uxcell 12mm to 12mm Shaft Coupling 30mm Length 25mm Diameter Stepper Motor Coupler Aluminum Alloy Joint Connector for 3D Printer CNC Machine DIY Encoder

Description:12mm to 12mm shaft usage diameter, 30mm length, 25mm diameter, set screw type, beam coupling.Zero backlash. One-piece metallic spring coupling. For little torque shaft connect.Absorption of parallel, angular misalignments and shaft end-play by spring action.Widely used in drive systems for encoders, instrumentation,lead screws, small pumps, feed rollers and anywhere light to medium duty, torsionally flexible coupling is required. Specification:Feature: Set screw (coiling clamping)Size: 30x25mm/ 1.18x0.98inch( L*D)Material: Aluminum alloyMain Color: Silver toneWeight: 29g Package Content:1 x Shaft coupling

• Shaft Usage: 12mm to 12mm / 0.47 to 0.47 inch
• Material: Aluminum alloy; Size: 30x25mm/ 1.18x0.98inch( L*D)
• Feature: Set screws (Coiling Clamping); Main Color: Silver tone
• Flexibility of coupling shaft removes stress between the motor and driving components.
• The shaft couplers are widely applied to small CNC machines encoding and 3D printers Z shaft coupling, simplifies the debugging difficulty.
