3/16" (4.7625mm+/-0.05) Suj2 Steel Ball for Roller Bearing

AISI 52100 CHROME STEEL BALLS Chrome steel ball ,or high carbon chrome steel ball is actually an alloy steel ball which owes its enhanced properties to the presence of lager proportions of special alloying elements such as chrominum , manganese and silicon than are ordinarily present in carbon steel . It is a universal material for many applications, such as, ball and roller bearing industry and for a variety of automobile applications. Due to through hardening, it has an excellent surface quality , superior wear resistance ,hard hardness and high load bearing capacity. APPLICATION Our Chrome steel balls are applied in bearings such as slew bearing, deep groove ball bearing, thrust ball bearing, self aligning ball bearing, double-row bearing and etc. MATERIAL COMPARISON LIST State China Japan America Germany France Standard GB JIS AISI DIN NF Title GCr15 SUJ-2 52100 100Cr6 100C6 Title GCr15SiMn SUJ-3 100CrMn6 MATERIAL ANALYSIS    AISI 52100 Chrome Steel Balls are manufactured to the following chemical analysis: Steel NO.

One type inside has two cartons. For each carton,  length: 22cm  width:17cm   height:10cm   Another type inside has four cartons: For each carton, length: 15cm  width:12cm   height:10cm    About the outside carton: For each carton,   length: 370mm  width:250mm   height:110mm    Then, we pack our balls using wooden pallet in our export business : 1). Put the plastic paper in the pallet(waterproof). The size of wooden pallet: 860mmm  800mm  750mm 2). Put the ball carton into the pallet ,and fix the pallet. 3) .Hooping the pallet tightly using the steel rods Generally, if you don't want packing with our company's logo and name, we offer neutral packing.
