對于大多數循環滾珠和滾柱直線導軌，允許的工作溫度范圍為-10°80°C，某些配置的額定溫度可在短時間內達到100°C。但并非所有應用都在此溫度范圍內，直線軸承組件中的每個部件（外殼、導軌、滾珠、密封件等）都有不同的高和低工作溫度。但是，如果您選擇了正確的金屬部件、塑料部件、潤滑和可選配件，您也可以配置出一個循環直線導軌，可以承受標準-10°80°C范圍之外的高溫（或低溫）應用。

For most circulating ball and roller linear guides, the allowable operating temperature range is -10 ° to 80 ° C, and some configurations have a rated temperature that can reach 100 ° C in a short period of time. But not all applications are within this temperature range, and each component in the linear bearing assembly (shell, guide rail, ball, seal, etc.) has different high and low operating temperatures. However, if you choose the correct metal components, plastic components, lubrication, and optional accessories, you can also configure a circular linear guide that can withstand high (or low) temperature applications outside the standard range of -10 ° to 80 ° C.

金屬部件

Metal parts

導軌絲杠廠家認為，其循環直線導軌的金屬部件包括軸承座、循環滾珠或滾子、導軌、刮板以及各種緊固和安裝螺釘。這些部件的構成可以包含三種或更多不同類型的鋼、不銹鋼，在某些情況下還包括鋁。因此，重要的是要了解每個組件由哪種金屬制成，以及它可以承受的溫度范圍。

The manufacturer of guide screw believes that the metal components of its circulating linear guide include bearing seats, circulating balls or rollers, guide rails, scrapers, and various fastening and installation screws. These components can consist of three or more different types of steel, stainless steel, and in some cases, aluminum. Therefore, it is important to understand which metal each component is made of and the temperature range it can withstand.

在許多情況下，制造商建議在應用超出正常工作溫度范圍時盡可能使用不銹鋼，尤其是在溫度非常高（高于150°C）或非常低（低于0°C）時。此建議的原因之一是溫度波動的可能性，這可能會導致冷凝并導致腐蝕。

In many cases, manufacturers recommend using stainless steel as much as possible when the application exceeds the normal operating temperature range, especially when the temperature is very high (above 150 ° C) or very low (below 0 ° C). One of the reasons for this suggestion is the possibility of temperature fluctuations, which may lead to condensation and corrosion.

直線軸承和導軌由各種不同的材料制成——每種材料都有特定的可接受工作溫度范圍。

Linear bearings and guide rails are made of various materials - each with a specific acceptable operating temperature range.

塑料部件

Plastic components

塑料部件，例如密封件和循環部件，通常是循環直線軸承溫度適用性的限制因素。但是，直線導軌制造商提供由特殊材料制成的密封件，例如FPM或FKM（氟化橡膠，通常稱為Viton，來自杜邦），具有擴展的工作溫度范圍。

Plastic components, such as seals and circulating components, are usually limiting factors for the temperature applicability of circulating linear bearings. However, linear guide rail manufacturers provide seals made of special materials, such as FPM or FKM (fluorinated rubber, commonly known as Viton, from DuPont), with an extended operating temperature range.

如果環境不存在液體或固體污染，另一種選擇是使用僅帶有金屬密封件的直線導軌。盡管不建議將完全放棄的密封件用于異形直線導軌（因為它們有助于保持軸承內部的潤滑），但圓軸直線導軌和凸輪滾子滑軌可以在沒有密封件的情況下運行，使其成為不要求應用的另一種選擇用于異形直線導軌的負載能力或剛度。由于這些設計不需要塑料再循環組件，因此它們提供全金屬版本，可以承受大多數塑料范圍之外的溫度。

If there is no liquid or solid pollution in the environment, another option is to use linear guides with only metal seals. Although it is not recommended to use completely abandoned seals for irregular linear guides (as they help maintain lubrication inside the bearings), circular axis linear guides and cam roller guides can operate without seals, making them an alternative choice for load capacity or stiffness of irregular linear guides that do not require application. Due to the fact that these designs do not require plastic recycling components, they provide an all metal version that can withstand temperatures outside the majority of plastic ranges.

密封件有助于保持軸承內部的潤滑，但在高或低溫度的環境中可能需要特殊的密封材料。

Seals help maintain lubrication inside bearings, but special sealing materials may be required in high or low temperature environments.

潤滑

lubrication

溫度也會影響循環直線導軌的潤滑性能。具體來說，潤滑劑的溫度會影響其粘度（流動阻力），超過其額定溫度的油脂潤滑會分離成其成分（基礎油、增稠劑和添加劑），從而降低其有效性。

Temperature can also affect the lubrication performance of the circulating linear guide. Specifically, the temperature of a lubricant can affect its viscosity (flow resistance), and grease lubrication that exceeds its rated temperature will separate into its components (base oil, thickener, and additive), thereby reducing its effectiveness.

一般來說，較低粘度的潤滑劑用于低溫應用，而較高粘度的潤滑劑適合高溫應用。請記住，除了要使用的潤滑類型外，的潤滑間隔還受軸承工作溫度的影響。

Generally speaking, lubricants with lower viscosity are recommended for low-temperature applications, while lubricants with higher viscosity are suitable for high-temperature applications. Please remember that in addition to the type of lubrication to be used, the recommended lubrication interval is also influenced by the bearing operating temperature.

可選組件和附件

Optional components and accessories

溫度限制也適用于可選組件，例如附加密封件、外部潤滑單元和蓋條或波紋管。例如，循環直線導軌的額定使用溫度通常高達80°C，但外部潤滑單元的高額定溫度通常為50°60°C。敏感組件，如測量系統（集成線性編碼器）和零件還應檢查與再循環系統不可分割的部件，例如球鏈或球分離器，以確保它們能夠承受過高或過低的工作溫度。

Temperature limitations also apply to optional components such as additional seals, external lubrication units, and cover strips or bellows. For example, the rated operating temperature of a circulating linear guide rail is usually as high as 80 ° C, but the high rated temperature of an external lubrication unit is usually 50 ° to 60 ° C. Sensitive components, such as measurement systems (integrated linear encoders) and parts, should also be inspected for components that are inseparable from the recirculation system, such as ball chains or ball separators, to ensure that they can withstand high or low operating temperatures.
