One of the important steps in creating a new axle unit with roller bearings is conducting field tests toconfirm reliability.The current design of axle unit with two cylindrical roller bearings the great landing is unreliable andcostly maintenance.Analysis of international experience of design and operation of the axle unit bearings suggests thatone way to improve the reliability Books roller bearings may be made of cassette type. Use of such bearings in the axle boxes of cars will increase the reliability of the axle unit, switch to the other system maintenancethat will reduce the cost of technical maintenance and repair, saving considerable material and humanresources, increase the level of traffic safety stitching.The comparative performance test cars about two-row tapered rudovannyh-cassette-type bearings inthe test route Ukrzaliznitsi Rokovata-Uzhgorod in real exploitation in the railway network in Ukraine.During the extended operational test failures are not documented cases of axle assemblies with double-rowtapered roller bearings, which have caused a non-permissible heating bux and uncoupling from the wagontrain. According to the test results determined for the reliability and durability of the axle boxes.On results the tests reliability and longevity of axle bearing boxes indexes are certain.The analysis of the performance testing dual bearings, cassette-type SBU in Buchs freight cars.
