un'ampia varietà di sistemi di lubrificazione, così come diverse metodologie di applicazione, in base alle specifiche esigenze dei vostri macchinari produttivi. Questo vi permetterà di trovare la soluzione più adatta per garantire la massima efficienza e durata delle vostre attrezzature.

Aligning needle roller bearings are units comprising drawn outer cups, plastic support rings with a concave inner profile, outer rings with a spherical outside surface, needle roller and cage assemblies and removable inner rings.

They are characterized by a longer rating and operating life – the result of higher dynamic load ratings than those of current standard products. If the load and design envelope are unchanged, X-life bearings have a longer rating life. Longer maintenance intervals are possible.

Grazie all'introduzione del processo di automazione per la lubrificazione dei macchinari, il rifornimento di olio o grasso sarà garantito al momento giusto, nei punti in cui è maggiormente necessario ed esattamente nella quantità esatta richiesta. Questo non solo assicura una lubrificazione adeguata ma anche minimizza l'uso di tali materiali, portando a un significativo risparmio di risorse e contribuendo positivamente all'ambiente.

Inoltre, l'azienda propone impianti di lubrificazione a Milano equipaggiati con pompe di alta qualità per la lubrificazione, progettate per ottimizzare il processo e garantire la massima affidabilità nel tempo. Questo elemento è fondamentale per assicurare una manutenzione efficace e ridurre al minimo gli interventi di riparazione, contribuendo così a mantenere alta la produttività e a limitare i tempi di fermo macchina.

In these bearings, the raceways have optimized roughness and geometrical accuracy. This gives a higher load-carrying capacity and longer service life. X-life is the premium brand that identifies particularly high-performance products under the INA and FAG brands.

Full complement drawn cup needle roller bearings with open ends have the maximum number of needle rollers and therefore offer extremely high load-carrying capacity within a very small design envelope. However, their use at high speeds is restricted.

Thanks to an improved surface quality, the load ratings of X-life needle roller bearings have been increased even further. The dynamic load rating could be increased by 13 % compared to the previous needle roller bearings. The substantially improved load ratings lead to higher-performance bearings with a longer service life, reduced lubricant load, reduced friction and lower bearing temperatures. The benefits stemming from all of these developments include greater efficiency for your applications and a much better price-to-performance ratio.

Drawn-cup roller clutches are one-way clutches comprising thin-walled, non-cut outer rings with ramps on the inside diameter, plastic cages, pressure springs and needle rollers. They can transmit torques in one direction and are radially compact. The roller clutches are available with and without bearing supports.
