WHY 440C STAINLESS steel?Good corrosion resistance to water and many weak chemicalsCorrosion resistance can be improved by passivationGood for temperatures up to 300°CSlightly softer than chrome steel so lower load ratingsWill corrode in salt water or salt spray and poor resistance to acids/alkalisMore expensive than chrome steelTECHNICAL SPECSItem: S6906RSStructure: Deep GrooveMaterial: 440C Stainless Steel ( prefix "S" )Bore Dia (d): 30 mmOuter Dia (D): 47 mmWidth (B): 9 mmClosures: Glue cover Shielded(RS)Lubrication: GreaseMagnetic: littleHardness: 58HRCCorrosion Resistance: GeneralClearance: C0Grades: ABEC Grades 3Weight: 46 gQuantity: 1 Lot = 5 PCSDIMENSIONSSPECIAL NOTEDear friend, Please read this email before your purchase.Seal cover color this can not be guaranteed,sent randomly.If the seal color is important to you, please give us a message to confirm.Hope is also helpful to you.Best Regards,High-concerned chemical : NoneModel Number : S6906RSMaterial : Stainless SteelSize : 30*47*9 mmUse : Road Bicycles

• High speed, low friction coefficient, low vibration and noise.
• Ball bearings are single row bearings that support radial loads, made of chromium steel, and have excellent quality and durability.
• Widely used: These bearings are widely used in various small machinery, including electric toys, furniture wheels, skateboard wheels, inline skating shoes, etc
• Material: Chromium steel, characterized by fast running speed, low noise, high temperature resistance, and smooth rotation
• Pre lubrication: The bearings are coated with a small amount of lubricating oil, which will extend the service life of the product
