ABEG® Xforce – NO STRESS UNDER HEAVY LOADS A long service life, high strength, guaranteed safety, dependable sealing technology, favourable price and short delivery times – the ABEG® Xforce series bundles all of these vital specifications for bearings used in heavy duty applications. These stringent criteria were satisfied by modifying the proven bearing technology with special seals for tough environmental conditions and special greasing with extreme pressure (EP) additives. Service life and comparison tests with selected types reveal that bearings with Xforce specifications triple the service...

The Lubricant Makes the Difference Conventional grease is only good enough for standard performance; although solid lubricants produce better greasing results, they are very costly. However, EP (extreme pressure) additives on the other hand boost performance considerably in an economic way. Quadrupling the service lives is quickly and economically realisable. 700 000 Premium Standard Supra Xforce Optimal Protection Tough conditions require good seals. Bearings of the Xforce series are equipped with double-lip seals running in grooves. They ensure outstanding seal performance and reliably prevent...

Load Rating and Loads In addition to practical service life tests on the 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. A complete lubrication with standard grease (effectively separating the metallic surfaces between balls and the bearing raceway) cannot be successfully achieved at low rpm in particular. The reason for this is that the viscosity...

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, when bearings are used in high or low temperature applications for instance, it is necessary to use the extended service life calculation. 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. bearing type table) K = Viscosity ratio (cf. diagrams 1, 2 and 3)...

series Service Life Coefficient a. Viscosity Ratio k 50 The viscosity ratio k indicates to what extent adequate lubrication is provided by the selected oil. If k > 1, complete lubrication is achieved at the operating temperature, and the oil is suitable for the application. If k < 1, it is recommended that an oil with EP additives is selected. If k < 0,4, this can cause marginal lubrication and thus corrosion of the sliding surfaces. It is essential that oil with EP additives or solid grease is used in such cases.
