Detect Cracks in Bearings Before They Cause Trouble

June 6, 2024by Marcbearing0

Cracked bearings pose a significant threat to machinery. If you don’t check, they can wreak havoc on your equipment, leading to expensive repairs, production delays, and even safety risks.

Detecting these issues requires specialized machinery and equipment tailored for various inspection methods. You must get them checked before they cause serious problems.

Here’s the lowdown on detecting bearing cracks:

Up-Close Inspection

At times, you may need to look at the bearing itself. This process, known as off-line testing, involves removing the bearing from the machine for a thorough inspection.

Here are some methods used for this detailed examination:

  • Closely examine the bearing for any visible cracks, wear, or other damage. While basic, it can be surprisingly effective for spotting major issues.
  • USE MAP (Magnetic Particle Inspection) techniques that involve using a magnet to reveal hidden cracks. The magnet disrupts the bearing’s magnetic field where cracks are present, attracting magnetic particles to these areas and making the cracks visible.
  • The process also includes ultrasonic testing, which uses high-frequency sound waves to detect hidden flaws. The sound waves pass through the bearing. Experts at MARC Bearings analyze how these waves bounce back to identify internal cracks or defects.
  • Dye Penetrant Inspection is another way. This method works like a magic marker for cracks. A special dye seeps into any cracks, and then a developer draws the dye out, making the cracks visible under ultraviolet light.

 

On-Line Monitoring

On-line monitoring means ensuring whether a bearing develops a sound or a crack while your machine is still running.

Here are some key methods:

  • Oil Analysis: Your machine’s lubricant acts like a blood test for bearings. By analyzing the oil for metal particles or debris, you can gain insights into the bearing’s health and detect potential cracks without needing a direct inspection.
  • Vibration Analysis: Note that good bearings vibrate in a specific way. With proper monitoring of vibrations, technicians can detect changes that might signal cracks or other problems.
  • Temperature Monitoring: Bearings with crack issues show unusual temperature variations. So, experts monitor the temperature to identify the cracking issue.
  • Acoustic Emission: in this method, professionals listen to tiny “creaks” that cracks make as they grow. they use special sensors on these high-frequency sounds without stopping the machine.

Crack Detecting Machine at MARC

MARC Bearings Pvt. Ltd – Rajkot, Gujarat – India uses a variety of machines to detect cracks in bearings.

For example,

The company uses a sensor in case of vibration analysis. The sensor is attached to the bearing to measure the vibrations of the bearing. Cracks in the bearing cause changes in the vibration pattern, which can be detected by the sensor.

In the case of acoustic emission testing, technicians at MARC attach a sensor to bearings to measure the sound emitted by the bearing. Cracks in the bearing cause changes in the sound pattern, which can be detected by the sensor.

MARC Bearings Pvt. Ltd – Rajkot, Gujarat – India professionals incorporate several methods and machines to detect cracks in bearings. The specific method that is used depends on the type of bearing and the application.
