SKF to Supply Railway Wheelset Bearings to Morocco’s National Operator

SKF has won a three-year contract to supply railway wheelset bearings to the Moroccan national rail operator, Office Nationale des Chemins de Fer du Maroc (ONCF)

The Moroccan rail operator, ONCF has placed an order with SKF for the delivery of 15,000 railway wheelset bearings over a period of three years for both passenger and freight rolling stock. SKF was chosen because it was the only supplier who could meet the client’s strict technical specifications while being in a position to deliver ready-certified railway bearings on a lead time of just three months.

Wheelset Bearings

The units being delivered to ONCF include SKF’s spherical roller bearings (SRBs) which are typically applied as sets of two double-row bearings in a configuration where the two rows of rollers share a common spherically profiled raceway in the outer ring and the two inner raceways are inclined at an angle to the bearing axis. Single spherical roller bearings are also deployed in axleboxes to gain greater design flexibility. In both cases, these bearing configurations are highly tolerant of misalignment and shaft deflection.

Railway Certified

SKF railway certified SRBs have a higher load carrying capacity compared with that of competing products, which is of particular benefit to heavy freight carrying rolling stock applications. Moreover, the new cage design of these bearings ensures higher reliability and longer service life, as well as greater tolerance of the high temperatures and harsh climatic conditions that are typical on this continent.

Africa’s Rail Development

Rail development across Africa is gathering pace; in 2015, ONCF became the first rail operator in Africa to take delivery of high-speed trainsets, which will be deployed on its Tanger-Casablanca line.

Mahdi Sebti, the Paris based Managing Director of SKF’s North African operations said:

“SKF has longstanding experience of railway engineering and the company’s bearings are in use throughout the world, delivering high reliability and long service life under all operating conditions. This new contract with ONCF demonstrates our ability to meet the toughest of specifications while also being ready to react to an exceptionally tight deadline.”

Innovative and Reliable Bearing, Condition Monitoring and Lubrication Solutions for Rail Around the World

SKF's engineering knowledge combined with years of practical experience, rigorous testing, quality control and validation, is the solid base on which reliable solutions to the railway industry are developed and offered. SKF offers a wide variety of advanced product solutions for a broad range of railway rolling stock, including high-speed and very high-speed trains, diesel and electric locomotives, diesel and electric multiple units, freight cars and mass transit vehicles such as metro cars and tram cars.

Axleboxes and Wheelset Bearings

Designed for reliability and safety, SKF offers a wide choice of wheelset bearing solutions for all kinds of railway rolling stock. SKF focuses on reducing friction which lowers both energy consumption and operating temperature. This leads to longer grease life and hence extended maintenance intervals. For example, SKF Passenger bearing 1.7 M km maintenance free axle box bearing is world leading, without compromising safety. Axleboxes are the link between the rotating wheelset and the quasi-static frame of the bogie or running gear of a railway vehicle. Axleboxes and Wheelset bearings/units have always been a vital component in the reliability and safety of railway rolling stock. Through comprehensive fatigue testing capabilities, SKF ensures reliability while balancing weight and cost requirements. Millions of SKF axleboxes are in service throughout the world. SKF has extensive experience in finding robust solutions for freight wheelset applications, running in every climate, from moderate Mediterranean to tropical desert to sub-zero wilderness. Innovative sealing technology provides longer grease life and lower friction enabling extended maintenance intervals. SKF is certified according to all relevant industry norms.

Drive System Bearings

With technical risk assessment capabilities and equipped with advanced modelling and calculation tools, SKF drive system competence center with experienced engineers are dedicated to finding the optimal solution for each customer’s unique application conditions. SKF bearings for drive systems are designed to cope with variations in speed, temperature, load, vibration, shocks and electrical system properties. Additionally, traction motor bearing units are designed to handle in-application contamination and humidity. [gallery ids="9322,9323,9324"]

Lubrication Systems for Rail

Wheel and track conditions have a significant impact on rail productivity, and maintenance needs in this area dramatically affects the life-cycle cost of both vehicle and track. Thousands of trains around the world operate more reliably and efficiently thanks to SKF and Lincoln automatic lubrication systems. By delivering precise amounts of lubricant directly to the wheel/rail interface, automatic lubrication systems provide significant benefits in terms of wear, energy and noise reduction.

Condition Monitoring for Rail

Reaching the rail industry’s goals of increased maintenance intervals and maintenance-free targets of more than one and a half million kilometres requires transitioning from time-based maintenance schedules to condition-based maintenance. This ensures that vehicles are only taken out of service for maintenance when it’s actually necessary. SKF bogie condition monitoring solutions use condition detection systems and sophisticated data processing algorithms to detect incipient damage. This allows sufficient time for repairs before significant mechanical failures can develop, helping to increase reliability and safety, while contributing to reduced maintenance costs, life cycle costs and total cost of ownership. With over a century of expertise in rotating machinery, SKF’s technological knowledge is deep, and our proprietary early warning algorithms and our diagnostic expertise are key advantages of our condition monitoring solutions. From components to full systems, SKF is a proven technology supplier with full bogie monitoring solutions ready to go, as well as customized technology options. [gallery ids="9319,9320,9321"]
