Specification Brand : Ruland BulletPoint1 : Precision honed bores for superior fit and torque transmission. Does not mar the shaft. Keyways are used for additional torque transmission capabilities and to prevent slippage on the shaft. BulletPoint2 : Proprietary Nypatch anti-vibration hardware prevents galling, maintains high holding power, and allows for multiple screw insertions. Nypatch significantly reduces installation time as no additional screw treatment is needed prior to use. BulletPoint3 : Made from 1215 lead-free steel with proprietary black oxide finish for increased holding power and corrosion resistance. BulletPoint4 : Hardware tests beyond ANSI standards for maximum torque capabilities BulletPoint5 : Ruland rigid couplings are carefully made from select North American bar stock in our Marlborough, Massachusetts factory and are RoHS3 and REACH compliant Color : One Color ExternallyAssignedProductIdentifier : 8677826709817 ExternallyAssignedProductIdentifier1 : 634529001721 ExternallyAssignedProductIdentifier2 : 0634529001721 ExternallyAssignedProductIdentifier3 : 00634529001721 IncludedComponents : Electric Couplings ItemName : Ruland CLC-16-16-F One-Piece Clamping Rigid Coupling with Keyway, Black Oxide Steel, 1" Bore A Diameter, 1" Bore B Diameter, 1-3/4" OD, 3" Length, 1/4" x 1/4" Keyway Width ItemPackageDimensions_Height : 4.572 centimeters ItemPackageDimensions_Length : 7.62 centimeters ItemPackageDimensions_Width : 4.572 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : beam-couplings Manufacturer : Ruland Manufacturing Material : Black Oxide Steel MaximumRotationalSpeed : 6000 rpm ModelNumber : CLC-16-16-F NumberOfItems : 1 NumberOfPieces : 1 PartNumber : CLC-16-16-F ProductDescription : 'Rigid Shaft Coupling, 1 Piece Clamp, Inch, Bore Dia. 1 In., 1215 Lead Free Steel, Finish Black Oxide, Outside Dia. 1-3/4 In., Overall Length 3 In., With Keyway, Clearance Dia. 2.049 In., Screw Size 1/4 In.-28, Keyway Width 1/4 In., Max.
