Deep groove ball bearings

1)Materials for rings and rolling elements


While the contact surfaces between thebearing rings and rolling elements are subjected torepeated heavy stress,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 dimension alstability
●Highmechanical strength

The material used by our company is high carbon chromium bearings steel GCr15-GB/T18254 equivalent such as AISI 52100(USA),DIN100Cr6(Germany) JISSUJ2(Japan) and BS534A99(UK).

2)Materials for cages

The materials for cages must have strength towith stand rotation at load and shock load. Low frictional efficiency light weight and be able to with stand operation temperature.

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

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

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

3)Vibration and noise

●The measuring parameter of vibration adopted by RNB is the vibration acceleration ofvibration 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 besupplied with as maller C2 clearance or the much greater C4 or C5 clearances. Inaddition, deep groove ball bearings are available with reduced or displacedinternal clearance ranges. These special clearances may use reduced ranges ofstandard clearance classes orpartitions of adjacent classes, see designationsuffix CN in section.

5)Tolerances

Single row deep groove ball bearings are manufactured as standard tonormaltolerances.

Single row deep groove ball bearingsare 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/–60μmfor bearings with outside diameter up to 110 mm
-0/–100 μm forlarger bearings.

The running accuracy depend on the bearing size andcorrespondsto

-   P5 tolerances for bearings up to a 52mm outside diameter
-   P6 tolerances forbearings above 52 mm up to 110 mm outside diameter
-   Normal tolerances forlarger bearings.

For bearing arrangements where accuracy is a key operational factor, some 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.
