Made In China Stable High Quality Single Row Open/ZZ/2RS Steel&Brass Cage 61834 61844 Deep Groove Ball Bearing

Single row deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility and overall performance. They are characterized by having deep raceway grooves in which the inner and outer rings have circular arcs of slightly larger radius than that of the balls. They also have non-separable rings. 

As flexible as the performance is, the configurations of single row ball bearnigs is also as versatile. These bearings often have steel shields or rubber seals installed on one or both sides and are pre-lubricated with grease. Also, snap rings are sometimes used on the outside edge. While many different retainers are available, pressed steel cages are most commonly used. Even tapered bores are available upon special order.

Bearing Ring - Contains inner and outer rings.Made of high quality steel, it can prolong the service life of bearing efficiently

Rolling Element - Transfer the load between the inner and outer rings

Retainer - Reduce friction heat, optimize load, and easy to disassemble

Integral Seal - Greatly extend the service life of the bearing, keep lubricant in the bearing and keep contaminants out

Bearing Parameters

According to the size of deep groove ball bearing can be divided into:

·Miniature bearing -- outer diameter of less than 26mm;

·Small bearings -- outer diameter ranging from 28-55mm;

·Small and Medium-sized bearings --  outer diameter ranging from 60-115mm;

·Medium and Large bearings --outer diameter range of 120-190mm

·Large bearing -- outer diameter range of 200-430mm;

·Extra-large bearing --outer diameter of more than 440mm.

The parameters of Miniature bearings are as follows:
