R1900
RONWIN
HS Code: 8431390000
The R1900 Series is specifically designed for industries where moisture, corrosion, and stringent hygiene are daily challenges. By utilizing advanced polymer components and industrial-grade materials, these rollers provide a reliable, stable, and low-maintenance conveying solution that outperforms traditional steel rollers in corrosive applications.

The core roller tube is constructed from industrial PVC, offering excellent chemical stability. It withstands exposure to water, most acids, and alkalis, eliminating the risk of rust and corrosion that plagues steel rollers.
Significantly lighter than equivalent steel rollers, the R1900 series reduces the overall weight of your conveyor system. This leads to easier installation, lower energy consumption for operation, and less strain on system frameworks.
Experience a quieter working environment. The PVC material naturally dampens vibration and noise during operation, while also providing superior shock absorption to protect both your products and the conveyor system from impact damage.
The non-porous, smooth surface of the PVC tube prevents material buildup and allows for quick and easy cleaning. This makes them an ideal choice for food processing, packaging, and pharmaceutical industries where sanitation is critical.
For complete corrosion protection, key components are made from specialized polymers. The inner and outer bearing flanges are precision-made from POM, and the bearings themselves use stainless steel balls, ensuring long-lasting, maintenance-free performance even in wet and chemically aggressive environments.

Roller Tube: Industrial PVC
Bearing Flanges: POM (Polyoxymethylene)
Ball Bearings: Polymer housing with Stainless Steel balls
While PVC rollers have a lower load capacity compared to steel rollers of the same diameter, their unique advantages in corrosion resistance, weight reduction, noise control, and hygiene make them the intelligent and cost-effective choice for specific demanding applications.
Ideal For Industries:
Food & Beverage Processing
Chemical & Pharmaceutical Manufacturing
Packaging and Bottling Lines
Logistics & Warehousing (high-humidity environments)
Wastewater Treatment & Recycling Facilities
Any application requiring frequent wash-downs
Upgrade to a Corrosion-Resistant Conveying Solution.

This series of conveyor roller is especial for some industry which required roller should be waterproof, rustproof and anti corrode from acid and alkaline. The roller pipe is made of industrial PVC tube with good chemical stability, and it is much ligher than steel pipe roller with good stability. Other components adopts polymer ball bearing, the inner/outer flange of bearing is made of POM, the ball is made of stainless steel. The load capacity of PVC tube is much lower than the steel tube of the same diameter, but is has the advantages of low noise, well shockproof, light weight, croosion resistance and easy cleaning.
