Unique-Bargains

Unique-Bargains 6mm Universal Joint Coupler 5pcs 23x11mm

SKU CH-WM5J-AP5JN

Pack of five 6mm nickel-coated iron universal joints, 23x11mm, for torque transmission in corrosive settings

  • Size or dimensions23 × 11 mm / 0.91 in × 0.43 in (L*D)
  • 5 universal joints per pack for multiple installations
  • 6 mm to 6 mm bore fits matching shafts directly
  • Nickel-coated iron resists corrosion in damp settings
  • 23 x 11 mm compact size suits tight spaces
  • Transmits torque while allowing angular misalignment

5-Pack 6 mm Universal Joint Coupler

This set contains five nickel-coated iron universal joints that connect two 6 mm shafts. Each coupler measures 23 mm long by 11 mm in diameter and weighs 33 g. The M4 thread size allows secure fastening in steering shafts, robotics linkages or light-duty power transmission. Buyers needing a different bore size or a single unit should look elsewhere.

Nickel-Coated Iron for Corrosion Resistance

The nickel coating protects the iron body in damp or mildly corrosive environments without adding measurable friction. Because the joint is a simple mechanical coupling it draws no power and produces no audible noise during normal rotation. No lubrication interval or temperature limit is supplied by the manufacturer.

Replaces Worn or Fixed Shaft Couplings

These universal joints replace rigid couplings when angular misalignment must be accommodated between two 6 mm shafts. The upgrade is worthwhile when vibration or slight shaft offset causes premature wear on fixed connectors. They do not suit applications that require constant-velocity motion or high-speed precision balancing.

Questions about this item

How do I install the 6mm universal joint coupler and what step is often missed?

Slide each 6mm shaft into the 23mm long bore, then tighten the M4 set screws; the step often missed is securing both screws evenly so the joint stays aligned under torque.

What maintenance will the nickel-coated iron coupler need later?

Inspect the M4 set screws for loosening after vibration cycles and wipe the silver tone surface clean; the nickel coating resists corrosion so no lubrication is required.

What limit appears first when the 5-piece set runs under sustained load?

The 11mm diameter body and 33g mass limit continuous torque before the M4 threads or bore walls yield.
