Instructions of assembly Selection and formation of pairs of bearings consideration of radial clearance to make respectively followings regulations: The difference of radial clearances of two bearings mounted on same axle must not exceed 0.015 mm, with own inner ring. Using standard inner this difference may not exceed 0.01 mm. In case of measuring the radial clearance directly on the axle the difference may not exceed 0.02 mm. Bearing inner rings carry circumferential load, therefore they are press-fitted: axle journal p6, housing H7. Cylindrical roller bearings do not, however, compensate misalignment between axle and bogie frame. Therefore misalignment must be corrected by angular freedom of the housing. 5. Clearances of bearings for axleboxes wagons and locomotives Clearances before Radial Radial Bearing (set) Group mounting clearance clearances [x 0.001mm] reduction after mouting radial axial (set) [x 0.001mm] [x 0.001mm] WJ+WJP130/240 TNC4 C4 125...165 300...780 30...64 61...135 WJ+WJP130/240 TNC4 C4 145...190 660...1190 35...75 70...155 5
6. Methods of measuring and checking The dimensional checking and measurement radial and axial clearances of bearings are according ISO/TR 9274 and ISO 5753. The radial clearance for bearings according 1A risk class is checked with passive control devices. Parameter Bore diameter (d) Outside diameter (D) Width (B) Radial clearance Axial clearance 7.

Axial and radial loads These bearings are particulary suitable for supporting high radial loads with special internal constructions and polyamide cages. The dimensioning is usually based on a calculated operating life of more than 3 million kilometers. a) Radial loads: Static axle load : 160 kn; P-equivalent bearing load, kn; P = 0.5 x f 0 x f 1 x G for two bearing axleboxes; P= 104 kn were: f o - factor to the variation in payload and can be set at f o = 0.9 to 1, for passenger rolling stock; f 1 - factor of summarises the influence of the radial and axial dynamic loads, the values being determined by running speed, track conditions, wheel suspension and unsprung mass. f 1 = 1.2 to 1.4 for passenger rolling stock; G - maximum static axlebox load in kn; G = 80 kn; b) Axial loads: For WJ+WJP130/240: F ap - maximum permissible axial load, kn; F ap = 11.8 kn for a constant axial load, for short periods the values may be multiplied by 2; F a max. - axial limiting load, kn; F a max. =69.1 kn For WJ+WJP130/240: F ap - maximum permissible axial load, kn; F ap = 11.2 kn for a constant axial load, for short periods the values may be multiplied by 2; F a max. - axial limiting load, kn; F a max. =69.1 kn 9. Laboratory test Test is named Accelerated Life Test. The results are evaluated according to 90% criterion of reliability. Test schedule is applied to a lot of 30 brgs., from wich are tested 20 brgs. The test is running untill 8/10/20 fatique failures (pitting on raceways) occurs, and the results are statistical estimated with the maximum-likelihood method. Test parameters (speed, lubrication, load) are calculated theoretically for each type of brg. The rigs can test the performance and durability of two bearings simultaneously under identical conditions. The radial load can be applied by hydraulic pistons. In our laboratory make followings types tests: - tests for confirmation of basic dynamic load rating or rating life estimation for bearings from currently manufacture; - tests of rating life required by customers; 6
- tests on research problems ( for verification teoreticaly aspects with regard to design bearings); 10. Dismounting of the inner ring from the shaft Dismounting the inner ring of bearing make to heating about 60 sec used induction heaters or with conduction heating. For this particular bearing and application non-adjustable induction heaters are designed. They are normally used to dismount inner rings of multi-row cylindrical roller bearings. 11. Instrumentation and tools for mounting and dismounting of the bearings - heating equipment; - extraction devices; - high - pressure pumps for hydraulic mounting methods; - fitting devices; - multi-plate presses; 12. Preservation The preservation of bearings make according SF 24006/2008 using of Castrol Rustilo DWX33 solvent with quaranty period protection for two years. A high quality soft film rust preventive, on evaporation of the solvent, leaves a powerful protective film. Before of preservation the bearings must to be washed with Shell Callina 2402, petroleum solvent. 13.
