A wide range of torque limiter couplings Mayr EAS-NC with ratchet (after 15 degrees) and synchronous (after one full turn) automatic re-engagement mechanism. Precise transmission of power parameters between the driven and driving axes, instantaneous load disconnection response when the set limits are reached, simple adjustment on the adjustment scale, maintenance-free construction concept.
The universal EAS-NC range can be used in a wide variety of industries, eliminating downtime and economic costs if equipment is damaged as a result of overload. Thanks to their optimized design, they are ready to work in extreme conditions. The functional parts are reinforced and hardened to ensure maximum resistance to mechanical wear.
Technical characteristics of the Mayr EAS-NC couplings
- Nom. moment: 0.65 - 2400 Nm;
- Max. speed: 300 - 4000 rpm;
- Outer diameter: 45 - 220 mm;
- Shaft/Sleeve diameter: 6 - 90 mm.
