Bearings cut energy use by 30%
SKF has developed a new family of bearings that reduce energy consumption by at least 30% compared to standard ISO products.
SKF has developed a new family of bearings that reduce energy consumption by at least 30% compared to standard ISO products This new bearing family comprises the two bearing types that are the most used bearings in the world, deep groove ball bearings and tapered roller bearings

SKF launches big range of parts for machine tools
A complete package of products, aimed specifically at machine tool builders and users, has been unveiled by SKF Engineering Products Limited.
"This new family of bearings is the result of a focused effort from the SKF organisations to develop a new bearing family that while maintaining the service life and load carrying capacity of standard ISO bearings, will substantially reduce the energy consumption", says Tom Johnstone, President and CEO of SKF.
"Starting with the most used bearings in the world we ensure that our solution can be used in most machines in most industries around the world".
"That way we provide the possibility of reducing the world's energy consumption and also reducing customer's energy costs", Johnstone continued.

Why bearings shouldn't cause paper mill downtime
Paper machines are one of the best examples of the need for optimised bearing solutions, based on the correct product for the given operating conditions.
Why maintenance should be proactive
50% of all maintenance is unnecessary, according to SKF's Gerald Rolfe, who argues the case for planned maintenance strategies.
Manufacturing will start in the second half of 2007.
The demonstration of the potential of these bearings on the reduction of energy consumption of machinery is supported by the European Commission's Life-Environment programme 2006.
This programme supports new methods and techniques for dealing with a wide range of environmental problems.
SKF's energy efficient tapered roller bearing will deliver energy savings on average of at least 30% and will initially target industrial segments where applications exceed 1 MW power consumption.
Such applications are in railway and transmissions in heavy industry, ships, wind energy, conveyors, and extruders.
The initial size range will be 200 - 600 mm outside diameter and the first applications are expected to be in wind turbines.
As an example of the potential of these bearings consider all wind turbines operating in the world at the end of 2006.
If all bearings in the gearbox of all these turbines could be replaced by SKF energy efficient tapered roller bearings they would generate an estimated extra 770 million kWh per year.
That is equivalent to the total energy consumption of 1 million Swedish households for one month.
The technical improvements that deliver the energy savings are design-related; surface topography, raceway profiles and geometry, together with a special polymer cage and an optimised set of rollers.
The optimised roller set means a lighter bearing which itself is more energy efficient because it takes less power to move the rolling elements.
It also lowers inertia of the moving parts, reducing the chance of skidding and smearing, which would otherwise affect performance and service life.
SKF's energy efficient deep groove ball bearing will deliver energy savings of at least 30% in most applications.
Initially the focus will be on lightly loaded applications and the first applications will be industrial electrical motors driving machinery in many segments.
Production will initially cover the smaller diameter sized series. Request a free brochure from SKF UK ...
