The 3-3/16" Aluminum Two-Piece Clamp Shaft Collar - Low Profile is designed for secure shaft positioning on standard round shafts, thin-wall tubing, and split hub applications. Precision-machined from aluminum, it provides superior holding power over set-screw type collars while protecting shaft surfaces with its smooth bore design. The two-piece clamp construction allows complete disassembly and installation anywhere along the shaft for easy assembly and adjustment. The Low Profile style features a clamp screw that extends beyond the outside diameter (OD), while High Strength and Heavy Duty styles are available for different application requirements, with the Heavy Duty style providing up to twice the holding power.
