The abrasion-resistant joining links replace the conventional pin/bore connection. This is why E6 and E6.1 are suitable for cleanroom applications. This has been confirmed by the IPA Fraunhofer Institute, ISO class 1 and 3 . The special design of the chain links and the small pitches are the reason why the E6 and E6.1 series are particularly quiet.
The new generation of smooth-running and cleanroom-suitable E6.1 series has extremely low-vibration, low-abrasion and is cost-effective.
Are you interested in the E6.1 series but would like to see it yourself first before making a final decision?
