What are the Characteristics of Double Row Deep Groove Ball Bearings?

● The characteristics of double row deep groove ball bearings with ball loading notch

Double row deep groove ball bearings with ball notch have a ball notch on the inner ring and outer ring, which can be filled with more and larger balls than general purpose deep groove ball bearings. Bearings with ball notch have higher radial load carrying capacity than those without ball notch, but their axial load carrying capacity is smaller. This type of bearing has low speed performance. Depending on the application, deep groove ball bearings with ball loading notch are available with or without cage.Small size of this type of bearing is mainly used in automotive gearboxes with cage. Large bearings for heavy load, low speed rotating applications without cages.

● The characteristics of the magnetic motor ball shaft

Magnetic motor bearings are deep groove ball bearings (in the past we often mistakenly think of angular contact ball bearings), inner ring groove than deep groove ball bearings slightly shallower, no retaining edge side of the outer ring inner diameter from the groove bottom of the outer ring is a cylindrical surface, the outer ring can be separated, easy to install bearings.Normally, 2 bearings are used in opposition to each other. This bearing is a small bearing with an inner diameter of 4mm~20mm generally using copper alloy stamping cage. It is mainly used for small generators, rotary instruments, measuring instruments, etc.

●The characteristics of stainless steel deep groove ball bearings

Stainless steel deep groove ball bearings are resistant to moisture and corrosion, and like chrome steel deep groove ball bearings, they have deep bearing raceway grooves, and the fit between the bearing raceway and the ball is extremely high. These bearings do not have filled grooves, and in addition to radial loads, they can also withstand axial loads acting in both directions, even at high speeds.

The operating characteristics of stainless steel deep groove ball bearings are the same as conventional steel deep groove ball bearings, but the load carrying capacity is lower. There are open type and closed type designs, and the bearing size is generally 1mm~50mm.
