NSK 6000-2RS Deep Groove Ball Bearing

 Deep groove ball bearings are simple and easy to use, which is the largest production volume, most widely used for a class of bearings. It is not only mainly used for radial load, but also  certain axial load. They are high precision and long life with low noise and vibration. And various types are available.

Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies.

 These products, which are of simple design, robust in operation and easy to maintain, are available in single and double row designs and in open and sealed variants. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields. Due to their low frictional torque, deep groove ball bearings are suitable for high speeds.

Series: 60, 61, 62, 622, 63, 623, 64, 618, 619, 160, 60

Single row deep groove ball bearings

Single row deep groove ball bearings are the most frequently used type of rolling bearing. They are produced in numerous sizes and designs and are particularly economical.

 Sealing

Open bearings are suitable for high to very high speeds.

 Deep groove ball bearings with the suffix 2Z have gap seals on both sides and are suitable for high speeds.

 Bearings with the suffix 2RSR have lip seals on both sides made from nitrile butadiene rubber NBR and are suitable for moderate speeds

Double row deep groove ball bearings

Double row deep groove ball bearings correspond in their structure and function to a pair of single row deep groove ball bearings. They are designed for high to very high speeds and are used where the load carrying capacity of single row deep groove ball bearings is not sufficient.

Double row deep groove ball bearings are wider than single row deep groove ball bearings of the same bore and outside diameter but have a significantly higher load carrying capacity.

Cages

Single row deep groove ball bearings without a cage suffix have a sheet steel cage.

 Deep groove ball bearings with ball-guided solid brass cages are indicated by the suffix M.

 The suffix Y indicates bearings with a sheet brass cage.

 Double row deep groove ball bearings have cages made from glass fibre reinforced polyamide (suffix TVH).
