Kharkov Bearing Plant (HARP) has successfully finished endurance testing of TBU HARP 1520 (150х250) cartridge bearing for railcars of increased lifting capacity. Endurance testing was made at the HARP Test Center, created by the United Engineering Center and UKTBPP and certified by the Government Accreditation Office of Ukraine.
“According to the results of endurance testing, TBU HARP 1520 (150х250) bearings have shown that they meet the highest world standards on reliability, durability, as well as on energy efficiency”, said Eduard Simson, Director on R&D Centre of the UPEC Industrial Group.
In confirmation of quality, there was issued a certificate of conformity “UkrSEPRO” and TBU HARP 1520 (150х250) bearings are launching into manufacturing in accordance with the established procedure.
HARP developed series of innovative closed-type cassette bearing units for the 1520 gauge, which includes cylindrical bearing unit CRU DUPLEX for axle-boxes of freight and passenger cars, double-row bearing unit CRU HARP for axle-box units of locomotives, cylindrical bearing unit of closed-type CRB HARP for traction electric motors of locomotives, and TBU 1520 for axle-boxes of freight cars for 23,5 and 25 ton-force. Thanks to the implemented technical solutions, HARP bearing units of cassette type withstand a wide range of outer temperatures from –60°С up to +120°С, and can increase safety of movement and significantly reduce exploitation costs.
