Deep Groove Ball Bearings
NSK is the World Leader in deep groove ball bearings.
We have achieved our position over a number of years by pushing Deep Groove Ball Bearings beyond that of any other manufacturer. By extending the normal boundaries of performance and functionality we are able to offer deep groove ball bearings that extend machine life and provide years of maintenance free service.
NSK manufactures a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications. Not only are they capable of supporting radial loads but also moderate axial loads in either direction. Due to their low torque, they are suitable for applications where high speed and low power loss is required. They are easy to mount and suitable for many different configurations.
Features and Benefits of Deep Groove Ball Bearings:
• High Quality Steel - Ultra clean steel to extend bearing life by up to 80%.
• Advanced Grease Technology - NSK lubricants that can extend grease life and performance of deep groove ball bearings .
• High Grade Balls - Quiet and smooth operation even at high speed.
• Super Finished Raceways - Specially honed to minimise noise and improve lubricant distribution and life.
• Patented Seals - Provide resistance to contamination in the toughest environments.
• Cages - Offering a number of different cage types to suit your application needs.
• Quality Assured - 100% testing ensure total product quality.
Single Row Deep Groove Ball Bearings
Single row deep groove ball bearings are the most common type of rolling bearing and are used in a wide variety of applications.
Magneto Bearings
The inner groove of magneto bearings is a little shallower than that of deep groove bearings. Since the outer ring has a shoulder on only one side, the outer ring may be removed. This is often advantageous for mounting.
Miniature Ball Bearings
NSK offers a full range of metric and inch size miniature ball bearings with bore diameters of less than 10mm.
Ball Bearings for Automotive
Ball bearings are used in automotive applications such as motors, compressors, and alternators.
TF Series Bearings
Designed for outstanding toughness under harsh conditions, combining longer service life & superior resistance against wear, seizure & heat.
Creep-Free Bearings
Tensioned O-rings mounted in the bearing outer ring improve creep prevention under rotating loads. The product offers easy assemble and the possibility of reusable housings.
Sensor bearings
Sealed for life, maintenance free, these high performance ball bearings have superior resistance to magnetic flux.
Fretting-Resistant Servomotor Bearings
Fretting resistant & long-life servomotor bearings are utilised where precise motion control is vitally important.
Prelubricated bearings with EA3 grease
Long life, low torque ball bearings - EA3 grease is pre-filled in shielded/sealed ball bearings used in a wide range of electric motors to maximise life and protection, but minimise noise and power loss.
Bearings prepacked with LG2/LGU grease
LGU and LG2 greases achieve lower particle emissions and longer service life in comparison to conventional fluorine greases.
