Deep groove ball bearings 5 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 surfaces. New products are subjected to...

Deep groove ball bearings 7 ZZ Non-contact shield VV Non-contact seal DDW Light-contact seal DDU Contact seal 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. Different cages for different applications Within our deep groove ball...

Deep groove ball bearings 11 Automotive industry Whether in a gearbox or alternator, deep groove ball bearings are an important part of any automobile. Thanks to our specially developed materials, heat treatment, sealing and lubricants, NSK deep groove ball bearings offer high performance and reliability. This way, for example, our patented TM seals make it possible for oil to move through gearbox bearings while foreign bodies are kept at bay. And for alternators that suffer early bearing failure due to the effects of vibration and micro slippage, we developed our HAB lubricant, a product...
