Roller OverviewThe document provides an overview of
conveyor rollers, emphasizing the importance of selecting the appropriate roller type based on environmental conditions and product characteristics. It highlights that plastic components are fragile at low temperatures and that polyurethane may not be suitable for transporting colored packages. Products with hard, flat surfaces are ideal for
roller conveyors, while those with soft or irregular bottoms are not.
Conveyor Roller SelectionConveyor rollers are categorized into different conveying modes: gravity conveying, driven conveying, and accumulating conveying. Each mode is associated with specific roller series, such as the 1200 series for polymer bearing housing and the 1100 and 1800 series for steel bearing housing. The document emphasizes selecting the correct roller pitch to ensure steady conveying, recommending a minimum of three rollers to support goods at any moment.
Load Capacity and Roller Pitch
The load capacity of each roller must not exceed its maximum static loading. Guidelines for roller pitch selection suggest using a pitch of 1/4 to 1/5 of the product length for steady conveying. It also advises on the deflection of flexible products and the pitch calculation for double sprocket conveyors.

Material Specifications
Nitrile Butadiene Rubber (NBR) is noted for its excellent resistance to oil, good abrasion and heat resistance, but has low elasticity, poor cold and ozone resistance, and low electrical insulation properties.
Conveying Efficiency
To improve conveying efficiency and eliminate slip, friction between contact surfaces can be increased using rubber lagging, which also protects the conveyed surface and reduces noise. Alternatively, PVC sleeving can be used, offering similar benefits with a shorter lead time and cost-effectiveness.
Surface Treatments
Thick chrome plating enhances component performance by improving hardness, abrasion, temperature, and corrosion resistance.
Roller Installation Methods
Various installation methods are discussed, including spring-loaded and bolt-fastened methods. The choice of method affects assembly complexity and load capacity. High-quality carbon structural steel is recommended for shafts, with antirust oil as the standard surface treatment.
Bearings
Bearings are crucial for roller reliability and lifespan. The C3 clearance is recommended for optimal dynamic performance. The RZ sealing method is advised for its low friction and effective dustproof performance.
Additional Design Information
Considerations for conveying goods include reducing roller pitch for stability, avoiding sudden movements, and ensuring anti-static designs. For humid environments, stainless steel or anti-corrosion materials are recommended.
