Part of the Roller range, used in Warehouse and Distribution Centres.
Key Benefits
- Double sprocket design allows for positive chain drive on both sides of the roller
- Precision bearing in nylon and PP housing reduces friction and extends service life
- Available in steel or SUS304 tube material for different environmental conditions
- Surface treatments including galvanized, chrome plated, PU and rubber coating for wear and corrosion resistance
- Shaft size of ø12 mm matches standard industrial shafts and supports consistent drive alignment
Application Scenarios
- Chain-driven conveyor lines where positive drive is required on both sides of the roller
- Material handling systems in wet or corrosive environments using SUS304 with chrome plating or rubber coating
- Conveyor sections where surface wear must be minimized, using PU or rubber coated rollers
- Assembly lines requiring reliable chain engagement with low maintenance and consistent operation
- Industrial conveyors where the roller must support both load and drive function in a single component
Who It Is For
- Conveyor system integrators building chain-driven roller conveyors
- Material handling equipment builders needing dual sprocket drive rollers
- Warehouse and logistics automation contractors installing durable conveyor sections
- Industrial distributors stocking rollers with multiple surface treatment options
- Production line builders requiring consistent roller dimensions and drive compatibility
Problems It Solves
- Chain slippage on single sprocket rollers due to insufficient drive engagement
- Inconsistent drive alignment when using rollers with mismatched shaft sizes or bearing types
- Premature wear on conveyor rollers in harsh environments without proper surface treatment
- Difficulty in sourcing a roller that combines load support, chain drive and surface protection in one unit
- Need for multiple suppliers to source rollers with different materials, coatings and drive features
Technical Features
- Double sprocket design for positive chain drive on both sides
- Precision bearing housed in nylon and PP for low friction and long life
- Shaft diameter of ø12 mm for compatibility with standard drive shafts
- Roller length calculated as width plus 63 mm for consistent mounting
- Sprocket type 08B14T for standard chain engagement with common roller chain sizes
Materials
- Steel tube for general industrial use
- SUS304 tube for improved corrosion resistance in humid or chemical environments
- Galvanized surface treatment for increased rust resistance
- Chrome plated surface for wear resistance and smooth operation
- PU or rubber coating to protect the load surface and reduce noise
Quality Control
- Bearing rotation checked by hand for smooth operation
- Sprocket alignment verified to ensure chain engagement
- Surface treatment inspected for even coverage and adhesion
- Shaft diameter confirmed to be ø12 mm
- Roller length verified as width plus 63 mm
Customization Options
- Choice of tube material: steel or SUS304
- Selection of surface treatment: galvanized, chrome plated, PU or rubber coating
- Option to use the 02L2R6020-12 model with ø60*2.0 mm diameter and same shaft size
- Sprocket type 08B14T standard, but other types may be available on request
- Length adjusted to width plus 63 mm for consistent mounting across units
Use Guide
- Ensure the roller shaft diameter matches the existing shaft size of ø12 mm
- Verify that the roller length is width plus 63 mm to maintain consistent mounting
- Choose surface treatment based on environmental conditions and load surface requirements
- Use SUS304 tube and chrome plating in wet or corrosive areas
- Select PU or rubber coating to protect sensitive load surfaces and reduce noise
