Serrated I bar is modified on the basis of I bar, possessing the advantages of both serrated flat bar and I bar. Serrated I bar is mainly used in the producing of Steel grating. Normally there are cold rolled and hot rolled I Type Serrated Flat Bar. As for the surface treatment, black or galvanized coating both are ok. We can also treat the surface of I type Serrated Flat Bar as customer's requirements.
Standard:ASTM,EN,GB,JIS
Packaging Details:According to the customer's requarement

1, scar sound (Brinell indentation) /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Scene: After the motor is installed; when noise is viewed; noise is found.
Characteristics: The sound of "咔啦啦......" was announced one after another.
Cause: When the shaft is pressed into the shaft collar or bearing chamber; Brinell indentation is generated inside the bearing.
Countermeasures: Select the bearing depicted by the indentation; to improve the installation qualification rate; "NSK" anti-indentation depiction.
2, scar sound (friction wear)
Set: The noise was found when the motor was transported to the air-conditioning plant for noise viewing.
Features: The sound of "咔啦......" was announced one after another.
Reason: Because of the fluctuation of the oscillation during transportation; the friction between the steel ball and the tumbling of the bearing causes the sound.
Countermeasures: Improve packaging and transportation methods; use anti-friction wear grease; to improve the pass rate.
3, foreign matter sound set: after the motor is installed; when the noise is checked, it is found to be noisy.
Characteristics: The sound of "啪哩啪哩..." is announced intermittently.
Reason: Foreign matter enters the inside of the bearing.
Countermeasures: Improve the cleanliness of the installation line, rotor and bearings.
4, adhere to the sound of the scene: after the motor is installed; when the noise is seen, there is noise.
Characteristics: The sound of "å½å“©å½å“©..." is announced consecutively or intermittently.
Reason: The noise caused by the conflict between the adherer and the steel ball.
Countermeasure: Select the stick grease that adheres to the sound of the instrument.
