your reliable partner Your advantages when using electromagnetically or pneumatically controllable torque limiting clutches with switching function: ❒ The clutches precisely limit the torque to the value determined by the supply current or air pressure and reduce damage, costly repairs and downtimes in case of overload. ❒ The clutches are remotely controllable by using current or air pressure as actuating or regulating mediums and can be included in complex control systems: a decisive advantage for usage in automated machinery. ❒ During operation the transmittable torque can be exactly...

your reliable partner The cyclic, pneumatically switchable and controllable torque limiting clutch EAS®-Sp ❒ Simple attachment of the drive elements ❒ Low mass moment of inertia ❒ Long service life and maintenance free ❒ High switch-off accuracy ❒ Integrated mechanically protected limit switch Integrated limit switch • Extremely short switch-off times Connection for control unit • In case of overload, the limit switch detects the axial disengaging movement of the control element quickly and precisely. • Motionless compressed air supply • ON/OFF switching function, multi-start function • The...

your reliable partner Application of the EAS®-Sp torque limiting clutch The backlash-free torque transmission: • In all kinds of automated machines • Balls in radially and axially arranged recesses on the hub and on the pressure flange. • With constantly changing operating conditions • The balls are pressed simultaneously into recesses of the hub and pressure flange, and therefore transmit the torques backlash-free in both rotational directions, also in case of reverse rotational direction. • With changing cycles and cycle speeds Use of the EAS®-Sp torque limiting clutch • In packaging...

O mayr your reliable partner Limit switch is included in the delivery. Technical Data The operating pressure of the clutch ranges between 1 and 6 bar; you can find the exact data in the diagram, page 8. We reserve the right to make dimensional and constructional alterations. 1) The speed for re-engagement or for synchronous switching operation depends on the mass to be accelerated and the load torque (see “Technical Explanations” page 8). 2) Size 5 not in stock 3) Mounting tolerance + 0.1 4) Without initiator guard bracket 5) Tolerance user-side H7 6) The position of the keyway to the...

Technical Explanations Operating speeds The speeds mentioned on pages 6 and 7 are operating speeds which refer to the engaged condition of the clutch. The re-engagement speed of the EAS®-Sp clutches depends on the corresponding clutch size or mass moments of inertia of the flanged drive element. Re-engagement or connection of the clutch under load should not take place. Please contact our application engineers regarding your special application. Torque adjustment Adjusting and altering the torques can be accomplished by altering the air pressure. The torque capacity is proportional to the...
