| NB linear systems are heat-treated in order to harden the surface. Because of this, if the temperature of the system exceeds 100 °C, the hardness and rated load will be reduced (refer to Hardness Coefficient). If resin is used in any one of the components, the system cannot be used in a high-temperature environment. The recommended operating temperature ranges for each type of linear system are listed in the lower Table. |

| * If the system is made of stainless steel and has a seal, the temperature should be below 120 °C. |
| ** Contact NB if system is to be used at temperatures beyond the recommended temperature ranges. |
|
|
|
|
|
| Dust and perticle debris will adversely affect the motion characteristics of a linear system. They can also cause abnormally fast wear. In a normal operating environment, the use of seals may prevent adverse effects to the linear system. However, the linear system should be well protected by using bellows or a protective cover when it is used in an extremely hostile environment. |
