Pu coating metal track roller W-40PU
The W-40PU is a metal track roller with a polyurethane (PU) coating, designed for light to medium load conveying applications where direct contact between the product and metal must be avoided. It has a 40 mm diameter, 9 mm width, and a 6 mm shaft hole, with a load capacity of 30 kg per piece. The unit is made from carbon steel with a 2 mm thick PU coating, providing a smooth, quiet roll and protection against surface damage.
Product Overview
The W-40PU is a metal track roller with a polyurethane (PU) coating, designed for light to medium load conveying applications where direct contact between the product and metal must be avoided. It has a 40 mm diameter, 9 mm width, and a 6 mm shaft hole, with a load capacity of 30 kg per piece. The unit is made from carbon steel with a 2 mm thick PU coating, providing a smooth, quiet roll and protection against surface damage.
Part of the Metal Roller Wheel range, used in Conveyor OEMs and System Integrators.
Key Benefits
- PU coating prevents product marking and surface damage on trays and flat items
- 30 kg load capacity per unit suitable for light to medium load conveying
- Carbon steel core provides strength and durability under repeated use
- 6 mm shaft hole allows for easy mounting on standard M6 shafts
- Compact 40 mm diameter and 9 mm width fit into tight conveyor spaces
Application Scenarios
- Conveyor lines in packaging and assembly stations handling flat trays or small components
- Warehouse material handling systems where product surface finish must be preserved
- Transfer points between conveyors where smooth, quiet movement is required
- Light-duty sorting and routing systems in logistics and distribution centers
- Floor-mounted wheels for moving equipment or tool trolleys in industrial settings
Who It Is For
- Conveyor system integrators building low to medium load conveyors
- Material handling equipment builders requiring non-marking rollers
- Warehouse automation contractors installing protective conveying solutions
- Industrial distributors stocking metal rollers with PU coating by load rating
- Production line builders integrating rollers into assembly or inspection stations
Problems It Solves
- Product surface damage caused by direct contact with bare metal rollers
- Noise and vibration from metal-on-metal contact in light load conveying
- Difficulty in moving flat, smooth items on standard rollers due to poor grip
- Lack of consistent non-marking rollers in a single supplier range
- Inconsistent roller performance when switching between different materials
Technical Features
- Polyurethane coating with 2 mm thickness for wear resistance and quiet operation
- Carbon steel body provides structural strength and load support
- 6 mm shaft hole compatible with standard M6 shafts for easy installation
- 40 mm diameter and 9 mm width designed for compact conveyor layouts
- PU coating maintains grip on flat, smooth surfaces without slipping
Materials
- Carbon steel core for structural strength and long-term use
- Polyurethane (PU) coating for non-marking, quiet, and wear-resistant surface
- 2 mm thick PU layer to resist abrasion and maintain roll smoothness
Quality Control
- Coating thickness verified at 2 mm across the roller surface
- Shaft hole diameter checked to ensure 6 mm tolerance
- Load capacity tested to confirm 30 kg per piece rating
- Surface finish inspected for uniformity and absence of defects
- Rolling motion checked by hand for smooth, consistent rotation
Customization Options
- Available in other sizes within the W Series including W-30RB and W-45RS
- Shaft diameter can be adapted to match existing M6 shafts
- Coating thickness may vary in other models, but not specified for W-40PU
- Material options limited to carbon steel with PU coating as per current model
Use Guide
- Ensure the product being conveyed has a flat, smooth bottom surface
- Do not use on soft or uneven surfaces such as cloth-wrapped items
- Mount on M6 shafts to ensure proper alignment and load transfer
- Check that the roller is fully seated and rotates freely after installation
- Use only in applications where the load per roller does not exceed 30 kg

Compared With Other Options
| Plain carbon steel rollers | The W-40PU's PU coating prevents product marking and reduces noise, while steel rollers risk surface damage |
|---|---|
| Rubber-coated rollers | PU offers better wear resistance and load handling than standard rubber, especially under medium load |
| Other W Series rollers | W-40PU has higher load capacity than W-45RS and larger diameter than W-30RB, making it suitable for medium-duty applications |
