Xspeed: bearings high speed usage
16Pages

ABEG® Xspeed – MAR ATHON RUNNING AT TOP SPEED Long service life, high rpm, guaranteed safety, low friction sealing technology, favourable price and short delivery times – these specifications have been bundled in the ABEG® Xspeed series of bearings for high speed applications. These stringent criteria were satisfied by modifying the proven bearing technology with seals for applications in high rpm ranges, and using special greases to minimise friction. The bearings satisfying Xspeed specifications succeed in boosting the actual service lives by around 50 % compared to reference values for...

The Lubricant Makes the Difference Improved running properties at high speeds go hand-in-hand with higher specifications for surface quality and the profiling of raceways. Xspeed bearings are therefore made to satisfy tolerance class P6 with higher precision and concentricity accuracy. The bearing clearance is adjusted to the high speeds by constraining the tolerance. A special highly pure, low viscosity and low noise grease with outstanding start-up properties ensures optimal operating conditions at high rpm (cf. Figure 1). Optimal Protection The self-heating of the bearing plays an...

Load Rating and Loads In addition to practical service life tests on the bearing performance test station, the increase in performance can also be demonstrated by the extended service life calculation pursuant to DIN ISO 281. The nominal service life calculation is unsuitable because it always calculates false and excessively high service life values under extreme conditions. Because of the high rpm, there is also an inevitable rise in the operating temperature of the bearing, which in turn reduces the overall service life. To compensate for this effect, Xspeed models exclusively use...

series Calculations for the extreme Series Extended service life calculations: Under ideal operating conditions, calculating the nominal service life is adequate for dimensioning a conventional bearing. However, to take real conditions into consideration with the aim of producing better results, it is necessary to use the extended service life calculation method pursuant to DIN ISO 281 Supplementary Sheet 1. This modifies the nominal service life of a bearing by using additional coefficients. a,SO = f (ec x Cu /P K) ec = Contamination coefficient (cf. Table 2) Cu = Fatigue load limit (cf....

e Service Life Coefficient aiso The viscosity ratio κ indicates to what extent adequate lubrication is provided by the selected oil. When κ > 1, complete lubrication is achieved at the operating temperature, and the oil is suitable for the ap- plication and for a product of the Xspeed series. If 0,3 κ < 1, the lubricant must be precisely selected for the specific application conditions. In this case, contact our Applications Engineering department.
