For use in low-noise applications, each HDPE roller combines the strength of welded steel body with the non-stick properties of a high-density polyethylene sleeve.
HDPE Idler Rollers are cylindrical components used in conveyor belt systems, where they serve as support and guide elements for the moving belt. The key differentiator of these rollers is their shell material: HDPE (High-Density Polyethylene). This engineering plastic offers a unique set of properties that make it suitable for demanding industrial applications.
Key Aspects:
Excellent Wear Resistance & Low Friction: HDPE has an exceptionally low coefficient of friction. This reduces the sliding resistance between the roller and the conveyor belt, leading to:
• Superior Corrosion and Chemical Resistance: HDPE is virtually impervious to moisture, acids, alkalis, and most solvents.
• Non-Stick Surface & Hygienic: The smooth, non-porous surface of HDPE prevents material buildup (e.g., sticky powders, slurry) and is easy to clean.
Reduced Belt Wear: Extends the service life of the more expensive conveyor belt.
Lower Energy Consumption: Less power is required to drive the conveyor system.
A typical HDPE idler roller consists of:
Shell: The outer cylinder made from precision-machined HDPE.
Bearings: Sealed and greased ball bearings (often deep-groove) pressed into the HDPE shell or metal end-caps.
Shaft: A stationary metal axle (often stainless or galvanized steel) on which the roller assembly rotates.
Seals: High-quality labyrinth or contact seals to protect the bearings from dust, moisture, and contaminants, ensuring long service life.
