Key Benefits
- Designed for 50 mm and 60 mm tube diameters with multiple wall thickness options
- Precision bearing ensures smooth, free-running operation with low friction
- Quiet operation suitable for environments where noise must be minimized
- Available with shaft sizes of 10 mm, 12 mm, and 14 mm to match existing roller shafts
- Plastic and nylon housing resists corrosion and is suitable for washdown environments
Application Scenarios
- Gravity roller systems in light to medium weight conveying lines in electrical parts manufacturing
- Assembly lines where quiet operation is required to avoid noise interference
- Warehouse loading and unloading stations using gravity rollers with plastic end covers
- Mould manufacturing lines where corrosion resistance is needed for frequent cleaning
- Conveyor sections handling medium weight parts where smooth, consistent rotation is critical
Who It Is For
- Conveyor system integrators building gravity roller lines with specific tube and shaft dimensions
- Material handling equipment builders sourcing consistent end covers for roller assemblies
- Industrial distributors stocking plastic end covers by tube diameter and shaft size
- Manufacturers of gravity rollers needing standardized end covers for production runs
Problems It Solves
- Mismatched end covers that do not fit standard tube diameters or shaft sizes
- Noisy or binding roller operation due to poor bearing fit or low-quality housing
- Corrosion in washdown environments when metal or non-resistant materials are used
- Inconsistent performance across a roller line due to variation in end cover quality
- Need to source end covers from multiple suppliers for different tube and shaft combinations
Technical Features
- Precision bearing integrated into the plastic housing for smooth rotation
- Housing made from plastic and nylon materials for lightweight and corrosion resistance
- Designed to fit 50 mm and 60 mm tube diameters with multiple wall thicknesses
- Available with shaft sizes of 10 mm, 12 mm, and 14 mm to match common roller shafts
- Free-running design reduces effort required to move loads on gravity conveyors
Materials
- Plastic housing for lightweight and corrosion-resistant performance
- Nylon housing for improved wear resistance and durability
- Precision bearing integrated into the housing for consistent rotation
- Suitable for use with steel, stainless steel, and PVC tubes
Quality Control
- Bearing fit checked for smooth rotation without binding
- Housing dimensions verified against tube and shaft specifications
- Material grade confirmed to match the plastic and nylon options ordered
Customization Options
- Special bore sizes available upon request for large quantity orders
- Custom wall thickness or shaft size options possible with sufficient volume
- Different model numbers available for different tube diameters and shaft combinations
Use Guide
- Verify tube diameter and wall thickness match the selected KTR model
- Confirm shaft size matches the required 10 mm, 12 mm, or 14 mm specification
- Ensure the bearing is free to rotate without resistance after installation
- Use in environments where corrosion resistance and quiet operation are required
- Select the correct model based on the roller tube size and shaft diameter
