Roller chain coupling  Stainless steel series  Handling

  • 1. When using the coupling in the case, fit the oil seal onto the right or left sprocket with the seal’s lip oriented toward the teeth.
    (When using the coupling in a vertical orientation, attach the oil seal to the top sprocket. ) Oil seal , Sprocket
  • 2. Bring the sprocket side faces into contact with each other and correct their angular misalignment and parallel misalignment.
    Angular Misalignment

    Correct the angle so that tooth side face dimension T is equal around the circumference.
    Allowable angular misalignment θ = No more than 1°

    Parallel Misalignment

    Place a straight edge on the tooth bottoms and adjust to eliminate any misalignment between them
    Allowable parallel misalignment (Parallel Misalignment ) ε = No more than 2% of chain pitch (see values in table below )

  • 3. Separate the sprockets by a distance equal to dimension S (given in the table of dimensions), and fasten the sprockets in place with set screws. Fasten the sprockets in place with set screws.
  • 4. Fill the dimension S gap between the sprockets with grease, and also apply grease to the teeth.
    Apply grease to the chain next, then wrap the chain onto the sprockets. (Wrap the chain onto the sprockets while the sprockets are separated by the dimension S distance.) Insert the joint link into the first chain stands.
    Insert the two center plates. Insert the joint link into the second chain strand. Insert the outer plate into the joint link protruding from the chain, and attach the clip.

    Insert the outer plate into the joint link protruding from the chain, and attach the clip.
  • 5. If using the case, fill both sides of the case with the specified amount of grease, and use the bolts to firmly attach both sides of the case to the sprockets. A small amount of grease leakage will occur at the start of operation but will soon stabilize. If leakage doesn’t stop, check for attachment problems.
