tooloflife High-Speed Aluminum Clamp-On Coupling, 8-22mm Bore Shaft Connector for 3D Printer Z-Axis/CNC Equipment (D)

Feature:【Multiple Models】This rigid clamp-on coupling is available in five models, covering two outer diameters of 32 mm/1.26 in and 40 mm/1.57 in, with lengths ranging from 32 mm/1.26 in to 50 mm/1.97 in. with inner hole ranges from 8-16mm/0.31-0.63in to 10-22mm/0.39-0.86in, ensuring a suitable size for both thin and slightly thicker shafts.【Screw Locking Mechanism】This aluminum shaft coupling features a direct screw clamping design, ensuring a secure connection once locked, and preventing loosening during normal operation. Additionally, the screw head is recessed, with no protrusions on the surface, so there is no risk of bumping into or scratching hands during operation.【Hard and Rust-Resistant】The main body of this motor shaft coupler connector is made of lightweight aluminium alloy, which is lightweight and does not weigh down the equipment. Additionally, the surface has undergone anodised treatment, making it scratch-resistant and corrosion-resistant. It does not rust or darken over time, making maintenance simpler.【Stable Speed】The A, B, and C models have a maximum speed of 19,000 RPM, while the D and E models have a maximum speed of 15,000 RPM. Whether for precise operations on little CNC machines or rapid Z-axis movement on 3D printers, the product maintains a steady pace with smooth, vibration-free operation.【Easy Installation】This rigid clamp-on coupling​ includes single-section and double-section models. Single-section models can be installed in narrow spaces, while double-section models can be used when adjusting length or adapting to larger shaft spacings. Installation is simple and no-hassle.Specification:Material: Aluminium AlloySurface Treatment: AnodisedColour: Natural ColourModel: DDimensions: As ShownNote: Please allow for manual measurement errors and colour differences.Package Included:1 * Motor Shaft Coupler Connector
