Belt Technologies has developed an innovative concept in flat belt tracking called the Independently Steerable Pulley, or ISP. It can be used in the following system designs: • Two pulley conveyor systems in which the ISP is the idler or driven pulley • Systems with multiple idler pulleys on a common shaft • Systems with serpentine or other complex belt paths • Steering flat belts with an ISP – based on the concept of changing tension relationships across the width of the belt by adjusting the angle of the pulley relative to the belt Rather than moving the pulley shaft left/right or up/down by pillow block adjustment, our PureSteel® ISP fits a variable steering collar and sealed bearing assembly to the body of the pulley. The steering collar is designed with either a skewed or an offset bore. When rotated, the collar changes the angle of the pulley body, resulting in controlled, bi-directional movement of the belt across the pulley face. The PureSteel®ISP is exclusively available from Belt Technologies. It provides a simple method of steering flat metal belts. Users may combine ISP steering with the traditional belt tracking designs of crowning, flanging, and timing elements to create a synergistic belt tracking system which efficiently and precisely steers the belt to specified tracking parameters. Unique Characteristics and Advantages of the ISP • Flat belts are tracked quickly by rotating the steering collar ○ ISP designs minimize downtime when replacing belts on production machinery ○ ISP system is easy to use and requires no special tools or training ○ ISP simplifies the design and assembly of conveyor systems using flat belts
