An Inspection Guide to Cross Head Bearings

A cross head bearing is a cross head part. The mechanism of cross head bearing is highly significant in reciprocating engines, compressors, industrial machines, production lines of manufacturing companies, vehicles, etc.

The productivity of engines and industrial machines are based on the good health and medical effectiveness of cross head bearings. Therefore, it is highly essential to inspect and evaluate the performance of cross head bearings time by time.

The inspection process will help to take corrective measures to ensure consistency in the adequate progress of cross head bearing. For conducting the inspection, first, we need to gather some useful information.

Information Needed for Conducting Cross Head Bearing Inspection

• Identify the cylinder class cross head bearing needs to be inspected.
• Acquire records of previous inspections of cross head bearings and check out the progress, check out the positive ticks and negative ticks. Here one need to ensure further that are positive points are working in progress with consistency? And are negative points which were highlighted last time had been recovered?
• Acquire log readings and latest cards of the indicator from the engine to evaluate excess pressures of the cylinder and lube oil examination. The lube oil examination is also helpful to assess impurities and condition of lube oil.

Procedure of Conducting Cross Head Bearing Inspection

In the light of information gathered as mentioned above. Now review the purpose of inspection to recall the motive in mind during the inspection. The purpose can be identifying the previous failures in performance, checking the fitness of cross head bearing to ensure effective performance, etc.

The following regions needs to be inspected assuming if cross head bearing needs replacement:-

• Evaluate the environment and conditions of a surface over cross head bearing are placed. Make sure there should be no existence of corrosion around cross head bearing.
• There must be the firm attachment of metal (white) to the line of bearing.
• Check out are there adequate and clear oil reservoirs present on the lower half side of cross head bearing?
• Is there any corrosion available on the bolts?
• Ensure that are all devices of fastening renewed?
• Conduct visual inspection of cross head bearings if possible. Visual inspection of cross head bearing shows off bolts health progress that binds cross head bearings with the object. It also helps to reveal cracks placed in frames during the welding process.
• The pins can be tested through Non-Destructive Testing (NDT) methods to ensure any existence of cracks damaging the object.
• The pins analysis is also useful to check out overheating and scoring impact. Overheating and scoring can damage the bearing.
• Visual evaluation of input pipe oil is also critical to check. It helps in pinpointing the defects. Here, you need to ensure free operation/movement of the object to avoid defects.

Conclusion

The inspection should be conducted by any technical staff from the organization. Generally engineers conduct inspection surveys of cross head bearings. Cross Head Bearings Manufacturers also conduct inspection before launching the cross head bearing into the market.

However, some companies used to conduct surveys during failure of equipment, but inspection should be done time by time to keep the check on the progress and avoid any failure or accidental situation.
