Deep groove ball bearings 6803ZZV

1) Materials for rings and rolling elements

While the contact surfaces between the bearing rings and rolling elements are subjected torepeated 

heavystress,they must still maintain high rotational precission,therefore, the materials used for bearings 

rings and rolling elements require the following characteristics:

●High rolling contact fatigue strength

●High hardness

●High wear resistance

●High dimensional stability

●High mechanical strength

The material used by our companyis high carbonchromium bearings steel GCr15-GB/T18254 equivalent such as 

AISI52100(USA),DIN100Cr6(Germany) JISSUJ2(Japan) andBS534A99(UK).

2)Materialsfor cages

The materialsfor cages must have strength towith standrotation at load and shock load. Low frictional 

efficiency light weight andbe able to with stand operation temperature.

The material used in ribboncagesor crown cages is 08F orSPCC pressed.

It is chemical compositionis shown for extra-high speed application. Plastic cages such as glass reinforced polymideareused.


These plastic crown have the advantages oflow torque,long grease lefe and low noise,etc.

3)Vibration andnoise

●The measuring parameter of vibration adopted by RNB is the vibration acceleration of vibration velocity.

● The measuring units and measuring method arespecified by JB/T5314 and JB/T5313 In the process of measuring vibrationstrictly controlled noise by using acoustics.

4)Internal clearance

Single row deep groove ball bearings are manufactured with Normal radial internal clearanceas standard. 

Most of the bearings are also available with C3 radial internal clearance. Some of the bearings can also be

supplied with as maller C2 clearance or the much greater C4 or C5 clearances. In addition, deep groove ball

bearings are available with reduced or displaced internal clearance ranges. These special clearances may 

use reduced ranges of standard clearance classes orpartitions of adjacent classes, see designation suffix

CN insection.

5)Tolerances

Single row deepgroove ball bearings are manufactured as standard to normal tolerances.

Single row deep groove ballbearingsare produced to higher precision than the ISO Normal tolerances. The 

dimensional accuracy corresponds to P6 tolerances, expect the width tolerance,which is considerably tighter

andreduced to 


-0/–60μm for bearings with outside diameter up to 110 mm
-0/–100 μm for larger bearings.

The running accuracy depend on the bearing size and correspondsto 

-   P5 tolerances for bearings up to a 52mm outside diameter

-   P6 tolerances for bearings above 52 mm up to 110 mm outside diameter

-   Normal tolerances forlarger bearings.

For bearing arrangements where accuracy is a key operational factor, some SKF single row deep groove ball 

bearings are also available with accuracy completely to P6 or P5 tolerance classs pecifications.The 

availability of these bearings should always be checked before ordering.
