- Production line builders needing quiet, low-friction end caps
Problems It Solves
- Inconsistent end caps that do not match tube diameter or shaft size
- Noisy operation from metal or poorly fitted end caps on plastic or thin-walled tubes
- End caps that bind or seize due to poor bearing fit or material mismatch
- Lack of standardization when sourcing end caps from multiple suppliers
- Frequent replacement due to premature wear from incompatible materials
Technical Features
- Precision 6002 bearing integrated into plastic housing
- Designed for 38 mm tube with 1.2 mm or 1.5 mm wall thickness
- Shaft diameter of 12 mm for standard roller shafts
- Plastic housing reduces weight and noise during operation
- Free-running design supports smooth product transfer without resistance
Materials
- Plastic housing for reduced noise and protection of tube surfaces
- 6002 precision bearing for consistent free rotation
- Compatible with steel, stainless steel, and PVC tubes
Quality Control
- Bearing rotation checked for free movement before packing
- Dimensions verified against 38 mm tube and 12 mm shaft tolerance
- Material consistency confirmed for plastic housing integrity
Customization Options
- Special bore sizes available upon request for large quantity orders
- End caps can be adapted for other tube diameters with sufficient volume
- Material options may be adjusted based on application needs
Use Guide
- Ensure the tube diameter is 38 mm and wall thickness is 1.2 mm or 1.5 mm
- Verify the shaft diameter is 12 mm before installation
- Install with the bearing seated fully in the housing to avoid binding
- Use in applications where noise reduction and smooth operation are required
- Avoid high impact or heavy shock loading beyond the intended use
