TECHNICAL SPECSModel: SMR95C 2OS Inner (d): 5 mmOuter (D):9 mmWidth (B): 3 mmGrade: ABEC-7Material: Stainless Steel Rings Closures: Non-Contact Rubber SealedBalls: Si3N4 Ceramic BallsLubrication: Self Lubricated ( NO Grease)Qty: You will get 2 pieces ball bearingsShould I oil ceramic bearings?Full ceramic bearings can be run completely dry.They do not need lubrication to run.Ceramic is non-porous, unlike steel, as a result it is virtually frictionless. Because there is no heat buildup and virtually no friction, full ceramic bearings can be run completely dry.What are the advantages of ceramic balls?1.Since ceramics are hardly corrosive, ceramic rolling bearings are suitable for operation under harsh conditions filled with corrosive media.2.Since the density of the ceramic rolling ball is lower than that of the steel, the weight is much lighter, so the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly extended.3.Since the modulus of elasticity of ceramic is higher than that of steel, it is not easily deformed when subjected to force, so it is advantageous to increase the working speed and achieve higher precision.

• Includes 2 replacement 5x9x3 mm SMR95-2RS Stainless Steel Hybrid Ceramic Ball Bearings.
• Lubricated with Grease,440C Stainless Steel Bearing Material,Ceramic Si3N4 Ball Material.
• Ceramic by its nature is lighter than steel by about 2/3 the wieght, it is harder than steel when it is in ball form and it is virtually frictionless because it is non-porous. A ceramic hybrid bearing has steel races with ceramic balls. The balls will never corrode or rust.
• The Grade 5 ceramic Si3N4 balls will allow the bearing to be lighter and spin 50% faster than a traditional steel bearing.
• This Bearing Can be Used in RC Car, Fishing Reel.
