Conveyor rollers are used internationally and are a common requirement in just about every industry. Countries such as North and South America, Russia, China, Bulgaria, Japan, Finland, South Korea, Jerusalem (the list is endless), all have industries that use these rollers. Finding a reputable and honest supplier may be difficult, but it is not impossible. The ideal supplier will meet your application criteria and will work diligently to meet your particular specifications.

These type of conveyor rollers are used in aerospace, agriculture, automotive and heavy trucks, cement and aggregate, coal, oil, gas, construction, health, mining, machine tools, rail, wind energy towers and structures and waste to energy systems. The various constructs of these rollers are typically steel, stainless steel, aluminum and/or plastics. Ideally, these constructs will make high quality rollers to prevent untimely or everyday failures or shut-downs, thus avoiding unnecessary costs and slowdowns in production.

Steel conveyor rollers are often galvanized with the surface hardened, and possibly epoxy resin coated or coated with PU, PVC or rubber. Modular rollers can be driven on both sides and come in many variations. They can also come with electrical conductivity. Aluminum alloy and steel is a combination that is light weight, has high rigidity and is typically well anodized for resistance to corrosion. Whether these are used in metallurgy, mill, cement, sugar, oil or paper industries, the best will be low in frictional torque and big in high-speed rotation.

Many use a lubrication composition (filler between rows) that has a quality mixture of high molecular weight polyolefin and grease, which has been solidified, to reduce the number of contact portions between the lubricating composition (solid) and the outer rollers. This reduces excess heat and torque, making it more shock-resistant, while keeping things at a low rotating speed. It is imperative to keep the friction torque low, as this prevents slippage, keeping the rollers together and closer, thus decreasing the pulling tension.

The surface of rollers can wear over a period of time and resurfacing, rather than replacement is often recommended, if possible. This will decrease the consumption of power and allow for roller adjustment, which will most certainly lower operation costs. Resurfacing prevents higher stress conditions and hertz pressures that the wear will ultimately cause. Those who depend on these rollers count on them to be durable, low maintenance, cost-effective and dependable. Time and production are key elements in success and quality rollers will provide just that.
