Končar’s Latest Trains to be Equipped with SKF Bogie Components

Croatian rolling stock producer, Končar KEV has finalised an agreement with SKF for the supply of bogie components for its latest low-floor electric and diesel-electric multiple unit trains.

SKF has been involved with Končar KEV and the development of the latter’s new electric multiple units and diesel-electric multiple units (EMUs and DMUs) since 2008. Being a relative newcomer in the EMU and DMU field, the reputable locomotive producer chose SKF as a technically competent and reliable supplier to support them during the challenging development quest.

SKF Bogie Components

Končar’s designers, along with SKF’s experts, were able to draw on SKF’s extensive experience as a major supplier to the global rail industry and a contract was subsequently signed for the supply of SKF link arm axleboxes, sensorised tapered roller bearing units (fitted with Gerken earth return devices), bearing temperature monitoring systems and speed sensors for the wheel slide protection systems.

Fully Integrated Solutions

In addition to benefiting from the valuable technical assistance provided by SKF, Končar could also simplify parts of its supply chain thanks to the complete package being supplied from one supplier. At the same time, fully integrated solutions such as the temperature sensor-equipped bearing units saves time and reduce the complexity of the bearing condition monitoring system.

Končar’s Latest EMUs and DMUs

The architecture of the EMU and DMU vehicles comprises five and four bogies respectively. During the development of these trains, SKF was initially involved in the supply of components for the prototype (built in 2009) and for two additional units built shortly thereafter. In 2014, SKF got an order to equip the remaining series totalling 20 EMU and 1 DMU unit. These are all assembled and commissioned in Croatia and are all in service since 2015.

The first series built Končar KEV Class 6112 four-car EMU was delivered to the Croatian national passenger operator HŽ PP on March 30, 2015 and the first Končar KEV Class 7023 three-car DMU entered service for HŽ PP on February 15, 2016.

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"]
