    Timing PulleyHTD 8M timing belt idlers, suitable for MISUMI HTD 8M timing belts.

    Example of Use

    Example of Use
    ■Timing Pulley Mechanism name
    Belt tension device (manual)

    ■Mechanism function
    1. Move the roller on the adjustment side, and tighten and fix it when the conveyor belt opens.
    2. For multiple driving applications, the engagement rate can be improved by setting the roller in the middle position.

    ■ Role of the timing belt idler
    1. The belt is tensioned by fixing the belt assembly distance with the timing belt idler
    and with the assistance of the urethane roller.
