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 acetal for higher torque and torsional stiffness capabilities than nylon. 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 ExternallyAssignedProductIdentifier : 7468234469896 ExternallyAssignedProductIdentifier1 : 634529059937 ExternallyAssignedProductIdentifier2 : 0634529059937 IncludedComponents : Product & Instructions Guide ItemName : Ruland OD12/19-AT Oldham Coupling Disk, Black Acetal, Bore, 3/4" or 19.1mm OD ItemPackageDimensions_Height : 0.254 centimeters ItemPackageDimensions_Length : 12.954 centimeters ItemPackageDimensions_Width : 10.16 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : disc-couplings Manufacturer : Ruland Material : acetal ModelNumber : OD12/19-AT NumberOfBoxes : 1 NumberOfItems : 1 PartNumber : OD12/19-AT 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 : 2014-09-06T09:09:44.824Z SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 1
