Metallic conveyor belt pulleys are critical to the design of any automated conveyor belt system. They act as the driving push behind the movement of the belt, producing torque and quickness. In very general conditions it can be stated 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 metal belt is only as good and exact as the pulleys. The majority of pulleys suggested by Ever-power are constructed with anodized aluminum (hard layer) with the right friction coefficient to drive the metallic belt. Stainless steel may also be used nonetheless it is costly and heavy, although it might be indicated in certain applications where extra hardness is essential. If your application takes a lighter pulley, the specialists at Ever-power can help you select the best material.
Selecting the correct pulley size and configuration can have a significant influence on the lifespan and performance of a conveyor belt. Ever-power engineers possess the knowledge and experience to assist you choose the appropriate pulley type, diameter, and composition to reduce maintenance downtime and maximize product volume.
Metal Conveyor Belt Pulley Types
Ever-power designs custom steel 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 created from a variety of materials, including aluminum or a variety of plastic composites. Based on the unique needs of your system, the pulleys can also be installed with customized timing attachments, relief channels, and more.
Independently Steerable Pulley
Ever-power has developed a forward thinking concept in toned belt tracking called the ISP (independently steerable pulley), which can be used in the next system designs:
· Two pulley conveyor systems in which the ISP may be the idler or driven pulley
· Systems with multiple idler pulleys on a common shaft
· Systems with serpentine or various other complex belt paths
Steering smooth belts with an ISP is based on the concept of changing tension romantic relationships across the width of the belt by adjusting the position of the pulley relative to the belt.
Instead of moving the pulley shaft still left/right or up/straight down by pillow prevent adjustment, the ISP fits a adjustable steering collar and sealed bearing assembly to the body of the pulley.
The steering collar was created with the skewed or an offset bore. When rotated, the collar changes the position of the pulley body, resulting in controlled, bi-directional motion of the belt across the pulley face.
The ISP is exclusively available from Ever-power. It offers a simple method of steering flat metallic belts. Users may combine ISP steering with the original belt tracking styles of crowning, flanging, and timing components to create a synergistic belt tracking 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 designs minimize downtime when changing belts on production machinery.
· ISP system is simple to use and requires no special tools or teaching.
· ISP simplifies the design and assembly of conveyor systems using toned belts.
· Existing idler pulleys can normally end up being retrofitted to an ISP without main system modifications.
· No maintenance is required once the belt tracking parameters have already been established.
· It prolongs belt life by minimizing side loading when working with flanges and timing pulleys.

Installation and Use
The ISP is mounted to the machine frame using commercially available pillow blocks. A clamp is used 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 certainly a capped tube design.
· Is NEVER used when multiple pulleys are on a common shaft.
· Used selectively when the ISP is a steering roll in a multiple pulley system.
Protected the ISP to the shaft using the split collar and locking screw built into the ISP. Rotate the shaft and collar as a unit. When the required tracking features are obtained, prevent the shaft from rotating by securing the shaft clamp. The pulley body will right now rotate about the bearing included in the ISP assembly. This technique enables the belt to end up being tracked while running under tension.
Protected the ISP to the shaft using the split training collar and locking screw included in the ISP. Rotate the shaft and collar as a device. When the desired tracking characteristics are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will at this point rotate about the bearing built into the ISP assembly. This technique enables the belt to be tracked while working under tension.
The Rotated Collar Approach to ISP Flat Belt Tracking
· Used to individually modify each belt/pulley combination whenever there are multiple pulleys on a common shaft.
· Utilized when systems possess a cantilevered shafting typical of serpentine and other complex belt path systems. It is recommended that these adjustments be made only when the belt is at 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.

System Configuration
#1 1 – The drive pulley is a friction drive pulley.
· The ISP is certainly a friction-driven pulley. This configuration is specified for a monitoring accuracy of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are mounted on the pulley body to establish a lateral constraint. The steering feature of the ISP is utilized to set one edge 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 can be a friction driven pulley. One’s teeth of the drive pulley and the perforations of the belt set up a lateral constraint. The steering feature of the ISP is used to reduce side-loading of the belt perforations. Tracking precision is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metal belt systems.
OR
· The ISP is a timing pulley. The teeth of the ISP and the perforations of the belt are utilized for precise monitoring control of the belt with the steering feature of the ISP used to minimize side loading of belt perforations. Again, tracking accuracy can be 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Notice: Although it is generally not recommended to have timing elements in both drive and driven pulleys, this style can be used selectively on metallic belt systems with long middle distances between pulleys and in applications where particulate accumulation on the top of pulley consistently changes the tracking feature of the belt.
