For separate installation, the inner ring and outer ring can be conveniently installed on the shaft or seat respectively Fag Roller Bearing At this time, it should be noted that when inserting the shaft with the inner ring into the bearing housing with the outer ring, try to keep it concentric to prevent scratching the rolling element and raceway.
When the size of roller bearing is large, due to the large installation force required or the large fit interference of fag bearing under heavy load, it is difficult to adopt cold installation, it is necessary to heat the inner ring or seat in advance before installation. Fag Roller Bearing During hot installation, the heating temperature shall be strictly controlled.
When heating fag bearing, the heating temperature shall not exceed 1200C, generally 80 ~ 1000C. The with dust cover or sealing ring shall not be heated, otherwise it will cause lubricant loss. The heating method can be electric induction beauty, oil bath heating, etc. Fag Roller Bearing Whether the bearing is installed or not will affect the accuracy, service life and performance of roller bearing.
1、 Clean the bearings and related parts. The grease lubricated bearings and both sides are provided with oil seals or dust covers. Fag Roller Bearing The sealing ring bearings do not need to be cleaned before installation.
2、 Check the dimension and finish machining of Fag Roller Bearing relevant parts of roller bearing
3、 Installation method the installation of roller bearing shall be determined according to the bearing structure, size and matching properties of bearing components. The pressure shall be directly added to the end face of the tightly matched ferrule, and the pressure shall not be transmitted through the rolling element, Fag Roller Bearing The following methods are generally adopted for bearing installation:
(1) keep the bearing and its surroundings clean. Even small dust invisible to the eyes will have a bad impact on fag bearing. Therefore, keep the surroundings clean so that the dust will not invade the bearing. (2) Fag Roller Bearing Use it carefully. Strong impact on the roller bearing during use will produce scars and indentation, which will become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention.
(3) use appropriate operating tools. Avoid replacing existing tools, and use appropriate tools. (4)Fag Roller Bearing Pay attention to the corrosion of the roller bearing. When operating the roller bearing, the sweat on your hands will become the cause of rust. Pay attention to operate with clean hands and wear gloves as much as possible. After the installation of NTN bearing, in order to check whether the installation is correct, operation inspection shall be carried out.
The inspection items include poor operation caused by foreign matters, scars and indentation, unstable torque caused by poor installation and poor processing of mounting base, Fag Roller Bearing excessive torque caused by too small clearance, installation error and sealing friction, etc. If there is no abnormality, power operation can be started.
Power operation, starting from no-load low speed, slowly increase to the rated operation under the specified conditions.Fag Roller Bearing During the test run, check whether there is abnormal sound, temperature change of self-aligning ball bearing, lubricant leakage or discoloration, etc. If any abnormality is found, stop the operation immediately, check the machinery, and remove the bearing for inspection if necessary.
