Chain Coupling
The chain coupling is composed of double-strand roller chain and two sprockets, featuring a simple and compact structure that offers a high flexibility and greater transmission capacity compared to similar sized coupling.
Roller chain couplings have a torque capacity in excess of the torque normally transmitted by shafting which falls within the coupling bore range. Select the smallest coupling which will accommodate both shafts.
A cover should be used to assure maximum service life, particularly if the coupling operates at high speeds or under moist or abrasive conditions. For proper lubrication, fill the space between the cover and the coupling with soft to medium consistency bearing grease.
We stock TransDrive Power Transmission and Power Transmission couplings that are tested for ISO standard.
Components
Straight Bore Sprockets & Duplex Roller Chains
The coupling includes a pair of sprockets, one for each shaft being connected. Chain couplings also include Duplex Roller Chains, which are used to connect the two sprockets.

Lubrication
There are three methods to lubricate:
- Greasing Monthly
- Greasing Weekly or fill grease in the attached casing
- Fill grease in the attached casing.
Note
When attaching the casing, use high-quality grease because the grease is pressed to the inside wall of the casing due to centrifugal force, deteriorating lubricating ability of the grease. It is recommended to change the grease periodically to maintain high performance and durability of the coupling.
| Grease change intervals (with casing attached) | ||
|---|---|---|
| Operating Conditions | First Change | 2nd and later changes |
| Operating at 1/2 max speed or higher | 1000 hours | 2000 hours |
| Operating at 1/2 max speed or Lower | 2000 Hours | 4000 Hours |
Allowable errors
x = 2% or less of pitch of roller chain used
n = 1 or less
In case of high speed operation, shaft deviation and misalignment must be 1/2 allowable errors.
