Roller Conveyors in Gravity, Powered and Accumulation Types
Industrial suppliers requiring a 50-unit minimum order while unverified offshore factories disregard smaller orders entirely - leaving you with distributor markups tripling factory prices, or unknown suppliers shipping defective products with bent axles and flaking paint that fail within a week. When evaluating roller conveyor suppliers - including gravity roller conveyors, motorized roller conveying systems, and individually sourced conveyor rollers for maintenance or custom frame builds - check each factory's production capacity (10 to 10,000 units monthly), product range, workforce size (50 to 500+ workers), and years of operation before shortlisting.
That's the sourcing gap this directory closes. Order quantities over 20-30 units get 20-35% better prices and more responses. NDAs and an English-speaking account manager are free. There is no minimum order required on RFQ submissions, though it is up to each factory to accept or deny RFQ requests.
However, unless you inspect welds and roller alignment before committing, pricing alone won't protect you. Contact manufacturers directly to discuss specifications, or submit a request for quotation with roller diameter, frame material, load capacity, length, and motorized or gravity type to receive competing quotes.

Frequently Asked Questions
Where Can I Source Roller Conveyors From Verified Chinese Factories?
Factories listed for roller conveyors on Haizol typically respond to a direct inquiry within 24 hours, and every one was checked before being added to the directory. Contact the factory that matches your frame width and roller diameter directly, since it prices the job itself with nothing added on top. Ask them to confirm bearing type (6204 or 6205 series) and load rating with a safety factor built in. Haizol's account manager can also reach out to several factories at once if you want more than one quote.
How Do I Verify Steel Roller Quality?
Request 3-5 sample conveyor sections and inspect for axle straightness (within 0.5 mm runout), paint adhesion (cross-hatch method per ASTM D3359), and roller alignment under load. Ask for photos of welding fixtures and roller balancing equipment, since misaligned frames and unbalanced roller conveyor rollers cause vibration and jamming.
What Defects Should I Inspect on Roller Conveyors?
Check frame straightness (bow or twist beyond 2 mm over 1 meter length), roller spacing consistency (center-to-center distance on every fifth roller), and paint coverage on welds where rust starts. Spin each roller by hand to feel for roughness indicating bearing problems and watch for axle wobble during rotation.
How Do Steel Rollers Handle Load Requirements?
Specify load per roller in your RFQ and confirm bearing type (6204, 6205 series) with load rating using a 2x safety factor. Request bearing manufacturer specifications (SKF, NSK, or local equivalent) and details about their bearing press-fit process to prevent loose bearings causing noise and wobble.
What Are Roller Conveyor Lead Times?
Standard gravity roller conveyors with stock roller sizes ship in 10-15 business days after order confirmation. Motorized roller conveying systems take 3-5 weeks for motor integration (24V DC or 220V AC), electrical wiring, and load testing, plus 3-4 weeks for ocean freight or 7-10 days for air freight at 3-5x cost.
How Do I Protect Custom Roller Conveyor Designs?
Select the platform's standard digital NDA requiring signatures before file access, or upload your own custom NDA with specific IP protection language. For sensitive designs, submit an RFQ with only critical dimensions (overall length, width, roller diameter, load capacity) and share detailed drawings after reviewing quotes from your selected factory.
