FAQ
- This Gravity Conveyor Roller is made from high-quality stainless steel or galvanized carbon steel, ensuring a long-lasting and robust product that can withstand corrosion and wear in various industries.
- This roller is suitable for a wide range of industries, including machinery repair shops, manufacturing plants, food and beverage factories, farms, retail stores, food shops, construction sites, and others, making it a valuable addition to any facility.
- This roller is designed for easy integration into existing conveyor lines, minimizing downtime and hassle.
We can provide stainless gravity rollers with many types to be selected, which can meet various environment scenario requirements. In addition, we can also support customized services according to the customers' special needs for dimensions and performances.
There are a variety of specifications and models of gravity rollers, the following are some common ones' examples:
- Classified by diameter
Φ25mm: This diameter rollers are commonly used on light and medium-duty conveyor line, the length of tubes and shafts can be customized according to the specific requirements.
Φ32mm and Φ38mm: These two diameter rollers are commonly used on medium-duty conveyor line and dimensions can also can customized.
Φ50mm: This diameter rollers are suitable for the heavy-duty and largescale conveyor line and have strong carrying capacity and nice stability.
Φ60mm and above: This diameter rollers are commonly used on extra-heavy duty or special requirement conveyor line with specifications can be customized according to different use scenarios.
- Classified by material
Stainless steel rollers: Their features of corrosion and wear resistance and elegant appearance make them can be used widely on food, pharmaceutical and chemical industries and so on.
Galvanized rollers:Galvanizing the surfaces of the carbon steel rollers can improve the performances of corrosion resistance and service life and can be often used in the humid and corrosive environments.
- Classified by special requirements:
Gravity roller idlers: These rollers have no ability to drive and rely on the friction of the conveyor belt for rotation and are commonly used on the linear transportation section.
Dimension customized rollers: Customize suitable dimension roller according customers' special requirements, such as the width of the conveyor belts and the layout of the conveyor system and so on.
- Types and features:
Gravity rollers can be divided into horizontal plate, vertical plate and hybrid plate type. The horizontal plate type is mainly used for light cargo handling, carrying capacity is small; vertical one is mainly used for heavy cargo handling, carrying capacity is large; The horizontal and vertical hybrid one combines the advantages of the both and is suitable for cargo handling with different load requirements.
- The common specifications of gravity rollers include diameter, length, carrying capacity and so on. For example, the diameters of some kinds of gravity stainless steel rollers may be 25, 38, 50, 60, 76, 89, 110, 160 and 220mm, length falls between 100-2000mm and carrying capacities varies depending on the specific specification.
- Usage scenarios: Gravity rollers are widely used in areas such as conveyor lines, packing machinery, food machinery and so on and can provide stable supporting and transportation function in various transportation system.
In addition, the specification of gravity rollers may also involve several parameters such as shaft diameter, wall thickness, pipe length and total length, and the specific selection needs to be comprehensively considered according to the actual situation of the conveyor system.
