Plastic PVC Gravity Roller Conveyor
The THJR series is a plastic PVC gravity roller conveyor designed for light weight product conveying in indoor environments. Each unit has a roller diameter from 16 mm to 60 mm, with shaft sizes of 5 mm to 12 mm and lengths from 50 mm to 1200 mm. The rollers are made from PVC and are used in low load applications where smooth, quiet movement is required without power.
Product Overview
The THJR series is a plastic PVC gravity roller conveyor designed for light weight product conveying in indoor environments. Each unit has a roller diameter from 16 mm to 60 mm, with shaft sizes of 5 mm to 12 mm and lengths from 50 mm to 1200 mm. The rollers are made from PVC and are used in low load applications where smooth, quiet movement is required without power.
Part of the Roller Conveyor range, used in Warehouse and Distribution Centres.
Key Benefits
- Low weight product handling with smooth, quiet operation on PVC rollers
- Available in multiple diameters and shaft sizes to match existing tube and shaft dimensions
- Lengths from 50 mm to 1200 mm allow for flexible line design and integration
- PVC material resists dust and light moisture, suitable for indoor use
- Simple gravity-fed movement reduces energy and maintenance needs
Application Scenarios
- Light assembly lines for electronics or small components where product weight is under 5 kg
- Indoor product transfer between workstations in a clean room or factory floor
- Conveying small boxes, bottles or packaging in a warehouse or distribution center
- Integration into a larger conveyor system where low load zones require passive movement
- Short transfer sections where powered conveyors are not needed
Who It Is For
- Conveyor system integrators building low load indoor lines
- Material handling equipment builders using gravity rollers in light duty applications
- Industrial distributors stocking standard roller sizes by diameter and shaft
- Assembly line builders needing consistent roller dimensions for modular design
- Warehouse automation contractors installing short gravity sections
Problems It Solves
- Need for consistent roller diameter and shaft size when replacing or expanding a gravity conveyor
- Difficulty in sourcing a full range of light duty rollers from a single supplier
- Mismatched roller sizes when assembling conveyors from multiple vendors
- Noise and wear from metal rollers in low load indoor applications
- Lack of standard length options that fit existing frame spacing
Technical Features
- PVC rollers with specified diameter and tube thickness for consistent fit
- Shaft sizes from 5 mm to 12 mm to match common tube and shaft standards
- Roller lengths from 50 mm to 1200 mm for modular line construction
- Gravity-fed operation with no power required
- Smooth surface finish on PVC for quiet and consistent product movement
Materials
- PVC roller body for low weight, quiet operation and resistance to dust and light moisture
- Consistent PVC material across all models for uniform handling performance
- No metal components in the roller body to reduce noise and wear on light products
Quality Control
- Diameter and wall thickness measured against the specified tolerance
- Shaft size verified to match the model specification
- Length checked to ensure it falls within the stated range
- Visual inspection for surface defects or warping in the PVC
- Shaft alignment checked to prevent wobble during rotation
Customization Options
- Select model based on required roller diameter, shaft size and length
- Choose between available lengths within the 50 mm to 1200 mm range
- Select from the full range of models to match existing tube and shaft dimensions
- No options for material change beyond the standard PVC used in all models
Use Guide
- Match the roller diameter and shaft size to the existing tube and shaft in your conveyor frame
- Ensure the roller length fits within the frame spacing and allows for end caps or supports
- Use only for light weight products where the load per roller is low
- Avoid outdoor or wet environments where PVC may degrade over time
- Check that the shaft fits securely in the tube to prevent wobble or slippage

Manufacturing Process
Step 1
Extrusion of PVC tube to specified diameter and wall thickness
Step 2
Cutting of tubes to required length range
Step 3
Insertion of shaft into the tube with a press fit or interference fit
Step 4
Final inspection for straightness and shaft alignment
Step 5
Packing by model and length for shipment
Compared With Other Options
| Metal gravity rollers | PVC rollers are quieter and lighter, suitable for indoor use, but have lower load capacity than metal rollers |
|---|---|
| Powered roller conveyors | Gravity rollers require no power and are simpler to install, but cannot move product against gravity or over long distances |
| Standard plastic rollers with different shafts | This series offers consistent shaft sizes across models to match existing tube and shaft standards |
