thrust ball bearing
Descripton
High-carbon chromium bearing steel is widely used in the world, the
most commonly used types are GCr15 and GCr15SiMn, the performance
of the two kinds of steel is basically the same, but the quenching
permeability of GCr15SiMn is better than GCr15, so for larger size
bearing parts, should adopt GCr15SiMn steel, high-carbon chromium
bearing steel is widely used in the manufacture of rolling bearing
rings and rolling parts.
GCr15 bearing steel is widely used to manufacture spindle bearings,
railway bearings,engine bearings, machine tools bearings, mining
machinery bearings, general machinery bearings etc.
GCr15SiMn bearing steel is mainly used to manufacture thick wall
bearings, such as large and extra large size bearings, used in
heavy machinery and rolling mill machinery.
Material Characteristics
Found primarily in ball bearing designs and a variety of demanding
industrial applications. A vacuum-degassed AISI E52100 chrome steel
is used to obtain a superior ball with a fine surface finish,
through-hardness and high load capacity. Also available in
consumable electrode vacuum melt material.
Related Introduction
Grade: The designation assigned, based upon a combination of dimensional accuracy and surface roughness.
Deviation from Spherical Form: Measurement of the lack of roundness
from the ideal spherical form.
Lot Diameter Variation: Measured dimensional difference between the
largest and smallest balls as produced in a group / heat.
Nominal Ball Diameter Tolerance: The measured minimum and maximum
variation in diameter from the ideal dimension.
Maximum Surface Roughness: The maximum measured irregularity determined from the ideal smooth
form.
We mainly produce chromium steel with a size of 7.9375mm to
82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
The ball has high precision, good surface smoothness, standard hardness and excellent wear resistance. Our products have been widely exported to Europe, America, Japan, Korea etc.
The best precision, make your bearing roll smoother.
Solid Chrome Steel Balls
Well-Made
Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each steel ball.
High Hardness
Ball hardness is controlled within the HRC60-67 range as measured on parallel flat surfaces.
Wide Applications
The High Quality Chrome Steel Balls are mainly applied in Deep Groove Ball Bearing, Angular Contact Ball Bearings, Thrust Ball Bearings, Wheel Hub Bearings, Linear Bearings,wind turbine bearing, slewing ring bearing and also the Bearing.
