How to choose Chain

Points to check when selecting, with the values for this product (RF200-US-1).

  1. 1. Select a pitch that matches the sprocket

    This product: Pitch P 63.50 mm

    The pitch must match the tooth profile of the sprocket, and different pitches cannot be combined. Listed products range from 31.75 to 76.2 mm. Larger pitches increase power transmission capacity, but they also add mass and cause greater vibration and noise at high rotational speeds, so the choice should be based on both rotational speed and load.

  2. 2. Check the load against the maximum allowable tension

    This product: Maximum allowable tension 108 (11000) kN (kgf)

    This is the upper limit of tension that may be applied in actual use. Multiply the chain tension calculated from transmitted power and speed by a service factor that accounts for starting shock and load fluctuation, and confirm that the result is at or below this value. Listed products range from 39.2 to 151 kN, and heavy-duty types have higher values even at the same pitch.

  3. 3. The minimum tensile strength is the guaranteed breaking value

    This product: Minimum tensile strength 580 (59100) kN (kgf)

    The minimum tensile strength is the guaranteed breaking load, and listed products range from 149 to 853 kN. The average tensile strength is a higher mean value than this, so the minimum value is used for strength calculations. It is not used as the basis for working load, but is used to check the safety margin against overload.

  4. 4. Verify the inner link width against the tooth width

    This product: Inner link inner width W 38.10 mm

    The inner link width corresponds to the tooth width of the sprocket. Some heavy-duty types can use sprockets for standard roller chains, but there are cases where cast iron sprockets are not permitted, so the tooth width and material conditions must be checked together.

  5. 5. Check compatibility by roller diameter and pin diameter

    This product: Roller diameter R 39.68 mm

    The roller diameter relates to the tooth bottom shape, and the pin diameter relates to connecting links and wear life. In some cases, successor specifications cannot be connected to previous specifications, so when partially replacing or adding links to an existing chain, dimensions and connectability should be verified against the manufacturer's documentation.

  6. 6. Confirm link count and lead time conditions

    Types without offset links (half links) can only be used with an even number of links, and allowance for adjusting the center distance is required. Also, some large-size products are made to order or quoted on each request, so spare parts procurement timing should be included in planning.
