Specification Brand : JIUWU BulletPoint : COMPATIBLE WITH THE FOLLOWING DEVICES: TRUWAVE PLUS, NEXWAVE, EWAVE, IF-8100, AND IF-8000 BulletPoint1 : Precise Size: The 3x8x4 mm miniature size is designed for high precision and ensures stable operation in tight spaces. This miniature size is suitable for a wide range of precision machinery and equipment, providing reliable support BulletPoint2 : High-Quality Materials: Miniature steel bearing is made of high-quality steel with excellent wear and corrosion resistance, which ensures stable operation for a long period of time. Steel ball bearing can maintain stability whether it is rotating at high speeds or working under high loads BulletPoint3 : Low Friction Design: The precision lubrication system inside the roller bearings reduces friction and wear and improves mechanical efficiency. This low friction design not only extends the life cycle of small ball bearings, but also reduces energy consumption BulletPoint4 : Silent and Efficient: The optimised design makes the steel ball bearing run more smoothly and with low noise.8mm bearing can keep stable and silent even under long time high speed operation, which ensures the high efficiency and comfort of the equipment operation BulletPoint5 : Widely Used: Small bearings are suitable for a variety of fields, such as model making, mechanical equipment, electronic products, etc. Ball bearing rollers can play a stable and reliable role as wheel bearings of model vehicles or key components of mechanical equipment CustomerPackageType : Standard Packaging ExternallyAssignedProductIdentifier1 : 701385464790 ExternallyAssignedProductIdentifier2 : 0701385464790 ItemName : 3x8x4 mm Miniature Steel Bearing Skateboard Deep Groove Ball Bearings Pack of 10 ItemPackageDimensions_Height : 5.0038 centimeters ItemPackageDimensions_Length : 0.7112 centimeters ItemPackageDimensions_Width : 3.0988 centimeters ItemPackageQuantity : 10 ItemTypeKeyword : deep-groove-ball-bearings Manufacturer : JiuWu Material : Alloy Steel ModelNumber : 693ZZ, R-830ZZ, 619/3 NumberOfItems : 10 PartNumber : ZC004 ProductDescription : 100% New Never Used Features: Item:693ZZ Ball Bearings Widespread bearing,economic and standard Easy Installation & Replacement Less Friction, Higher Speeds Durable & Insulation Specification: Model:693ZZ,R-830ZZ,619/3 Material: Bearing Steel Inner diameter: 3mm Outer diameter: 8mm Thickness: 4mm Package included:10pcs Ball Bearings ProductSiteLaunchDate : 2015-06-12T07:09:58.831Z Size : 3*8*4mm SpecificationMet : ABEC 3 SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 1
