Double pass brass universal adapter coupling 5mm x 5mm

Double Pass Brass Universal Adapter Coupling 5mm × 5mm

The Double Pass brass adapter coupling 5mm × 5mm offers stable rotational transfer for precision builds, supporting both motor shaft coupling layouts and engine shaft coupling configurations in compact mechanical systems. With its rigid brass structure, the coupling maintains smooth alignment when two equal-diameter shafts are seated accurately within the sleeve, ensuring reliable motion even in space-restricted assemblies.

Secure each shaft using the supplied M3 locking screws, which tighten evenly around the surface to minimize slip. This dependable interface enhances rotational consistency in prototype mechanisms, small drive modules, and applications where the motor shaft coupling needs long-term stability. With its strong grip and precision machining, the coupling performs effectively across various miniature drivetrain setups.
