- Production line builders requiring reliable shaft support in roller systems
- Manufacturers of gravity roller conveyors for medium to heavy load applications
Problems It Solves
- Shaft misalignment in gravity rollers due to loose or poorly fitting end caps
- Premature bearing wear caused by end cap deformation under repeated load
- Inconsistent roller rotation when end caps do not securely hold the shaft
- Difficulty in maintaining alignment across multiple rollers in a line
- Need for a single supplier for end caps matching specific tube and shaft dimensions
Technical Features
- Metal housing designed to withstand repeated loading and impact
- Precise internal bore matches shaft diameter of 20 mm for secure fit
- Outer diameter sized to fit inside a 76 mm tube with 3.0 mm wall thickness
- Housing retains the roller bearing and maintains shaft alignment
- Constructed for long-term use in industrial environments without deformation
Materials
- Metal housing for strength and resistance to deformation under load
- Designed for use with steel, stainless steel, or PVC tubes
- Suitable for environments with moderate to high mechanical stress
Quality Control
- Dimensional check of internal bore against 20 mm shaft diameter
- Verification of outer diameter to fit 76 mm tube with 3.0 mm wall thickness
- Visual inspection for burrs or surface defects that could affect bearing fit
- Sample testing of assembled rollers for smooth shaft rotation
- Final inspection before packing to ensure no damage or deformation
Customization Options
- Special bore sizes available upon request for large quantity orders
- Alternative material options may be considered for specific applications
- Custom length or flange design possible with sufficient volume commitment
Use Guide
- Ensure the tube diameter is 76 mm and wall thickness is 3.0 mm before installation
- Verify that the shaft diameter is exactly 20 mm to match the bore
- Install the end cap so the shaft is fully seated and the bearing is properly retained
- Use consistent end caps across all rollers in a line to maintain alignment
- Inspect for wear or deformation after prolonged use, especially in high-load areas
