Installation and Usage


  1. BREU-C series Cam Clutch couplings make use of BREU series Cam Clutch and CR type couplings without cover.
  2. Mount the clutch loosely on the high-speed shaft at first.
  3. Accurately align both sprockets by checking with a straight edgeon the teeth of both sprockets.
  4. Check whether the clearance(S) between the two sprockets is correct, then wrap the chain around the sprockets.
  5. Specify right hand (RH) or left hand (LH) as inner race overrunning direction from the view of cam clutch side (X) when ordering. See the above drawing.
  6. The same lubrication as for Tsubaki roller chain is necessary for the coupling chain.
  7. Ensure that the chain is properly closed with a connecting link and that the closed of the spring clip is installed in the same direction as the rotation of the outer race.
