Deep Groove Ball Bearings
NSK is the World Leader in Deep Groove Ball Bearings.
These Bearings are the most common form of rolling bearings and 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.
Product Features:
- Cages - Offering a number of different cage types to suit your application needs: steel, solid brass or polymer
- 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
- Super Finished Raceways - Specially honed to minimise noise and improve lubricant distribution and life
- Patented Seals - Provide resistance to contamination in the toughest environments.
- Electrically insulated ball bearings available
- Outer diameters up to 2500 mm
Product Benefits:

Ceramic Ball bearings for Fan Motors
Ceramic, anti-electrical corrosion ball bearings which prevent damage to bearings used in fan motors.
Deep-groove ball bearings with special heat treatment
Specially treated bearing steel ensures the components last up to twice as long with contaminated lubricant as conventional deep-groove ball bearings
High Temperature Sealed Deep Groove Ball Bearings
Specially created to run in a contaminated environment, and under high temperatures, up to 150°C.
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.
High capacity - HR Series
Larger rolling elements increase the dynamic load rating - helping improve machinery life performance.
LNG Pump bearings
LNG Pump bearings designed to cope with the applications tough operating conditions & extreme temperatures.
High Capacity Shielded - Deep Groove Ball Bearings
The extra large balls provide higher dynamic capacity & the shields help prevent contamination & retain grease.
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.
