Double O Groove Taper Roller
The 05C2R5020/D2-12 is a double O groove gravity roller with a plastic end cap, designed for use in gravity roller conveyors where consistent tube diameter and shaft size are required. It features a precision bearing housed in a nylon and PP bearing house, and is available with steel, SUS304, or galvanized tube material with options for chrome plating, PU, or rubber coating. The roller has a taper degree of 3.6, a small end diameter of 50 mm, a big end diameter of D2, and a length of 11 mm with a width of W=11 mm. It is mounted on a 12 mm shaft and has a 2.0 mm thickness.

Key Benefits
- Double O groove design allows for consistent alignment on a 12 mm shaft and 50 mm tube diameter
- Precision bearing in nylon and PP housing reduces friction and supports smooth rotation
- Plastic end cap protects the bearing and prevents dust ingress
- Available with multiple surface treatments including chrome plating, PU, and rubber coating for different environmental needs
- Taper degree of 3.6 ensures even load distribution across the roller surface
Application Scenarios
- Gravity roller conveyors in warehouse loading zones where consistent tube and shaft dimensions are required
- Assembly lines where a roller must run on a 12 mm shaft and fit a 50 mm tube diameter
- Material handling systems where dust or debris must be kept out of the bearing area
- Conveyor sections requiring low rolling resistance and consistent performance over time
- Applications where the roller surface must be protected from wear using PU or rubber coating
Who It Is For
- Conveyor system integrators building gravity roller lines with consistent tube and shaft specifications
- Material handling equipment builders needing rollers that match existing tube and shaft dimensions
- Industrial distributors sourcing rollers in volume with fixed shaft and tube sizes
- Assembly line builders requiring reliable, low-maintenance rollers for continuous operation
- Warehouse and logistics automation contractors installing conveyors with standardised components
Problems It Solves
- Inconsistent roller fit on 12 mm shafts or 50 mm tubes due to mismatched groove or taper design
- Bearing contamination from dust or moisture in industrial environments
- High rolling resistance caused by poor bearing housing or misaligned rollers
- Need for multiple suppliers to source rollers with matching shaft size, tube diameter and surface treatment
- Rollers that fail prematurely due to lack of protection at the end caps
Technical Features
- Double O groove design with 3.6 taper degree for stable shaft alignment
- Precision bearing housed in nylon and PP for low friction and durability
- Plastic end cap to seal the bearing and prevent contamination
- Available with steel, SUS304, or galvanized tube material for different environments
- Surface treatment options include chrome plating, PU coating, and rubber coating for wear and corrosion resistance
Materials
- Steel tube for general industrial use
- SUS304 stainless steel tube for corrosive or washdown environments
- Galvanized tube for improved corrosion resistance
- Chrome plated surface for wear resistance and smooth operation
- PU coating for impact absorption and noise reduction
- Rubber coating for grip and vibration damping
Quality Control
- Taper degree verified to be 3.6 during machining
- Shaft fit checked on a 12 mm shaft to ensure smooth rotation
- Bearing rotation tested by hand for free movement
- End cap securely attached to prevent dust ingress
- Surface treatment inspected for uniformity and coverage
Customization Options
- Choose tube material: steel, SUS304, or galvanized
- Select surface treatment: chrome plating, PU coating, or rubber coating
- Specify end cap material if different from standard plastic
- Adjust length or width if required within the 11 mm standard
- Confirm taper degree and diameter match existing system requirements
Use Guide
- Ensure the 12 mm shaft matches the roller’s inner diameter for proper fit
- Verify the 50 mm tube diameter is consistent across all rollers in the line
- Use chrome plating or PU coating in high-wear or high-impact areas
- Choose SUS304 or galvanized tube for wet or corrosive environments
- Inspect end caps regularly to ensure they remain intact and sealed
