• WHAT IS A HYBEID CERAMIC BEARING? A ceramic hybrid bearing is a combination of ceramic balls and bearing quality metal rings.Which combine hardened steel rings with rolling features made from high-performance ceramic materials, are an more and more common option for aggravating applications. TECHNICAL SPECS Model: 6803 RSStructure: Deep Groove BallMaterial: Hybrid CeramicBore Dia (d): 17 mmOuter Dia (D): 26 mmWidth (B): five mmClover: Sealed (2RS)Lubrication: GreaseClearance: C0Quantity: 1 Lot = 1 PC Special Note: ---1, Sometimes the cages will be different.eg.: 67 sequence thin-walled bearings, since the inner wall is awfully thin, will use the crown-shaped iron cage.---2, The grease and sealed are settle for custom-made, so occasionally there are various colors of the rubber sealed.If you mind the sealed color, please touch us. We'll confirm the stock for you.---3, The normal clearance of bearings is ISO ordinary C0, the United States common K25, the clearance cost is 3-18um;If you've got particular standards for swinging, please touch us before procuring to confirm. This Bearing Structure Standard Type: A ball bearing consists of an outer and inside ring, balls, seal and a retainer.52100 Chrome Steel Outer Ring & Inner Ring +Si3N4 Ceramic Balls +Nylon Cage + Grease + Sealed= Hybrid Ceramic Bearing This Bearing Cover Compared to the open type, the shielded and sealed bearing forms present greater protection from contamination and grease leakage. They are selected in line with the appliance type and environment.This is 2RS double sealed. This Bearing Lubrication One of the largest points requiredfor the nice operate of bearing preparations is right lubrication.The lubricant separates the steel bearingsurfaces and thereby reduces friction, preserves the metal parts and acts as an additional barrier opposed to the access of contaminations or impurities into the bearings. This Bearing Cage Retainers maintain the balls separated and equally spaced. Retainer forms are set according to the bearing size yet would be chosen in keeping with the required performance.This is manufactured from Nylon PA66 Cage. This Bearing Material The most common material used to produce the burden carrying elements in curler bearings is 52100 stainless steel (bearing steel). These components are the bearings inner and outer rings, balls and rollers. The chemical composition of this steel has excessive carbon and about 1.5% chromium content. Using managed processing and heat-treating methods the completed bearing ingredients have high strength to face up to cracking and a hard floor to resist subsurface rolling contact fatigue. The usual surface hardness for bearing elements manufactured from this material ranges from 60- 64 at the Rockwell hardness C scale (Rc). This Bearing Balls Due to this veritably very small contacting area ballbearings have less frictional resistance and aremore compatible in excessive pace applications.This is made from Si3N4 Ceramic. This Bearing Clearance The term “clearance” is temporarily described because the distance that bearing substances may perhaps stream relative to each other at physical extremes.CN (C0) “normal” clearanceThis clearance group is explained because the standard. Thus CN isn't always marked on the bearings. Historically the conventional clearance changed into designated as “C0“.C2 clearance range smaller than CNC3 clearance vary larger than CN This Bearing Grade Executive standard:GB/T 307.1-2005 Rolling bearings Radial bearings Tolerance MORE BEARINGS DETAIL Applications: Bicycle Hub FEEDBACK & OUR SERVICE
