Part of the Roller range, used in Warehouse and Distribution Centres.
Key Benefits
- Double sprocket design allows chain drive on both ends for balanced load transfer
- Steel or SUS304 tube material provides strength and durability in industrial environments
- Available with galvanized, chrome plated, or PU/rubber coating for corrosion resistance or surface protection
- Sprocket teeth match standard 08B, 10A chain sizes for direct compatibility with common drive systems
- Consistent shaft size and tube diameter allow for direct replacement in existing conveyor lines
Application Scenarios
- Chain-driven conveyors in warehouse automation where both ends require drive engagement
- Assembly lines using chain drives with multiple sprocket rollers for synchronized movement
- Heavy-duty material handling systems where consistent shaft alignment and load support are critical
- Conveyor sections requiring replacement of worn sprocket rollers without redesigning the drive system
- Systems using 08B or 10A chain drives where a double sprocket roller ensures even tension and alignment
Who It Is For
- Conveyor system integrators building chain-driven conveyor lines
- Industrial equipment builders requiring consistent sprocket roller replacements
- Logistics automation contractors installing or maintaining chain-driven transfer systems
- Production line builders using double sprocket rollers in powered conveyor sections
- Industrial distributors stocking sprocket rollers by tube diameter and shaft size
Problems It Solves
- Replacing sprocket rollers that are mismatched in shaft size or sprocket type across a conveyor line
- Chain misalignment caused by single sprocket rollers with inconsistent tooth engagement
- Wear and failure due to poor shaft support in rollers with weak bearing houses
- Inconsistent drive performance when sprocket rollers are not compatible with standard chain sizes
- Lack of surface protection in harsh environments where rollers are exposed to moisture or abrasion
Technical Features
- Double sprocket configuration with teeth on both ends for dual drive capability
- Steel or SUS304 tube material for strength and resistance to deformation under load
- Steel bearing house provides robust support for the shaft and bearings
- Sprocket teeth match 08B and 10A chain standards for direct compatibility
- Available with galvanized, chrome plated, or PU/rubber coating for environmental protection
Materials
- Steel tube and bearing house for general industrial use
- SUS304 stainless steel tube for corrosion resistance in wet or clean environments
- Galvanized surface for protection against rust in moderate environments
- Chrome plated surface for improved wear resistance and appearance
- PU or rubber coating for noise reduction and surface protection on the roller
Quality Control
- Sprocket tooth profile checked against 08B and 10A chain compatibility
- Shaft diameter verified to match the specified ø12, ø15, or ø20 mm
- Tube diameter and thickness confirmed against the model specification
- Surface treatment inspected for uniformity and coverage
- Roller length measured to ensure L = W + 63 mm or L = W + 69 mm as required
Customization Options
- Choose between steel or SUS304 tube material based on environmental conditions
- Select surface treatment: galvanized, chrome plated, or PU/rubber coating
- Select shaft size: ø12 mm, ø15 mm, or ø20 mm depending on bearing and drive requirements
- Select sprocket type: 08B9T, 08B11T, 08B14T, or 10A13T based on chain size and load
- Select roller length based on W + 63 mm or W + 69 mm as per design
Use Guide
- Ensure the shaft diameter matches the bearing size in your conveyor frame
- Verify that the sprocket type (08B or 10A) matches the chain used in the system
- Use galvanized or chrome plated finish in environments with moisture or wear
- Apply PU or rubber coating where noise reduction or surface protection is needed
- Confirm the roller length is L = W + 63 mm or L = W + 69 mm to fit the conveyor frame
