Unique-Bargains 5mm Rigid Shaft Coupling 22mm 14mm Silver 2 Pcs

SKU CH-4BX1-QZY3T

Connects two 5 mm shafts with a rigid 22 mm steel coupler and eight M4 screws for high-torque model or mechanical drives

  • Connects 5mm shafts with zero backlash for precise motion control
  • Steel construction delivers high torque capacity and low inertia
  • Eight M4 set screws lock both shafts securely in place
  • Compact 22mm length fits tight mechanical assemblies
  • Maintenance-free design resists oil and corrosion for long service life

Rigid Steel Coupler 5mm Bore

This pack contains two rigid shaft couplers machined from steel for low inertia and high torque transmission. Each coupler joins two 5mm shafts with an 180 degree through angle and an outside diameter of 14mm. They suit model cars, boats, moulds and general mechanical drives.

Installation Uses Eight M4 Screws

Each coupler is secured by eight M4 screws included in the package. Tighten evenly to avoid binding; the rigid design leaves no rotation gap so angular misalignment must be minimal. Allow 1 to 3mm variance from the listed 22mm length due to manual measurement.

For Precision Low-Inertia Drives

Builders needing a maintenance-free, oil-proof connection with zero backlash will benefit from the steel construction. Those requiring flexible misalignment compensation, larger bore sizes or non-metallic insulation should look at alternative coupling types.

Questions about this item

How can I confirm the 5mm rigid shaft coupling is aligned correctly after installation?

Check that the two shafts meet flush inside the 22mm length and that the 8 M4 screws are tightened evenly; the steel coupler should transmit torque without any rotational play.

What hardware is included with the two couplers?

The package contains two steel rigid shaft couplers measuring 22mm long by 14mm outside diameter and eight M4 set screws for securing each shaft.

Which bore size should I select for a 5mm motor shaft?

This coupling has a 5mm to 5mm bore, so it fits a 5mm shaft on both sides; choose this version only when both connected shafts are 5mm.
