What does NSK mean on a bearing?

The designation for the NSK bearing bore indicates the bearing’s bore size. A two-digit number is used for bore sizes from 20mm to 480mm. This number is multiplied by five to give the bore size. For example, the code 6318 stands for a deep groove ball bearing with a bore size of 90 mm.

Why deep groove ball bearing is used?

These deep grooves result in balls that are more stable and can handle higher loads than shallow-groove bearings. They still provide low friction, and the deep groove also limits vibration and noise while also providing the ability for some axial load capacity.

What is a 6203 ball bearing?

The 6203 is a 17 mm Ball Bearing that can be used in many rotary and factory automation applications. The 6203 Deep Groove Ball Bearings is an open style bearing. The 6203Z ball bearing is a single row raceway and single shielded. The 6203ZZ ball bearing has a single row raceway and it is shielded on each side.

How are deep groove ball bearings work?

Grooves within the inner and outer rings form the raceway. Rolling elements roll within the raceway. The cage spaces the rolling elements apart from each other. Forms the inner part of an anti-friction bearing (the part that presses against the shaft).

What are deep groove ball bearings made from?

When it is inclined 2’~10′ with respect to the hole of the casing, it can still work normally, but it has certain influence on the bearing life. Deep groove ball bearing cages are mostly steel plated wave cages, and large bearings are mostly made of metal body cages.

Where is deep groove ball bearing used?

Deep groove ball bearings are the most common type of ball bearing. They are commonly used in electric motors and in household appliances, car motors, office machinery, automation control, and garden and household tools.

Are deep groove ball bearings self aligning?

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed.

Can deep groove ball bearings take axial load?

Due to the deep raceway grooves in the bearing rings and the narrow osculation between the raceway grooves and balls, single row deep groove ball bearings can support axial loads in both directions ➤ Figure.
