The 1-3/4" x 1-3/4" Steel (Black Oxide) Two-Piece Clamp Rigid Shaft Coupling with Keyway - Low Profile is a precision-engineered coupling designed to connect aligned shafts and make them function as a single unit with zero backlash. Its two-piece clamp design simplifies installation, removal, and repositioning without the need to disassemble surrounding components, while the standard keyway adds greater torque capacity and fixed shaft phasing for accurate shaft synchronization. Made from black oxide steel, it offers strength, durability, and reliable performance. The Low Profile design features a clamp screw that protrudes beyond the outside diameter (OD), providing a compact shaft connection solution. With a straight-through bore, it is ideal for automation systems, motion control equipment, machinery assemblies, and industrial applications requiring precise alignment and dependable power transmission. This product is offered in High Strength and Low Profile styles and available in steel, stainless steel, and aluminum.
