Chain and roller combination
The combination of chain body (4 types) and roller (7 types) (marked with ○ below) allows you to select the best fit for your application. The same combinations are also available for Double Plus Free Flow Chains with snap covers.

*1 Urethane lining is only available for RF2030VRP size.
*2 The parts become slightly magnetic due to plastic deformation during processing and assembly. Please contact us if you require a completely non-magnetic product.
Roller application classification
| Roller specifications | image | Roller type | Usage classification | Lubrication | atmosphere | |
|---|---|---|---|---|---|---|
| Large diameter roller () indicates color |
Small diameter roller () indicates color |

| VRPA General-purpose type |
 |
usually (tea) |
usually (gray) |
Better than general-purpose plastic side chains -10dB low noise |
Use without lubrication. If you use the lambda specification, there is no need to lubricate. |
The chain body is HCP or SS Series Even in this case, use Plastic Roller. Use in places where water may splash. It cannot be used. |
| VRPB High friction type |
 |
usually (tea) |
high friction (cream) |
Quick start-up and low noise | ||
| VRPC Conductive Type |
 |
conductive (black) |
usually (gray) |
Volume specific surface resistivity 10 6 Ω·cm | ||
| VRPD Conductive, high friction type |
