- Electrical parts manufacturing with sensitive components requiring low vibration
Who It Is For
- Conveyor system integrators building gravity roller lines
- Material handling equipment builders using plastic roller bearings
- Industrial distributors stocking roller components by tube and shaft size
- Production line builders needing consistent roller bearings for multiple units
- Manufacturers of gravity rollers, sprocket rollers, and O-belt rollers
Problems It Solves
- Inconsistent roller performance when using mismatched or non-standard bearings
- Noise and vibration from metal bearings in sensitive or indoor environments
- Corrosion issues in washdown or humid areas with metal components
- Difficulty in sourcing bearings that match specific tube and shaft dimensions
- Need for a single supplier for integrated roller components with consistent fit
Technical Features
- Plastic housing with precision molded inner race for consistent fit
- Bearing type 6001 integrated into the housing for smooth rotation
- Designed for 32 mm tube diameter with 1.0 mm or 1.2 mm wall thickness
- Shaft diameter options of 8 mm or 10 mm to match standard roller shafts
- Free running design with low friction for easy product movement
Materials
- Plastic housing for corrosion resistance and low weight
- Plastic inner race to reduce friction and noise
- Compatible with steel, stainless steel, and PVC tubes
- Suitable for environments requiring washdown or clean operation
Quality Control
- Bore size checked against 8 mm or 10 mm shaft tolerance
- Rotation tested by hand to confirm free movement
- Material grade verified against plastic housing and inner race specification
- Fit tested on 32 mm tube with 1.0 mm or 1.2 mm wall thickness
- Visual inspection for molding defects or flash
Customization Options
- Special bore sizes available upon request for large volume orders
- Alternative wall thicknesses or tube diameters can be discussed for bulk production
- Material options for housing or inner race may be considered for high volume
- Custom model numbering available for long-term supply agreements
Use Guide
- Verify tube diameter is 32 mm and wall thickness is 1.0 mm or 1.2 mm before installation
- Ensure shaft diameter matches 8 mm or 10 mm as specified in the model
- Check that the bearing rotates freely before mounting on the roller
- Use in environments where plastic material performance meets operational needs
- For high volume applications, confirm custom bore sizes are available before ordering

Compared With Other Options
| Metal roller bearings | Plastic bearings are lighter, quieter, and resist corrosion in washdown areas, but may have lower load capacity |
|---|---|
| Standard press-fit bearings | Integrated plastic housing allows direct mounting on tube without additional fittings, but may be less replaceable than metal units |
| Standard plastic end caps | Plastic roller bearings include a precision bearing, while end caps without bearings require separate shafts and may not rotate freely |
