Rubber coating metal roller wheel W-30RB
The W-30RB is a rubber coated metal roller wheel with a 30 mm diameter and 9 mm width, designed for light to medium load applications where direct metal contact with the product must be avoided. It has a 6 mm shaft diameter and a 2.5 mm thick natural rubber coating, rated for 25 kg per piece. The wheel is made from carbon steel with a natural rubber outer layer and is used in material handling equipment and low to medium load conveying systems.
Product Overview
The W-30RB is a rubber coated metal roller wheel with a 30 mm diameter and 9 mm width, designed for light to medium load applications where direct metal contact with the product must be avoided. It has a 6 mm shaft diameter and a 2.5 mm thick natural rubber coating, rated for 25 kg per piece. The wheel is made from carbon steel with a natural rubber outer layer and is used in material handling equipment and low to medium load conveying systems.
Part of the Metal Roller Wheel range, used in Conveyor OEMs and System Integrators.
Key Benefits
- Rubber coating prevents product marking and protects delicate surfaces
- 30 mm diameter and 6 mm shaft size match standard tube and shaft dimensions
- 2.5 mm thick rubber layer provides cushioning and grip for smooth transfer
- Carbon steel core ensures structural strength under repeated load
- Simple mounting on standard shafts reduces setup time and tooling needs
Application Scenarios
- Conveyor lines transporting trays, plastic containers, or flat packaging without surface damage
- Assembly line transfer points where product finish must remain unmarked
- Warehouse handling equipment moving light components on smooth surfaces
- Floor-mounted trolleys or carts where wheels need to roll quietly and protect floor surfaces
- Light-duty conveying systems in food or electronics manufacturing where contamination must be avoided
Who It Is For
- Conveyor system integrators building low to medium load conveyors
- Material handling equipment builders requiring non-marking wheels
- Warehouse automation contractors installing light-duty transfer systems
- Industrial distributors stocking roller wheels by load and size
- Production line designers needing wheels that protect product finishes
Problems It Solves
- Product surfaces getting scratched or marked by direct metal contact during transport
- Inconsistent roller performance due to mismatched shaft or diameter sizes
- Need for multiple suppliers to source shaft, wheel, and coating separately
- Lack of consistent rubber thickness across similar roller wheel models
- Difficulty in replacing wheels without reconfiguring the entire shaft system
Technical Features
- Natural rubber coating with 2.5 mm thickness for cushioning and grip
- 30 mm diameter and 9 mm width for standard conveyor integration
- 6 mm shaft diameter compatible with common shafting and mounting systems
- Carbon steel core provides durability under repeated rolling load
- Rubber coating applied over a precision-machined metal roller for even wear
Materials
- Carbon steel core for strength and long-term performance under load
- Natural rubber coating for non-marking contact and improved traction
- Rubber layer applied over a machined metal surface for even thickness and durability
Quality Control
- Rubber thickness verified at multiple points around the circumference
- Shaft hole diameter checked against 6 mm specification
- Load capacity tested under static conditions to confirm 25 kg rating
- Visual inspection for coating defects, bubbles, or delamination
- Rolling test to confirm smooth rotation without wobble
Customization Options
- Available in other load ratings within the W Series for different capacity needs
- Shaft diameter can be adjusted if required, based on customer shaft specifications
- Rubber type can be changed upon request, though natural rubber is standard
- Diameter and width can be modified to match specific conveyor or system dimensions
Use Guide
- Ensure the shaft diameter matches the 6 mm specification before mounting
- Distribute load evenly across multiple wheels to stay within the 25 kg per unit rating
- Avoid using on products with uneven or soft bottoms that may compress the rubber
- Inspect rubber coating regularly for wear or delamination in high-use environments
- Use only on flat, smooth surfaces to maintain consistent rolling performance

Compared With Other Options
| Uncoated metal roller wheels | The W-30RB prevents product marking and reduces noise, while uncoated wheels risk surface damage and increased vibration |
|---|---|
| Plastic roller wheels | The W-30RB offers higher load capacity and better wear resistance than most plastic wheels, though it is heavier |
| Thicker rubber coated wheels | The 2.5 mm rubber layer is suitable for light to medium loads; thicker coatings are available in other models for higher cushioning needs |
