5-2) Installation of coupling
• Do not apply shock or excess axial load to the shaft when attaching the coupling. It may cause bearing damage or collar
may fall off.
• We recommend attachment by shrink fitting.
(1) When Using Coupling
Adjust the dimensions in Fig. 5 (A, B, and X) within the tolerance shown in Table 3.
(2) When Using with Chain Sprocket and Gear
• Make the tension angle of the chain perpendicular to the shaft.
• Refer to your catalog and other materials on chain for correct tension.
• Use sprocket and gears with pitch diameter at least three times of shaft diameter.
• Make the load point of sprocket and gear closer than the shaft center to the gearmotor or reducer side
(Refer to Fig. 6).
(3) When Using with V-belt
• Too much tension on v-belt will damage the shaft and bearing. Refer to your catalog and other materials on v-belt
for correct tension.
• Make the parallelism and eccentricity (b) between two pulleys 20' or smaller (Refer to Fig. 7.)
• Use the matched set with same circumferential length when using multiple v-belts.
