Deep groove ball bearing



Deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread. The raceway grooves on both the inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to radial loads, axial loads can be imposed in either direction. Because of their low torque, they are highly suitable for applications where high speeds and low power loss are required.



 


Structures


1. Basic type 60000


Applications of this type of bearing can be found in situations where
there are no special requirements for mounting and sealing.


2. 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 assembling
process and there is no need to clean the bearing or add lubricant as mounting.
It is noncontact seal, and compared with deep groove ball bearings with seals,
they have less friction and suitable for applications with high rotational speed
requirement.


3. With one seal(-RS)on one side or two seals(-2RS)on both sides


The seals are made of rubber with steel sheet reinforcement. It is contact
sealing that could seal much better but have high friction and low limit
rotation speed if the seals contact with the outside of the inner ring; while it
is non-contact sealing that has the same limit rotation speed as the basic type.
The lubricant has been prefilled in the bearing with seals both sides, so there
is no need to clean and fill the lubricant as mounting.


With snap ring groove on the outer ring (-N)


   The snap ring can be used to locate the bearing in the axial direction
so that the mounting in the housing is simplified.


Cage material


   Deep groove ball bearings generally use pressed steel cages or solid
cages. Phenol resin cage is suitable for application with high limit rotational
speed.


Permissible Tilt Angle


Deep groove ball bearings permit tilting angle between the inner ring and
outer ring. The details are listed in the Table 1.


Tolerance and Clearance  


The tolerance of deep groove ball bearings is P0 basically. P5, P6, P4 and
P2 are available for different application.


The radial internal clearance of deep groove ball bearing is as Table
3.


Dynamic equivalent radial load


Fr-Radial load (kN)


Fa-Axial load (kN)


X-Radial factor


Y-Axial factor


X and Y values see Table below.


Static equivalent radial load


     P0r=Fr[kN]                  


     P0r=0.6Fr+0.5Fa[kN]
