不銹鋼螺母經過加工或熱處理徐州SKF軸承硬化。因此，選擇螺母進行熱處理，以促*進固體螺母的使用。這里有兩個要點，看看哪些螺母適合使用。

Stainless steel nuts are hardened by processing or heat treatment of Xuzhou SKF bearing. Therefore, nuts are selected for heat treatment to promote the use of solid nuts. Here are two main points to see which nuts are suitable for use.

1。熱處理不能加強

1. Heat treatment cannot be strengthened

鐵素體和奧氏體不銹鋼不能通過熱處理進行強化。為了提高耐蝕性和塑性，消*除冷加工硬化，應進行固溶處理。對于形狀復雜、固溶處理不當的緊固件，可進行應力消*除退火，對于含鈦或鈮的不銹鋼可進行穩定退火。因此，徐州SKF軸承可以獲得穩定的耐腐蝕性。

Ferrite and austenitic stainless steel can not be strengthened by heat treatment. In order to improve corrosion resistance and plasticity, solid solution treatment should be carried out to eliminate cold work hardening. For the fasteners with complex shape and improper solution treatment, stress relief and de-annealing can be carried out, and for stainless steel containing titanium or niobium, stable annealing can be carried out. Therefore, Xuzhou SKF bearing can obtain stable corrosion resistance.

2。強化熱處理

2. Enhanced heat treatment

馬氏體不銹鋼要求高*強度和彈性極限。耐腐蝕性低的緊固件應在中溫下淬火和回火。具有良好機械性能和耐腐蝕性的緊固件應在高溫下淬火和回火。奧氏體-鐵素體（雙相）不銹鋼需要退火以消*除加工應力，降低硬度，提高塑性。只有改進徐州SKF軸承原有結構的緊固件，才能通過高溫正火和回火進行預熱。

Martensitic stainless steel requires high strength and elastic limit. Fasteners with low corrosion resistance should be quenched and tempered at medium temperature. Fasteners with good mechanical properties and corrosion resistance should be quenched and tempered at high temperatures. Austenitic-ferritic (duplex) stainless steel needs annealing to eliminate working stress, reduce hardness and improve plasticity. only by improving the fastener of the original structure of Xuzhou SKF bearing, can it be preheated by high temperature normalizing and tempering.

特點1：內外圈可自*由拆卸，為軸承的安裝拆卸提供了極大的方便。

Feature 1: The inner and outer rings can be disassembled by themselves, which provides great convenience for the installation and disassembly of bearings.

特點二：圓柱滾子軸承對軸承座的加工要求較高。如果軸承座不能滿足圓柱滾子軸承的安裝要求，就會產生軸承應力不均勻的問題。安裝后，必*須仔細檢查軸承的外圈線是否有任何偏差。如果發現外環的軸線有偏差，應及時調整徐州SKF軸承。

Characteristic 2: Cylindrical roller bearings have higher requirements for the processing of bearing seat. If the bearing seat can not meet the installation requirements of cylindrical roller bearings, the problem of uneven bearing stress will arise. After installation, it is necessary to carefully check whether there is any deviation in the outer ring line of the bearing. If the axis of the outer ring is found to be deviated, the Xuzhou SKF bearing should be adjusted in time.

特點3：軸向移動可防止安裝偏差。圓柱滾子軸承屬于NU型軸向運動，在安裝過程中不受軸偏移的影響，也可作為自*由端使用。

Feature 3: Axial movement can prevent installation deviation. Cylindrical roller bearings belong to NU type axial motion, which is not affected by shaft offset in the installation process, and can also be used as self* free end.

特點4：低摩擦，能滿足高速運轉。圓柱滾子軸承在旋轉過程中摩擦系數小，非常適合高速運行。

Characteristic 4: Low friction, can meet high-speed operation. Cylindrical roller bearings have small friction coefficient in the process of rotation and are very suitable for high-speed operation.

特性5：屬于熱穩定產品，適用于電主軸。具有自動溫度識別、自感溫差變化和開*放式溫度補償功能，從而延長設備的使用壽命，減少軸承內外圈熱損傷引起的徐州SKF軸承摩擦。

Characteristic 5: It belongs to thermal stability product and is suitable for motorized spindle. It has the functions of automatic temperature identification, self-inductance temperature variation and open temperature compensation, so as to prolong the service life of the equipment and reduce the friction of Xuzhou SKF bearing caused by thermal damage of the inner and outer rings of the bearing.
