SKF SPEEDI-SLEEVE is a well-proven solution to overcome problems with worn shafts, without having to disassemble the shaft or specify a new seal size, while offering an excellent sealing surface. The new generation of SKF SPEEDI-SLEEVE is designed to even further enhance the total sealing system performance.
To seal effectively, radial shaft seals must run against a smooth, round counterface - most often a shaft. If the shaft becomes worn, the seal will no longer be able to retain lubricant and exclude contaminants.
To repair the shaft, it is usually necessary to disassemble the machine in order to regrind the seal counterface until it is within specification again. This costly and time-consuming approach can be avoided by using SKF SPEEDI-SLEEVE. The sleeve is simply pushed into position over the damaged shaft and provides a new, excellent seal counterface in minutes.
Industrial shafts with diameters from 12 to 200 mm (0.5 to 8 in.) in a wide range of applications like:
CCB busts counterfeit ball bearing dealers gang in Broadway/Chennai – India and seized fake SKF ball bearings pegged at a value of Rs 3 crore (30 Million Indian Rupee) on 26 February 2016.
The Central Crime Branch of Greater Chennai Police on Thursday busted a fake ball bearing racket operating out of Broadway. They seized Rs 3 crore (30 Million Indian Rupee) worth fake ball bearings which were being sold under the brand name of the Swedish firm SKF.
The CCB team has also arrested eight persons, including two brothers who were masterminded the racket. According to the police, the brothers purchased cheap quality ball bearings from Mumbai and then repackaged them as SKF bearings. They had forged the seals and other imprints to sell their wares as genuine products, the police said.
To save any further weight and to bind ultra-lightweight components, an increasing number of manufacturers are relying on high-performance adhesives. As market leader, Henkel Adhesive Technologies is currently exhibiting its innovative portfolio at the composite trade fair JEC in Paris.
In numerous industries lightweight materials have developed into a crucial success factor for resource efficiency: In the automotive and aerospace industry, for example, weight reduction leads to a lower fuel consumption. Solutions by Henkel help engineers around the globe to design and construct lightweight components, for which the adhesives need to overcome several challenges. In the aerospace industry Henkel solutions ensure 30 percent less weight than materials that are made of steel or aluminum. Therefore, a high adhesive power, faster curing and the possibility to bind them with various other materials is important. Matrix resins serve the production of particularly lightweight fiber-reinforced composite structural components.
The majority of lightweight materials is used in the automotive industry. Manufacturers must react to more severe emission regulations in Asia, Europe and the United States. For electrically powered cars it is necessary for the efficient but heavy batteries to be placed only into extremely lightweight cars, which can then ensure a more attractive reach. Modern industrial adhesives and composite materials reduce the weight of cars by up to 15 percent. They replace, for example, the steel used for the body of the car or for the axle, and heavy bitumen mats for sound absorption in vehicles. A further application is for coatings that improve the corrosion protection and the wear and tear of lightweight metal components.
