Product list of Railway Bearings
Railway Axle Bearings
Axle bearings: cuscinetti a rulli conici, tapered roller bearing boxes, cuscinetti a rulli cilindrici, cuscinetti orientabili a rulli. Railway axle bearings can be subjected to high shocks and loads. Mounting space is also limited, so in many cases compact, double-row bearings with high load ratings are used.
Railway Axle Box Bearing
Axlebox bearings should have a large load carrying capacity, be able to resist shock vibration, and must have a high life expectancy, safety and reliability, smaller size and quality. Locomotive bearings often use non-standard series of bearings and special bearing technical conditions, commonly used rolling bearings are cylindrical roller bearings, spherical roller bearings and tapered roller bearings three types.
Traction engine bearings
Drive systems for railway applications, such as gearboxes and traction motors, must be robust, reliable, cost-effective, and require low maintenance. This requires specific bearings and bearing units.
Our traction motor bearings are based on a compact and space-saving design, reducing maintenance requirements and extending service intervals. In turn, you can enjoy lower life cycle costs. Main traction engine bearing types: cuscinetti a rulli cilindrici, cuscinetti a sfera
Train Transmission bearings
Gearbox bearings, supporting large and small gears in rolling stock gearboxes, are ideal for high and low speed applications. Bearings for small gear shafts offer a whole new level of value through greater reliability and reduced specialist maintenance requirements. Bearings for large gear shafts offer even greater reliability and the standard product line-up has been extended to offer a larger range of sizes to meet different customer requirements.

Products of Railway Bearings
Cuscinetto a rulli conici
Tapered roller bearings are uniquely designed to manage thrust and radial loads. Comprising a ‘tapered cup’ and a ‘tapered cone’, this design is one of the most basic and common styles in the bearing industry.
Cuscinetto a rulli cilindrici
Cylindrical roller bearings use cylindrical rollers as rolling elements, which have high load capacity. The roller is guided by the rib of the inner or outer ring.he inner ring and the outer ring can be separated to facilitate assembly.
Cuscinetto a rulli sferici
Spherical roller bearings, both open and sealed, are designed for industrial applications with higher fatigue strength, increased wear resistance and tighter shock and acceleration protection to handle the harshest environments

FAQ
A causa del loro design interno, I cuscinetti a sfere di solito non possono essere smontati fino al livello del componente; dunque, di solito non possono essere rinnovati.
High speed railway bearings
- Bearings operating at speeds above 200km/h, requiring bearings with high load carrying capacity and safety performance.
- As the double-row tapered roller bearings have a better sealing structure and the clearance has been adjusted before installation, these bearings are mainly used for high speed railway bearings.
Locomotive bearings
- Railway locomotive bearings vehicle axle system due to the use of different conditions and the use of different structures. Locomotive passenger cars have axle boxes, bearings through the axle box and bogie connected. Cylindrical roller bearings are generally used.
Freight car bearings
- Wheel pair bearings generally use cylindrical roller bearings.
Underground bearings
- Generally double row cylindrical roller bearings with sealing devices on both sides or two pairs of single row cylindrical roller bearings with sealing devices on one side. The direction has been pre-fitted with grease.
Utilizzare anelli di supporto particolarmente stabili dal punto di vista termico, maggiore gioco interno (C4), lubrificanti appositamente selezionati che non si decompongono alle alte temperature, e flinger in zinco anodizzato. Esistono due versioni base dei nostri cuscinetti per alte temperature. Il suffisso “C4HR5” rappresenta il cuscinetto in grado di resistere a 400°F, e il suffisso “C4HR23” rappresenta il cuscinetto in grado di resistere a 450°F.
Per applicazioni critiche come la lavorazione della cellulosa e della carta, stampa e confezionamento, lo strappo del materiale può causare costosi tempi di fermo dovuti a coppia e vibrazioni eccessive.
