Chain Coupling
The chain coupling is composed of double-strand roller chain and two sprockets, featuring a simple and compact structure that offers a exceptional flexibility and increased transmission capacity when compared to couplings of similar size.
Roller chain couplings boast a torque capacity surpassing the typical torque transmitted by shafts within the coupling’s bore range. Opt for the smallest coupling size capable of accommodating both shafts.
To ensure optimal service longevity, especially under high-speed or humid/abrasive conditions, its advisable to employ a cover. For effective lubrication, fill the space between the cover and the coupling with bearing grease of soft to medium consistency.
We supply couplings that are tested for ISO standard.
