IBC Wälzlager develops energy-efficient deep groove ball bearings (E)
Not only are energy costs rising, so is the demand for reduced noise emissions. The answer: energy-efficient e-bearings. Indirect energy consumption in electric deep groove ball bearings can be reduced by various measures. But which adjusting screws are necessary and does it always have to be everything?
First, friction. It can be significantly reduced by the new E-grooved ball bearings from IBC Wälzlager - by as much as 35 percent compared to standard designs. And not only that, the noise level is also reduced by 30 percent compared to conventional deep groove ball bearings of the same size.
Second, lubrication. Since many deep groove ball bearings with cover disks and seals are lubricated for life and the grease type and quantity make a decisive contribution to heat generation, special quality is required here. Therefore, IBC uses a smooth-running, low-noise grease with optimized grease quantity for E-roller bearings. This results in an optimum ratio between heat generation and grease reservoir, i.e. grease service life. A positive side effect: the low operating temperature decisively extends the grease service life, and thus the service life of the bearing.
Third, the seal design. Normally, the seal lip contacts the inner ring and thus has some friction during operation. In the new E-deep groove ball bearings, the inner ring has a groove that protrudes into the seal and provides highly effective non-contact sealing against external influences via a labyrinth - thus eliminating the friction factor. There is also potential for optimization in the cage design, for example through improved sheet steel cages. In addition, polyamide cages produced by injection molding can keep friction and operating temperature even lower.
Fourth, the surface finish of the raceway. Here, too, the E-bearings can score points. This is because their roughness values are 25 percent lower than those of standard bearings.
If the bearing is to be further optimized in addition to these four points, two measures are available. Firstly, the raceways can be coated with the proven ATCoat coating to reduce friction and extend service life. Secondly, the use of ceramic balls, in addition to current insulation, can increase the speed by 30 percent - and at the same time increase service life. Ultimately, all these optimization options must be viewed as a construction kit. Not every application requires all solutions. Rather, users must decide individually what is necessary in a specific case. After all, a measure is only effective if it is also economically optimized.
In October 2018 the gates of the Motek fair, the world’s leading event in the fields of production and assembly automation, feed technology and material flow, streamlining through handling technology, and industrial handling, opened again.
The two Solms-based companies, IBC Wälzlager GmbH and ATC Armoloy Technology Coating GmbH
& Co.KG, can look back on a successful EMO 2017 in Hanover. Everything revolved around precision at the biggest machine tool trade fair in the world, held at the end of September. Once again the two companies had a chance to show their know-how and ability for innovation.
With precision to the stars
At IBC Wälzlager everything revolves around precision. Now the advanced technology from Solms is being put to use in the Very Large Telescope (VLT), the largest celestial eye in the world, located in the middle of the Chilean desert.
The Atacama Desert in Chile is the driest place in the world and is also the location to the Paranal Observatory. From there it is possible to investigate heavenly bodies that are well outside our solar system. IBC Wälzlager GmbH from central Hessen provides the precision that is required to take photographs with an angular resolution of a thousandth of an arc second.
The comprehensive range of products from IBC has many solutions for the sector of drive technology in the form of linear guides. In roller-guided systems combinations of sealed carriers with specially profiled guide rails with locating and floating bearings that are easy to install are offered. The guide rails that are matched at their ends can be obtained in almost any desired length.
The W3+ FAIR once again opened its doors at the Rittal Arena in Wetzlar on 21st and 22nd February 2017, this being an interdisciplinary trade show for the fields of optics, electronics and mechanical engineering. IBC Wälzlager GmbH also took advantage of this opportunity, under the trade show motto of "faster, longer, higher ... curious?" to inform comprehensively in person at that location about its new items and innovations and to demonstrate in a most impressive way how important it is to have a presence in the marketplace nowadays and to work in a future-oriented way.
