SKF has unveiled a model that enables the working life of hybrid bearings to be determined

SKF has unveiled a model that enables the working life of hybrid bearings to be determined more realistically. With the development of the Generalized Bearing Life Model (GBLM), SKF customers and distributors can be sure they choose the right bearing for the right application, every time. Until now, it has been difficult for engineers to predict whether a hybrid bearing will outperform a steel one in an application, or whether the possible performance benefits that hybrid bearings enable are worth the extra investment required. The conventional equations engineers use to calculate the rating life of a bearing don’t reflect the real-world performance of hybrid designs. To address this issue, in 2012 engineers at SKF started to develop what would become GBLM. A primary version of the model was presented at Hannover Messe in 2015, but at this stage the model was not ready to perform calculations for hybrid bearings. Four additional years were needed by scientists and technicians at SKF’s facilities in the Netherlands and Austria to incorporate this feature into GBLM. Using GBLM, SKF engineers have been able to determine the real-world benefits hybrid bearings can have. In the case ...

EVGA Brings a Bunch of New PSUs to Computex 2019 picon-graphics icon arrow stem circle

EVGA introduced new power supply units in the GD, G5, G7, and P3 product lines at Computex 2019. The units cover everything from budget models to high-end products and, when that’s combined with their varying footprints, they should be able to squeeze in to a wide variety of systems.The new GD line consists of affordable models featuring 80 PLUS Gold efficiency, five years of warranty, DC-DC converters for the generation of the minor rails and a semi-modular cable design. The original manufacturer (OEM) is FSP. The GA models are made by Andyson and they are also Gold certified. Those power supplies are fully modular and use Japanese caps along with 135mm double ball-bearing fans. This is why, at 10 years, the provided warranty is double that of the GD models. The G5 units use a new Super Flower platform which is 80 PLUS Gold certified. All cables are modular and the FDB fan measures 135mm across. A semi-passive mode makes sure that the noise output is kept low under light loads, while the provided warranty is 10 years long. The G7 units are similar to their G5 counterparts, with one major difference, which is the smaller footprint. Because of the compact dimensions, a sma...
