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: 3mm to 5mm shaft usage diameter, 25mm length, 20mm 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); Main Color: Silver tone Size: 25x20mm/ 0.98x0.79inch( L*D) Material: Aluminum alloy Main Color: Silver tone Weight: 20g  Package Content: 1 x Beam coupling
