6900 Series - Metric dimensional series for limited space applications and heavier loadsTECH DEATAILSItem: 6902 2RSStructure: Thin Section Ball BearingMaterial: 52100 Chrome SteelType: Rubber Sealed ( RS )Bore Dia (d): 15 mmOuter Dia (D): 28 mmWidth (B): 7 mmClearance: C0Grades: ABEC-1Lubrication: With GreaseQuantity: 1 Lot = 10 PCSThis Bearing StructureStandard Type: A ball bearing is composed of an outer and inner ring, balls, seal and a retainer.This Bearing CoverCompared to the open type, the shielded and sealed bearing types provide better protection from contamination and grease leakage. They are selected based on the application type and environment.This is 2RS double rubber sealed.This Bearing LubricationOne of the most important elements required for the effective function of bearing arrangements is correct lubrication.The lubricant separates the metallic bearing surfaces and thereby reduces friction, preserves the steel parts and acts as an additional barrier against the entry of contaminations or impurities into the bearings.This Bearing CageRetainers keep the balls separated and equally spaced. Retainer types are set based on the bearing size but can be selected based on the required performance.This is made of steel ribbon.This Bearing MaterialThe most common material used to produce the load carrying components in roller bearings is 52100 chrome steel (bearing steel). The typical surface hardness for bearing components made from this material ranges from 60- 64 on the Rockwell hardness C scale (Rc).This Bearing BallsDue to this usually very small contacting area ball bearings have less frictional resistance and are more suitable in high speed applications.This is made of steel.This Bearing ClearanceThe term "clearance" is briefly described as the distance that bearing components m
