HARP SUCCESSFULLY COMPLETED THE TBU HARP 1520 CASSETTE BEARING (150X250) LIFE TEST FOR HIGH-CAPACITY WAGONS

The Kharkov Bearing Plant (HARP) has successfully completed the life test of the TBU HARP 1520 cassette bearing (150x250) developed by the IPEC Unified Engineering Centrer (UEC) and the Ukrainian Design and Technology Bureau of the Bearing Industry (UDTBBI) intended for high-capacity innovative wagons of the 1520 gauge track space.

Endurance tests were held at the HARP Test Centre sands created by UEC and UDTBBI and certified by the National Agency for Accreditation of Ukraine.

"Based on the results of endurance testing, TBU HARP 1520 bearings (150x250) showed compliance with the highest world standards, both in reliability and wear resistance, and in energy efficiency," said Edward Simson, UPEC JSC director for research and new developments .

The test centre where the tests were carried out is a unique laboratory for conducting certification tests of railway bearings with no analogues in the post-Soviet space. Developed in the UPEC R & D Centre in conjunction with UDTBBI and leading Western companies, the original design of the stands can simulate the conditions of the bearing operation on any part of the road.

"Thus, we can test the products in real mode of the most difficult sections of railways and operating conditions. The results of successful testing of bearing assemblies enable us to talk about the highest consumer qualities of these products," says Sergei Semykin, UDTBBI Chief Designer.

Supporting the recognition of the quality, the UkrSEPRO conformity certificate was received, and the TBU HARP 1520 bearings (150x250) are being launched into manufacturing in conformity with the established procedure.

Let's recall that HARP has developed a whole series of innovative cassette-type closed bearing units for 1520 gauge track space, which includes the CRU DUPLEX cylindrical bearing assembly for axle boxes of freight and passenger cars, CRU HARP double-row bearing assembly for freight locomotive axle boxes, CRB HARP closed-type cylindrical bearing assembly for locomotive traction motors, TBU 1520 for freight car axle boxes, which today meet the innovative requirements of increased capacity and resource (8 years or 800 thousand km) in the construction and modernization of 23.5 and 25 t / s freight rolling stock. For this  year the Ukrzaliznytsia (Ukrainian Railways) has planned the production of 50 high capacity wagons.

In view of the urgency of bringing such products to the market, HARP plans to launch batch production of an innovative series of closed-type bearing assemblies for deliveries to the railway in order to meet the needs of the 1520 gauge railway car builders.

"The full cycle of research, development, production and testing of closed bearing units with an increased overhaul life of 8 years or 800 thousand kilometres for the 1520 gauge track is one of the most ambitious projects to create innovative components for a new generation of rolling stock and an unprecedented result for the post-Soviet space enterprises, which puts HARP on a par with the world's leading companies, which today offer similar products," said Edward Simson, UPEC JSC Director of Research and New Development. He also points out that due to the implemented technical solutions and know-how the HARP cassette-type bearing units withstand a wide range of ambient temperatures from -60 ° C to + 120 ° C and can improve traffic safety with significant reduction in operating costs.

Therefore, HARP has confidently entered the elite world club of manufacturers of the cassette-type higher endurance bearing units and is offering cassette-type bearing assemblies that meet the highest energy efficiency standards with the best price-quality ratio for the 1520 gauge wagons with a capacity of 23.5 and 25 t / s.
