stainless steel ball bearing different sizes of steel ball bearings

These are stainless steel ball bearings , you can see different sizes of steel balls inside.There are many companies that manufacturer of semi-precision Stainless Steel Balls. Most of its purpose are on valve pumps,appliance components ,sprinkling systems, casters, drawer slides, locking mechanisms, semi-precision bearings.Stainless Steel balls are passivated.Stainless Steel ball materials such as 302, 304, 316, 316L, 316L VM, 420, 430, 440, and Nitronic 50.

Chrome stainless steel balls 302 As small as 0.3mm is Slighty Magnetic Austenitic Good corrosion resistance Retains tensile strength at high temperatures and are used for Dispenser valve balls.

The industry demands for high anti-corrosion stainless steel ball bearings and the ability to withstand fierce conditions while maintaining the preciseness of ball bearings.

Materials used for stainless steel ball bearings are AISI 440C martensitic stainless steel is used for inner rings, outer rings and balls. AISI 304 austenitic stainless steel is used for retainers and metal shields. Standard material of rubber seals is nitrile butadiene rubber and fluorinated rubber, acrylic rubber.440C stainless steel is magnetized steel.

Precision of stainless steel ball bearings are dimension tolerance and rotational precision grade over ISO Normal Class or ABMA(used to be AFBMA)ABEC-1 is guaranteed. ISO CLASS 6 or ABEC-3 and ISO CLASS 5 or ABEC-5 .

Lubrication stainless steel ball bearings for are special high temperature greases such as silicon grease, fluorinated grease.

stainless steel ball bearings has high resistance to corrosion and high stability in high temperature (Higher available operating temperature by approximately 50 degrees C, or, 122 degrees F than normal bearing steel)and High resistance to chemicals.

The demand for higher performance and durability of ball bearings has increased. You may also read about tapered roller bearings.
