DEEP GROOVE BALL BEARINGS

NSK – the World’s leading deep groove ball bearing manufacturer Deep groove ball bearings, the most common form of rolling bearings, are used in many types of applications; particularly those where high speeds and low power loss are required. NSK deep groove ball bearings can handle not only radial forces, but also moderate axial loads in both directions. They are easy to install and can be deployed in a variety of configurations. Research and development At NSK, we invest around 100 million Euros a year in research and development of new bearing technologies, lubricants, materials and...

NSK quality is to be found in every detail Because we focus rigorously on quality in raw material choice and in the finishing processes, NSK deep groove ball bearings guarantee strong performance, quiet running and maintenance-free operation for many years. In much the same way that every product is carefully checked several times using automated measuring equipment, each assembled unit undergoes various tests before delivery in order to guarantee the highest quality. Z-Steel › ultra pure steel that increases a bearing´s life by up to 80 % Advanced lubrication technology › for more...

World leader in seal technology NSK shields and seals offer years of trouble-free operation. The patented labyrinth construction ensures the highest levels of sealing and, due to low torque, ensures low power loss too. The standard sealing material is an environmentally friendly nitrile rubber compound. Other materials are also available, for use in high temperature or corrosive environments, for instance. Shield and seal comparisons ZZ Dustproofing Waterproofing Torque Constant revolutions Protection against lubrication leakage Different cages for different applications Within our deep...
