Technical Data  Coupling  Lubrication

Roller chain coupling  Lubrication

There are three lubrication systems for chain couplings. The system to use depends on operating rotation speed. (See the transmission capacity table. )

  • Lubrication method I...Apply grease regularly on a monthly basis.
  • Lubrication method II...Apply grease regularly on a weekly basis, or mount the casing filled with grease.
  • Lubrication method III...Mount the casing filled with grease.

When using lubrication type III, use a grease with high mechanical stability and good lubrication performance since the centrifugal force will make it stick to the inner surface of the case, tending to degrade the lubrication performance. The grease brands below are recommended.

The amounts of grease to use (specified amounts) are shown in the table on the bottom-right.

Grease change interval for lubrication type Ⅲ
Usage conditions Grease change interval
First change Change interval after first change
Operation at half or more of the maximum rotation speed 1000 hours 2000 hours
Operation at up to half of the maximum rotation speed 2000 hours 4000 hours

When the amounts below are applied, a small amount of grease leakage will occur at the start of operation but will soon stabilize.
