- Free running operation with low start-up torque and consistent speed
- Non-marking, corrosion-resistant construction suitable for sensitive surfaces
Materials
- Plastic housing for corrosion resistance and low noise
- Precision bearings integrated into the housing for smooth operation
- Hex shaft made of durable material compatible with standard tools
- Suitable for use on steel, stainless steel, and PVC tubes
Quality Control
- Each unit checked for free rotation and absence of binding
- Hex shaft dimension verified against 11 mm specification
- Tube diameter and wall thickness compatibility confirmed for the model
- Housing integrity tested under normal load conditions
Customization Options
- Special bore sizes available upon request for large volume orders
- Alternative wall thicknesses or shaft lengths may be considered with sufficient volume
- Custom model numbers available for specific tube diameter and shaft combinations
Use Guide
- Ensure the tube diameter is exactly 50 mm and wall thickness matches the model (1.2 mm, 1.5 mm, or 2.0 mm)
- Use a hex key to secure the shaft to the drive mechanism for consistent torque transfer
- Verify that the bearing rotates freely before mounting on the roller frame
- Avoid overloading beyond the intended load range to maintain bearing life
- Use in environments where corrosion or noise reduction is a priority

Compared With Other Options
| Metal roller bearings | Plastic housing reduces noise and prevents marking on sensitive surfaces, but may have lower load capacity than metal |
|---|---|
| Standard press-fit roller bearings | This unit is designed for specific tube sizes and shafts, ensuring consistent fit, while press-fit units may vary in alignment and runout |
| Roller bearings with round shafts | The hex shaft allows direct drive with standard tools, while round shafts require additional clamping or keying |
