Why Consider Metallic Belts for Your Application?
Engineers who specify metallic belts have possibilities to them that they do not have when using other products or components. Some essential features and benefits are talked about below.
HIGH STRENGTH-TO-WEIGHT RATIO:
This is an advantage in practically every application where high strength, light weight, or both are important.
DURABILITY:
Metal belts can withstand sustained contact with extremes of temperature, hostile environments, and vacuum. A number of alloys can be utilized, each with its own resistance to chemical substances, humidity, and corrosion. Engineers generally select a belt material based on physical properties, availability, and cost.
NO LUBRICATION:
Unlike the links of a chain, a metallic belt is an individual element and, therefore, does not generate any component friction that requires lubrication. This reduces program maintenance, increases reliability, and retains the system clean.
NONSTRETCHABLE:
Springtime steels with a higher modulus of elasticity make metallic belts virtually nonstretchable in comparison with additional belt types and chain. This makes them ideal in powerful applications for precision positioning.
SMOOTH OPERATION:
Metal belts are free from the pulsation of chordal actions often seen in other belt types and chain. This results in exact translation of the control system motion profile.
ACCURATE AND REPEATABLE:
Metal timing belts could be fabricated with a pitch accuracy of ±0.0005 inches station to station. This high amount of precision is extremely important in developing indexing, positioning, or processing equipment.
Great THERMAL AND ELECTRICAL CONDUCTIVITY:
Metal belts may transmit energy in the kind of heat, cold, and electricity.
NO STATIC BUILD-UP:
Steel belts discharge static electrical power, an essential capability in the manufacture of electronic components such as integrated circuits and surface area mount devices.
CLEAN:
Unlike HTD or toned neoprene belts, metallic belts usually do not generate particulate and so are ideal for food and pharmaceutical digesting.
CLEAN ROOM COMPATIBLE:
Metal belts usually do not require lubricants and will not generate dust that would introduce foreign substances into clean space environments. Additionally, they may be sterilized in an autoclave.
PRECISE CONSTRUCTION:
Edges are clean and measurements are tightly toleranced.
Steel conveyor belt pulleys are critical to the design of any automated conveyor belt system. They become the driving pressure behind the movement of the belt, producing torque and swiftness. 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 game with regards to pulleys. A steel belt is as good and specific as the pulleys. Many pulleys suggested by Ever-power are made from anodized aluminum (hard coating) with the right friction coefficient to operate a vehicle the metallic belt. Stainless steel may also be used nonetheless it is pricey and heavy, though it might 
be indicated using applications where extra hardness is necessary. If your application takes a lighter pulley, the professionals at Ever-power will help you select the best material.
Selecting the right pulley size and construction can have a substantial effect on the lifespan and performance of a conveyor belt. Ever-power engineers possess the data and experience to help you choose the appropriate pulley type, diameter, and composition to minimize maintenance downtime and maximize product volume.
Steel Conveyor Belt Pulley Types
Ever-power designs custom metallic conveyor belt pulleys and configurations to bring optimum efficiency to your system. While metallic conveyor belts are typically made of stainless, pulleys can be created from a number of materials, including aluminum or a number of plastic composites. Based on the unique requirements of your system, the pulleys can also be fitted with customized 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 used in the next 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 other complex belt paths
Steering smooth belts with an ISP is founded on the concept of changing tension human relationships across the width of the belt by adjusting the position of the pulley relative to the belt.
Rather than moving the pulley shaft left/right or up/down by pillow prevent adjustment, the ISP fits a adjustable steering collar and sealed bearing assembly to your body of the pulley.
The steering collar is designed with the skewed or an offset bore. When rotated, the collar changes the position of the pulley body, leading to controlled, bi-directional movement of the belt across the pulley face.
The ISP is exclusively available from Ever-power. It offers a simple method of steering flat steel belts. Users may combine ISP steering with the original belt tracking designs of crowning, flanging, and timing components to make a synergistic belt tracking system which effectively and specifically steers the belt to specified tracking parameters.
Unique Characteristics and Advantages of the ISP
· Toned belts are tracked quickly by rotating the steering collar.
· ISP designs minimize downtime when changing belts on creation machinery.
· ISP system is easy to use and needs simply no special tools or training.
· ISP simplifies the look and assembly of conveyor systems using flat belts.
· Existing idler pulleys may normally end up being retrofitted to an ISP without major system modifications.
· No maintenance is necessary 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 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 an individual pulley on the shaft.
· Is ALWAYS used when the pulley body can be a capped tube design.
· Is NEVER utilized when multiple pulleys are on a common shaft.
· Used selectively when the ISP is certainly a steering roll in a multiple pulley system.
Protected the ISP to the shaft using the split collar and locking screw included in the ISP. Rotate the shaft and collar as a device. 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 built into the ISP assembly. This method allows the belt to end up being tracked while running under tension.
Secure 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, 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 method enables the belt to become tracked while running under tension.
The Rotated Collar Method of ISP Flat Belt Tracking
· Used to individually modify each belt/pulley combination when there are multiple pulleys on a common shaft.
· Used when systems possess a cantilevered shafting typical of serpentine and additional complex belt path systems. It is recommended that these changes be made only once 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 acquired, secure the locking screw.

System Configuration
Number 1 1 – The drive pulley is a friction drive pulley.
· The ISP is definitely a friction-driven pulley. This configuration can be specified for a monitoring precision of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are attached to the pulley body to establish a lateral constraint. The steering feature of the ISP can be used to set one advantage of the belt against the flange with minimal side-loading to the belt.
System Configuration
#2 2 – The drive pulley is a timing pulley.
· The ISP is certainly a friction driven pulley. The teeth of the drive pulley and the perforations of the belt set up a lateral constraint. The steering feature of the ISP is utilized to minimize side-loading of the belt perforations. Tracking accuracy is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metallic belt systems.
OR
· The ISP is definitely a timing pulley. The teeth of the ISP and the perforations of the belt are used for precise tracking control of the belt with the steering feature of the ISP utilized 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 design can be utilized selectively on steel belt systems with lengthy center distances between pulleys and in applications where particulate accumulation on the top of pulley continually changes the tracking characteristic of the belt.
