Rolling and sliding bearing solutions

Rolling and plain bearing solutions, straight and direct drive technology, as well as mechanical and electrical components that improve efficiency, save energy and achieve high performance and reliability are the focus of the Schaeffler Group Industrial Division at this year's Hanover exhibition (22 , A12 booth). Robert Schullan, President of Schaeffler Group's Industrial Division, presented these highlights at the MDA roundtable press conference at the 2011 Hannover Fair. He emphasized the excellent strategy and market position of the Schaeffler Group's Industrial Division to ensure that the company can benefit from a greater increase in the global market. "With our broad product range, innovation and position in the growth market, we are able to lead the industry in the development trend - energy and energy efficiency, electromechanical and electric, to expand the market for Schaeffler Group," he said. status."

        Needle roller bearings: small and low friction
Schaeffler Group Industrial Division of the anti-friction and efficient rolling bearings is one of the key components of the industry. Rolling bearings in energy conservation efficiency, while improving the performance of machinery and equipment and competitiveness. An example of a high energy efficiency potential for rolling bearings is a needle roller bearing that continues to improve in miniaturization and reduced friction. Schaeffler Group's Industrial Division will showcase three new INA needle roller bearings at the 2011 Hannover Show: High performance and miniaturized long life D-machined needle roller bearings with double needle holder and low friction Long life machining needle roller bearings, radial section height of only 1.5 mm elongated punching outer ring needle roller bearings.

        Newly developed for the new long life D-type machining needle roller bearings steel frame is optimized by the molding method, greatly improving the bearing capacity. Based on this design, the number of needle and the effective length of the same size than other bearings have increased. Therefore, such as the new long life machine machining needle roller bearings NK 55/25-D-XL, its carrying capacity increased by 25%. This opens up new possibilities for miniaturization. This type of bearing can reach the previous NK 75/25-XL models of long life needle roller bearings to achieve the carrying capacity.

        New machined needle roller bearings with plastic double needle holder provide higher efficiency by reducing friction. Unlike the previous single long needle, it is fitted with two short needle rollers in the same cage pocket. Compared with the traditional needle roller bearings, this combination of new cage and rolling the friction generated by the torque significantly reduced. Rotors with a speed of 4000 rpm are expected to be 25 to 30 watts lower than the traditional plastic cage bearings. This means that a needle roller bearing with a double needle holder can save the energy equivalent to a bulb.
