Ruland Oldham couplings
Ruland’s Oldham Coupling is ideal for many light duty industrial and motion control applications, having the ability to protect more expensive machinery components. For example, the coupling can act as a torque limiter during overload. When the disk fails, the centre disc breaks cleanly and does not allow any transmission of power. Oldham couplings also have the advantage of electrical isolation due to the non-conductive nature of the centre disc. This prevents electrical currents from being passed to delicate instruments which can cause inaccurate data readings - an important consideration in medical applications for example.
