- Shaft diameter of Φ8 mm for direct fit on standard roller shafts
- Integrated precision bearing for smooth and quiet operation
- Plastic and nylon housing for lightweight and corrosion-resistant performance
- Free-running design reduces energy loss and wear in gravity roller systems
Materials
- Plastic housing for lightweight and non-corrosive use
- Nylon construction for improved wear resistance and quiet operation
- Integrated precision bearing for long-term free running performance
Quality Control
- Fit check against Φ40 mm tube and Φ8 mm shaft dimensions
- Rotation test of the bearing to confirm free movement
- Visual inspection for material defects or molding inconsistencies
- Verification of correct model number and specification on each unit
Customization Options
- Special bore sizes available upon request for large quantity orders
- Alternative wall thickness or tube diameter options possible with volume commitment
- Material variants may be considered based on application needs and order volume
Use Guide
- Verify that the roller tube is Φ40 mm with 1.5 mm or 2.3 mm wall thickness
- Confirm the shaft diameter is Φ8 mm before installation
- Ensure the end cap rotates freely on the shaft after mounting
- Use the correct model number (KTR-40X1.5-8 or KTR-40X2.3-8) based on wall thickness
- Replace worn or damaged end caps to maintain smooth roller operation
