Deep groove ball bearings

Deep groove ball bearings are simple structure bearings that are easy to use and achieve high manufacturing precision production. These deep groove ball bearings are highly versatile, have very low friction, and are optimized to reduce noise and vibration for higher rotational speeds.

Suitable for high rotation speed operation, they are extremely durable and require little maintenance.

When the clearance between the bearing and its housing increases, it functions like an angular contact ball bearing. As a result, it can withstand alternating axial loads in two directions.

Deep groove ball bearings are the widely used rolling bearings, mainly used to bear radial loads, and can also bear certain axial loads. Its main application areas include automobiles, tractors, machine tools, motors, water pumps, agricultural machinery, textile machinery, etc.

Structural classification of 64 series deep groove ball bearings

According to the classification of seals, 64 series deep groove ball bearings can be divided into those without and those with seals.

Below is the structure without seal:

64 series bearings are deep groove ball bearings with seals or shields (bearing suffix 2RS1); this type of embedded seal can greatly extend the service life of the bearing because it prevents grease leakage and contamination from entering. 

The structure diagram is as follows:

According to the classification of cage materials, 64 series bearings can be divided into steel cages and copper cages.

Steel cage: high strength, lightweight compared with copper cage.

Copper retainer: good wear resistance, anti-friction effect, low noise, and higher limit speed.
