Technical data Coupling Handling

Roller chain coupling stainless steel series available

  • 1. When using the oil seal on a case, fit the oil seal onto either the left or right sprocket with the lip of the seal facing the teeth.
    (If installing vertically, install the oil seal on the upper sprocket.)オイルシール, スプロケット
  • 2. The side of the sprocket is brought into tight contact with the sprocket, correcting the Angular Misalignment and eccentricity.
    角度誤差

    Correct the angle so that the tooth side length T is equal around the circumference.
    Allowable declination angle (Angular Misalignment) θ = 1° or less

    平行誤差

    Place something straight against tooth root to ensure there is no misalignment at tooth root.
    Allowable eccentricity (parallelism error) ε = 2% or less of chain pitch (see values in the table below)

  • 3. Adjust the distance between both sprockets to dimension S (see dimension table), and secure the sprockets in place with the set screws.スプロケットをセットスクリューで固定
  • 4. Apply grease to the S-size area between both sprockets and also to the teeth.
    Next, apply grease to the chain and wrap it around the sprocket, leaving the distance between the sprockets (dimension S in the dimension table) and then install it. Wrap the chain around the sprocket. Insert the joint link into single strand.
    Insert the two intermediate plates. Insert the joint link into the second row of the chain. Insert the outer plate into the joint link that protrudes from the chain and attach spring clip.

  • 5. If using a case, apply the required amount of grease to both sides of the case and securely attach both cases to the sprocket with the bolts. There may be a small amount of grease leaking at the beginning of operation, but this will soon stabilize. If the leak does not stop, check that there are no problems with the installation.
