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 ExternallyAssignedProductIdentifier1 : 634529112243 ExternallyAssignedProductIdentifier2 : 0634529112243 ExternallyAssignedProductIdentifier3 : 00634529112243 ItemName : Ruland CLC-23-23-F 1215 Lead-Free Steel Rigid Coupling, One Piece with Keyway, 1.438" x 1.438" Bores, 2 5/8" OD, 3/8" x 3/8" Keyway, 3 7/8" Length ItemPackageDimensions_Height : 3.3 inches ItemPackageDimensions_Length : 4.5 inches ItemPackageDimensions_Width : 3 inches ItemPackageQuantity : 1 ItemTypeKeyword : beam-couplings Manufacturer : Ruland Manufacturing Co., Inc.
