sourcing map 12mm to 12mm Shaft Coupling 40mm Length 32mm Diameter Stepper Motor Coupler Aluminum Alloy Joint Connector for 3D Printer CNC Machine DIY Encoder

• Shaft Usage: 12mm to 12mm / 0.47 to 0.47 inch
• Material: Aluminum alloy; Size: 40x32mm/ 1.57x1.26inch( L*D)
• Feature: Screw type (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.

Description: 12mm to 12mm shaft usage diameter, 40mm length, 32mm 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: Screw type (coiling clamping) Size: 40x32mm/ 1.57x1.26inch( L*D) Material: Aluminum alloy Main Color: Silver tone Weight: 71g   Package Content: 1 x Shaft coupling
