SKF Ball Bearing Unit Boosts Engine Efficiency
SKF has developed a ball bearing unit to improve turbocharger performance in a wide range of applications in automotive, marine, energy, construction and agricultural sectors. The Turbocharger ball bearing unit is said to cut fuel consumption by up to two per cent and reduce CO2 emissions by three per cent, in comparison with traditional plain bearing systems. With a minimum number of components, the compact ball bearing unit is said to be easy to assemble in order to reduce installation time and costs.
This customised, precision product uses a double-row ball bearing design to minimise frictional losses and ensure higher running accuracy than conventional plain bearing units, as well as reduce turbo lag at low speeds, according to SKF. The unit incorporates wear-resistant ceramic rolling elements that can function at high temperatures and under poor lubrication conditions to generate lower centrifugal loads at high speeds, while also being able to withstand high thrust loads to maximise pressure boost.
In addition, the Turbocharger ball bearing unit uses advanced technologies and materials, such as aerospace-standard steel and a reinforced steel and polymer cage design for optimum durability. This design also minimises noise and allows integrated damper and anti-rotation features to be added.
