Key Benefits
- Fits 50 mm or 60 mm diameter tubes with 1.5 mm or 2.3 mm wall thickness
- Supports shafts of 8 mm, 10 mm, or 12 mm for standard gravity roller applications
- Plastic housing with metal ball bearing ensures quiet and smooth operation
- Designed for use with steel, stainless steel, or PVC tubes in washdown or dry environments
- Preloaded precision bearing allows free rotation and consistent performance
Application Scenarios
- Gravity roller conveyors in warehouse loading zones where low noise and smooth operation are required
- Assembly lines using gravity rollers for part transfer between stations
- Washdown areas in food or pharmaceutical facilities where corrosion resistance is needed
- Conveyor sections where plastic end caps reduce wear on tube surfaces
- Applications requiring quick replacement of roller end caps without disassembling the entire roller
Who It Is For
- Conveyor system integrators building gravity roller lines
- Material handling equipment builders using standard roller components
- Industrial distributors stocking end caps by tube size and shaft diameter
- Manufacturers of gravity roller conveyors needing consistent end cap fit
- Logistics automation contractors installing low-maintenance roller systems
Problems It Solves
- Mismatched end caps that do not align with tube diameter or shaft size
- Noisy or binding rollers due to poor bearing fit or housing material
- Frequent replacement of end caps due to material wear or poor fit
- Inconsistent roller performance when using mixed components from different suppliers
- Lack of washdown-compatible end caps for wet or hygienic environments
Technical Features
- Plastic housing with integrated metal ball bearing for low friction rotation
- Available in two tube sizes: 50 mm and 60 mm with 1.5 mm or 2.3 mm wall thickness
- Shaft sizes of 8 mm, 10 mm, or 12 mm to match common roller shafts
- Precision bearing preloaded for consistent free rotation
- Housing designed to fit directly onto tube ends without additional machining
Materials
- Plastic housing material for corrosion resistance and low weight
- Nylon material used in housing for durability and wear resistance
- Steel or stainless steel ball for consistent bearing performance
- Suitable for use with steel, stainless steel, or PVC tubes
- Material choice supports washdown or dry environment applications
Quality Control
- Ball rotation tested by hand to ensure free movement
- Diameter and bore size verified against specified tube and shaft sizes
- Material grade confirmed against the model ordered
- No visible defects in plastic housing or bearing seat
Customization Options
- Special bore sizes available upon request for large volume orders
- Alternative shaft sizes possible with sufficient order quantity
- Material options for housing can be discussed based on application needs
- Custom labeling or packaging available for bulk buyers
Use Guide
- Match the tube diameter and wall thickness to the correct model number
- Ensure the shaft size (8 mm, 10 mm, or 12 mm) matches the roller shaft
- Install the end cap so the ball is fully seated and rotates freely
- Use stainless steel ball in wet or washdown environments
- Check alignment across multiple rollers to maintain consistent height
