Washdown-Ready Stainless Steel Sprocket Rollers for CDLR

We engineer our stainless CDLR rollers to provide massive torque handling without compromising sanitary compliance:

100% Stainless Washdown Integrity: We do not use plated carbon steel sprockets that will eventually rust. Every external metal component is pure austenitic stainless steel, rendering the entire assembly immune to water, humidity, and chemical sanitizers.

Precision TIG-Welded Sprockets: Heavy pallets create massive rotational torque. Our double sprockets are CNC-machined for flawless chain engagement and permanently TIG-welded (or mechanically pressed and pinned) to the tube head, ensuring they will never slip or shear under heavy load.

Hermetic Bearing Sealing: High-pressure water jets easily destroy standard bearings. We utilize specialized food-grade polymer (POM) or stainless steel end-housings combined with labyrinth seals to block liquid ingress, protecting the internal precision stainless bearings.

Heavy-Walled Load Capacity: Transporting a 2,000 lb pallet requires extreme structural rigidity. We utilize stainless steel tubing with wall thicknesses ranging from 1.5mm up to 3.0mm to prevent roller deflection and ensure perfectly level pallet travel.

Why Choose AstraRoll?

1. Exact Chain-Line Alignment

In CDLR systems, if the sprockets on adjacent rollers are misaligned by even a fraction of an inch, the chain will bind, snap, or wear prematurely. AstraRoll utilizes advanced CNC fixturing during the welding process to guarantee that the sprockets are perfectly true to the shaft and aligned to your exact "A" and "B" chain-line dimensions.

2. The 100% Stainless Promise

Many competitors weld cheap carbon steel sprockets onto stainless tubes, calling it a 'stainless roller.' In a washdown environment, the sprocket quickly rusts, destroys your drive chain, and contaminates your food zone. AstroRoll guarantees that the tube, the sprocket, the shaft, and the bearing housing are 100% forged from 304 or 316L stainless steel, providing absolute immunity to sanitation chemicals.

Frequently Asked Questions (FAQs)

Q: Do I need a Double Sprocket or a Single Sprocket roller?
A: If your conveyor uses a roll-to-roll drive configuration (where a short chain connects roller 1 to roller 2, another chain connects roller 2 to roller 3, etc.), you need a Double Sprocket. If your conveyor uses a single, long continuous chain that drags tangentially across the bottom or side of all the rollers, you need a Single Sprocket.

Q: Are the bearings inside the roller also made of stainless steel?
A: Yes. For our washdown-ready series, we utilize 440C or SUS304 stainless steel precision ball bearings. This ensures that even if microscopic amounts of moisture manage to bypass the external labyrinth seals over years of high-pressure cleaning, the internal rolling elements will not rust and seize.

Q: How do these rollers mount into the conveyor frame?
A: The most common and secure method for heavy CDLR systems is a Female Threaded shaft (e.g., M8 or M10 internal threads). You place the roller between the frames and bolt it tightly from the outside. We can also provide Spring-Loaded Hex shafts (e.g., 11mm or 7/16" Hex) if you require tool-less, rapid drop-in installation.

Q1. Are you a trader or direct factory?

We are a direct manufacturing factory with over 20 years of expertise in high-end industrial rollers, casters and material handling solutions. Our facility operates with ISO-certified quality management systems, allowing us to maintain full control over production cycles and quality standards.
