Metal conveyor belt pulleys are critical to the look of any automated conveyor belt system. They become the driving drive behind the motion of the belt, making torque and quickness. In very general conditions it can be said that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision is the name of the overall game when it comes to pulleys. A metallic belt is as good and exact as the pulleys. Many pulleys suggested by Ever-power are made of anodized aluminum (hard coating) with the right friction coefficient to operate a vehicle the metal belt. Stainless steel may also be used but it is expensive and heavy, although it might become indicated using applications where extra hardness is essential. If your application takes a lighter pulley, the experts at Ever-power can help you select the best material.
Selecting the correct pulley size and configuration can have a substantial influence on the lifespan and performance of a conveyor belt. Ever-power engineers possess the knowledge and experience to assist you choose the correct pulley type, diameter, and composition to minimize maintenance downtime and maximize product volume.
Metal Conveyor Belt Pulley Types
Ever-power designs custom metallic conveyor belt pulleys and configurations to bring maximum efficiency to one’s body. While metallic conveyor belts are typically made of stainless steel, pulleys can be produced from a variety of materials, including aluminum or a variety of plastic composites. According to the unique needs of your system, the pulleys can also be installed with custom timing attachments, relief stations, and more.
Independently Steerable Pulley
Ever-power has developed a forward thinking concept in flat belt tracking called the ISP (independently steerable pulley), which can be utilized in the following system designs:
· Two pulley conveyor systems where the ISP may be the idler or driven pulley
· Systems with multiple idler pulleys on a common shaft
· Systems with serpentine or additional complex belt paths
Steering flat belts with an ISP is based on the concept of changing tension human relationships across the width of the belt simply by adjusting the angle of the pulley in accordance with the belt.
Instead of moving the pulley shaft still left/right or up/straight down by pillow block adjustment, the ISP fits a variable steering collar and sealed bearing assembly to your body of the pulley.
The steering collar was created with the skewed or an offset bore. When rotated, the collar changes the angle of the pulley body, resulting in controlled, bi-directional motion of the belt over the pulley face.
The ISP is exclusively available from Ever-power. It provides a simple approach to steering flat metal belts. Users may combine ISP steering with the original belt tracking styles of crowning, flanging, and timing elements to create a synergistic belt monitoring system which efficiently and exactly 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 styles minimize downtime when replacing belts on production machinery.
· ISP system is easy to use and requires simply no special tools or teaching.
· ISP simplifies the look and assembly of conveyor systems using flat belts.
· Existing idler pulleys can normally end up being retrofitted to an ISP without major system modifications.
· No maintenance is required once the belt monitoring parameters have been established.
· It prolongs belt existence by minimizing aspect loading when working with flanges and timing pulleys.

Installation and Use
The ISP is mounted to the system frame using commercially available pillow blocks. A clamp is utilized to prevent the shaft from turning.
The Rotated Shaft Method of ISP Flat Belt Tracking
· Is used in combination with systems having a single pulley on the shaft.
· Is ALWAYS utilized when the pulley body is definitely a capped tube design.
· Is NEVER utilized when multiple pulleys are on a common shaft.
· Used selectively when the ISP is usually a steering roll in a multiple pulley program.
Secure the ISP to the shaft using the split training collar and locking screw built into the ISP. Rotate the shaft and collar as a device. When the required tracking characteristics are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will now rotate about the bearing included in the ISP assembly. This technique allows the belt to become tracked while operating under tension.
Secure the ISP to the shaft using the split training collar and locking screw built into the ISP. Rotate the shaft and collar as a unit. When the desired tracking features are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will today rotate about the bearing included in the ISP assembly. This method allows the belt to be tracked while operating under tension.
The Rotated Collar Approach to ISP Flat Belt Tracking
· Used to individually adapt each belt/pulley combination whenever there are multiple pulleys on a common shaft.
· Utilized when systems have a cantilevered shafting typical of serpentine and additional complex belt route systems. It is recommended that these modifications be made only when the belt reaches rest.
Fix the shaft via the shaft clamp, loosen the locking screw of the steering collar, and rotate the steering collar about the shaft. When the required belt tracking features are attained, secure the locking screw.
Which Design Is Right for You?

Ever-power may be the worldwide leader in the look and production of application-specific pulleys, steel belts, and drive tapes. Our products provide unique benefits for machinery used in precision positioning, timing, conveying, and automated production applications.
System Configuration
Number 1 1 – The drive pulley is a friction drive pulley.
· The ISP is usually a friction-driven pulley. This configuration is certainly specified for a tracking precision of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are attached to the pulley body to determine a lateral constraint. The steering feature of the ISP is used to set one advantage of the belt against the flange with reduced side-loading to the belt.
System Configuration
#2 2 – The drive pulley is a timing pulley.
· The ISP is a friction driven pulley. One’s teeth of the drive pulley and the perforations of the belt establish a lateral constraint. The steering feature of the ISP can be used to minimize side-loading of the belt perforations. Tracking accuracy is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metal belt systems.
OR
· The ISP is usually a timing pulley. One’s teeth of the ISP and the perforations of the belt are utilized for precise tracking control of the belt with the steering feature of the ISP used to minimize side loading of belt perforations. Again, tracking precision can be 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Note: Although it is generally not recommended to possess timing elements in both the drive and driven pulleys, this design can be utilized selectively on metallic belt systems with lengthy middle distances between pulleys and in applications where particulate accumulation on the top of pulley consistently changes the tracking feature of the belt.
