Key Characteristics of the Elastomer Jaw Couplings ECE 6518

Ringfeder ECE 6518 Elastomer Jaw Couplings are engineered for strong torque transmission, vibration damping and reliable performance in a wide range of industrial applications. Below are the core characteristics of this coupling series:

Cast iron housings, providing strong mechanical strength, long lifespan and stable operation under continuous load.
The elastomer spider (polyurethane) is designed for high flexibility, shock absorption and noise reduction — ensuring smooth power transmission.
Available in sizes 38–55 with hardness 92 Sh-A (Yellow spider)
and sizes 65–90 with hardness 98 Sh-A (Red spider) — suitable for different vibration levels and load conditions.
Manufactured according to precision fit standards, helping maintain stable alignment, reducing backlash and increasing overall coupling efficiency.

These characteristics make Ringfeder ECE 6518 a durable and dependable coupling solution for demanding industrial operations requiring high reliability.

Why Choose Ringfeder Elastomer Jaw Couplings ECE 6518?

The Ringfeder ECE 6518 is designed to deliver excellent performance in environments requiring strong torque transmission, vibration damping and stable mechanical alignment. With a working temperature range from –20°C to +120°C, the coupling ensures reliable operation even under variable thermal conditions.

Its elastomer spider absorbs shock loads, reduces vibration, protects bearings and gearbox, making it suitable for applications with frequent starts, stops or dynamic loading.

Typical industrial uses:

Water pumps, hydraulic pumps, vacuum pumps
Air compressors, blowers
Motor–gearbox connections
General power transmission systems with light to moderate misalignment

Thanks to its modular design, users can easily replace spiders or hubs without dismantling the entire system — reducing downtime and maintenance cost.
