About this item

  • Shaft Usage: 8mm to 8mm / 0.31 to 0.31 inch
  • Material: Aluminum alloy; Size: 25x18mm/ 0.98x0.71 inch( 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.


Description: 8mm to 8mm shaft usage diameter, 25mm length, 18mm 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: 25x18mm/ 0.98x0.71inch( L*D) Material: Aluminum alloy Main Color: Silver tone Weight: 26g Package Content: 2 x Shaft coupling

These couplings are very weak to torque. I sheared 2 of them on my z axis within 2 days of use.

I both currently use these and keep extras on hand. Occasionally my CNC mill will break one, but it's rare. I like this type because the will break before damaging my machine.
