4-3. Determine Sprocket Locations

The diagrams below show the location and distance between sprockets (pitch) for each type of chain.

Find the percentage of maximum allowable load (maximum allowable load per 1 meter of chain width) that the tension per 1 meter of chain width F' derived by means of step 6 [formula (2)] represents.

Note that the locations and pitch may change depending on chain tension rate F1.

Formula of chain tension rate F1 (%)

F1 = 100F' A ...(3)

F'...Tension applied per 1 meter of chain width derived by step 6 kN/m{kgf/m}

A...Maximum allowable load per 1 meter of chain width with given temperature kN{kgf}

Refer to the allowable load graphs.

(1) WT0405-W

(2) WT0705-W

(3) BTN5, BTN5-A

Note) BT5-24T sprocket cannot be used with BTN5-A (with tab guide attachment). Please consider using BT5-32T. WT-SW1500-24T can also be used.

(7) WT1907-K

Note) If the chain width is an odd numbered inch, the mounting pitch will be 76.2 mm for each. Arrange the around the center portion for adjustment.

(8)BT6 Series, BTC8, BTC8-A

・Sprocket locations when chain tension rate (F1) is 50% or less

(9)BT6 Series, BTC8

・Sprocket locations when chain tension rate (F1) is greater than 50%

(10)BTC8-A

・Sprocket locations when chain tension rate (F1) is greater than 50%

(11)WT2505-K, WT2506-K, BTM8H

(12)WT2515-W, WT2515G-W, WT2515F-W

(13)WT2250FG、VG

(14)BTC8S, WT2525-K, WT2525VG-K

(15)WT2705-K/WT2706-K

Note)

1. Be sure to place sprockets at the * positions.
2. If the width is an odd numbered inch, the mounting pitch will have one irregular pitch. Arrange the around the center portion for adjustment.
