Specification Brand : Ruland BulletPoint : 664062-2 BulletPoint1 : Ruland oldham couplings have a zero-backlash balanced design for reduced vibration at speeds up to 4,500 RPM. They can accommodate high amounts of parallel misalignment (up to 10% of the hub OD). BulletPoint2 : Acts as a mechanical fuse stopping power transmission during a torque overload. User can combine clamp or set screw hub with inch, metric, keyed, or keyless bore for a high level of customization. BulletPoint3 : Made from nylon for dampening and noise reduction. BulletPoint4 : Proprietary hub machining process for smooth interaction between the hub and disk allowing for significantly longer life. BulletPoint5 : Ruland oldham coupling disks are RoHS3 and REACH compliant ConstructionType : Coated ExternallyAssignedProductIdentifier : 7468234469896 ExternallyAssignedProductIdentifier1 : 634529059944 ExternallyAssignedProductIdentifier2 : 0634529059944 ExternallyAssignedProductIdentifier3 : 00634529059944 IncludedComponents : Unit^Instruction Guide ItemName : Ruland OD12/19-NL Oldham Coupling Disk, Nylon 11, Bore, 3/4" or 19.1mm OD ItemPackageDimensions_Height : 1.27 centimeters ItemPackageDimensions_Length : 8.128 centimeters ItemPackageDimensions_Width : 13.208 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : disc-couplings Manufacturer : Ruland Material : nylon_11 MaximumRotationalSpeed : 4500 rpm ModelNumber : OD12/19-NL NumberOfBoxes : 1 NumberOfItems : 1 PackageLevel : unit PartNumber : OD12/19-NL ProductDescription : 'Motion Control Coupling, Oldham Coupling Disc, Outside Dia 0.750 In, Outside Dia 19.10 mm, Torque Nominal 5 In-Lbs, Torsional Stiffness 0.140 Deg/In-Lbs, 4500 Max RPM, Max Temp 130 F, Nylon Material, Plain Finish, Nylon Disc Type' ProductSiteLaunchDate : 2012-12-14T23:06:07.959Z SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 1
