Deep Groove Ball Bearing Manufacturer

Deep Groove Ball Bearings Single Row

Single-row ball bearings have only one raceway and last a long time. They can withstand high temperatures due to ceramic coating, enduring temperatures up to 660°F. The last single-row bearings have a sensor bearing unit that helps measure the angular position and speed. Bearings with sensors are common in electric motors, conveyors, road rollers, tractors, etc.

You can get single-row deep groove ball bearings with bore sizes from 3 mm to 400 mm in miniature, thin, or wide bearing types.

Deep Groove Ball Bearings Double Row

Compared to single-row deep groove ball bearings, double-row ball bearings have two rows of bearing balls. Thus, they are also slightly wider than their single-row counterparts. The design supports significantly higher loads while maintaining low noise and friction. So, they can be made in different sizes according to the load requirements.

However, these ball bearings do not have shields or seals; some may have cages that help with assembly and installation but are not very robust. It makes it incredibly important to choose the right type of cage material for a specific purpose.

Deep Groove Ball Bearing Contact Angle

Contact angle ball bearings have a 15°, 25°, or 40° angle between the ring and the ball. A higher contact angle shows greater axial capacity, whereas a smaller contact angle is more suitable for high-speed rotation applications. These single-row ball bearings can withstand unidirectional axial, radial, DB, and DF combination loads. At the same time, double-row contact angle bearings can support unidirectional axial load.

So, angular contact ball bearings are preferred for high-precision, high-speed rotating purposes.

Sealed Deep Groove Ball Bearings

Sealed deep groove ball bearings are a type of single-groove ball bearings with rubber or steel shields on one or both sides. Sealed bearings are pre-lubricated to increase the life of the ball bearing. They are commonly used in contamination-prone environments to ensure the contamination does not impact the bearing’s performance. Also, the grease allows smooth movement for a longer time.

Maximum Type Ball Bearings

If you are looking for an all-rounder deep groove ball bearing China to meet your deep groove ball bearing needs, you might have found the best one here. Maximum-type ball bearings have more balls than single and double rows, allowing high precision with added longevity. The best part is that they perform better without additional wear and tear. Maximum-type ball bearings can be opened or sealed type, depending on your requirements.
