Gravity Roller Conveyors for Packaging and Material Handling
These non-powered, low-friction conveyors move cartons, totes, and pallets through sorting, weighing, packaging, sealing, labeling, and palletizing. Modular sections enable reliable accumulation and gentle handling while cutting energy use and maintenance. Available in SUS304/316 stainless with IP65 options, the system integrates into turnkey lines for food, pharmaceutical, chemical, and agricultural products.
Core Advantages
Hygienic, durable build for demanding environments
Frames and rollers are available in SUS304/316 stainless steel. IP65 configurations support washdown. Materials align with FDA, HACCP, and GMP where required.
Fast installation, low maintenance, and quick changeover
Pre-engineered modules, adjustable H-stands, and tool-free roller replacement reduce downtime. Gravity operation removes motors and drives, lowering upkeep and enabling rapid SKU changeovers.
Flexible configurations for any layout
Combine straight, curved, and merge sections. Use extendable units to create dynamic lanes at docks and staging. Side guides, stops, and transfer plates keep products on track and transitions smooth.
Proven performance and rapid payback
By reducing manual handling and simplifying accumulation, these conveyors improve throughput and cut labor. They help maintain pass rates across inspection and packaging, supporting a fast return on investment.
Product Range and Options
Straight Roller Sections for general transport
Standard modules move cartons and totes efficiently. Select widths, roller diameters, and pitches to match load requirements. Butt joints and connectors ensure quick, accurate alignment.
Flexible Extendable Units for docks and e-commerce
Telescopic, height-adjustable sections expand to reach trailers or staging zones and compact for storage. Ideal for parcel, 3PL, and omnichannel fulfillment with changing lane lengths and angles.
Curves for smooth directional changes
Precision 30°, 45°, 60°, and 90° segments maintain orientation and flow. An optimized inner-radius pitch prevents hang-ups and supports consistent speed through turns.
Heavy-Duty for pallets and bulk loads
Large-diameter rollers, reinforced frames, and wider pitches handle pallets, drums, and heavy crates. Optional center supports and steel side rails increase stability.
Stainless Steel models for washdown areas
Corrosion-resistant frames, sealed bearings, and sanitary roller designs withstand caustic cleaners. Suitable for raw and packaged food, seafood, and chemical processing lines.
Gravity Roller Conveyors: Key Specifications
Dimensions and load capacity
Configure width, length, and load rating by selecting roller diameter and pitch. This balances footprint, ergonomics, and per-meter loading.
Widths and module lengths
Common clear widths: 300–1,200 mm (custom on request). Standard module lengths: 1,000–3,000 mm with joiners for longer runs. Heights adjust to match adjacent machinery.
Roller diameter and pitch
Typical roller diameters: 38, 50, 60, 76 mm. Use tighter pitch for smaller cartons and rigid support. Choose larger diameters for heavier loads to keep push force low.
Frame height and adjustable stands
Low-profile side frames fit tight spaces. H-stands provide fine height and slope adjustment for consistent gravity flow and safe ergonomics.
Materials and roller options
Choose galvanized steel, stainless steel, or PVC-coated rollers with precision bearings to balance durability, hygiene, and noise. End caps and labyrinth seals help protect bearings from ingress.
Bearings and noise performance
Low-friction sealed bearings reduce push force and sound levels. Optional quiet rollers and dampers support operator comfort.
Accessories and safety
Stops, inline brakes, side guides, and guard rails control flow and prevent overrun. Transfer plates and ball tables ease transitions at merges, scales, and labelers.
Flow control and protection
Friction inserts and gentle mechanical brakes regulate speed on slopes. End stops and toe guards enhance safety at accumulation points and workstations.
Applications and Use Cases
End-of-line accumulation and packing stations
Create ergonomic, low-energy buffers before case sealing, checkweighing, metal detection, and palletizing. Gravity sections protect downstream equipment.
E-commerce, fulfillment, and parcel handling
Ideal for cartons and totes at put-wall, sorter induction, and dock operations. Extendable units adapt to trailer positions and daily volume swings.
Food, pharmaceutical, chemical processing
Stainless, washdown-ready designs maintain hygiene when moving packaged goods between weighing, x-ray inspection, labeling, and cartoning.
Integration with Automated Lines
Upstream sorting and weighing integration
Pair with circular multi-weight sorters, linear or multihead weighers, and checkweighers to maintain steady infeed without powered drives.
Downstream packaging, labeling, and palletizing
Connect to VFFS baggers, carton droppers, labelers, case packing robots, and palletizing robots for continuous flow.
Installation, Operation, and Maintenance
Plug-and-play modules and quick line changes
Pre-drilled frames, standardized joiners, and adjustable supports reduce setup time. Sections reconfigure as product mix changes.
Safety and compliance
Slopes, endpoints, and guard positions are engineered for safe operation. Materials and finishes align with applicable FDA, HACCP, and GMP requirements.
Cleaning and preventative care
Smooth surfaces and tool-free roller swaps simplify cleaning. Periodic checks on bearings, fasteners, and guides maintain performance.
FAQs: Gravity Roller Conveyors
Q: How do I choose roller diameter and pitch?
A: Match diameter to load weight and base stiffness. Use tighter pitch for small cartons. Heavier loads benefit from larger diameters and robust frames.
Q: Can these conveyors handle irregular or soft-bottom packages?
A: Yes. Use tighter pitch, top covers, or transfer plates. For very irregular items, place products in trays or totes.
Q: What’s the difference between a roller conveyor and a skate wheel conveyor?
A: Roller conveyors offer broader load support and lower noise. Skate wheel types are lighter and suit uniform, rigid cartons with lower loads.
Q: Do you offer custom widths, curves, and stainless options?
A: Yes. Widths, radii, slopes, and materials (including SUS304/316) can be tailored to layout, hygiene needs, and load profiles.
