Deep groove ball bearing is the most typical rolling bearings with extensive applications. The raceways in both of the rings are in the arc groove form, which can carry radial load and axial load in double directions. They can be applied in situations where high rotating speed and low noise and low vibration are required.

Adequate lubricating grease shall be filled before hand in the sealed bearings and shielded bearings.

For bearings with filling slot, the number of the steel balls can be increased, leading to higher basic load ratings.

Applications of deep groove ball bearings can be found in automobiles, machine tools, motors, instruments, construction machines, railway vehicles, agricultures machines and various other special machines.

Horton deep groove ball bearings have the following types:

- Basic type.(fig1) Applications of this type can be found in situations where there are no special requirements for mounting and sealing.

- Bearings with snap ring groove,(fig2) with or without snap ring.

- With one shield (-Z) on one side or two shields (-2Z) on both sides. The shields are made of steel sheet. Adequate lubricating grease has been put in the deep groove ball bearings with two shields during manufacturing process and there is no need to heat or clean the bearing or add lubricating again. It is non-contact seal, and compared with deep groove ball bearings with seals, they have less friction and suitable for applications with high rotational speed requirement.

- Sealed bearings.(fig3) The seals are made of rubber with steel sheet reinforcement. It is contact sealing. Compared with the shielded deep groove ball bearings, they are better in terms of dust-resistance, water-resistance. However, the friction shall be larger and the rotating speed is to certain extent limited.

- Double row deep groove ball bearings.(fig4)

Double row deep groove ball bearings correspond in design to single row deep groove ball bearings. They have deep uninterrupted raceways and high conformity between the balls and raceways. They are able to carry axial loads acting in both directions in addition to radial loads.

- Stainless steel deep groove ball bearings.

Stainless steel deep groove ball bearings are resistant to corrosion from moisture and several other media. These single row deep groove ball bearings have the same deep raceway grooves and close conformity between raceways and balls as standard deep groove ball bearings made of carbon chromium (rolling bearing) steel. They are without filling slots and can carry axial loads acting in both directions in addition to radial loads, even at high speeds.

Cages

Deep groove ball bearings generally used pressed steel cages or brass cages. When the outer diameter is less than (inclusive) 400 mm, they use pressed cage with steel sheet and there is no suffix in the bearings code number. When the outer diameter is greater than 400mm, they use brass cages and there is no suffix in the bearings code number. 

Permissible Angular Misalignment

Deep groove ball bearings permit angular misalignment between the inner ring and outer ring. The details are given in terms of radial clearance in the following table:
