One of the critical components of machine components in cement plants is the slewing bearing, This bearing enables the stacker to rotate smoothly around its central axis, allowing for precise placement and alignment of materials as they are stacked or reclaimed. As the time passes, these bearings can wear out, demanding the replacement to maintain operational efficiency. Tarek Nasser Al Akeel Co. (TNA) specializes in the replacement of stacker slewing bearings to increase optimal performance throughout your operations.
Slewing bearings are designed to support the weight of the upper structure of stacker reclaimers while allowing for rotational movement. They are subjected to significant loads and environmental conditions, which can lead to wear, deformation, and failure over a while. Regular inspection and timely replacement of slewing bearings are essential to avoid unexpected breakdowns and maintain productivity.
1. Minimized Downtime: TNA plans for an efficient replacement procedure that minimizes shutdown time, allowing operations to resume quickly.
2. Expertise and Experience: With years of experience in the field, TNA's technicians are skilled in handling the complexities of slewing bearing replacement.
3. Quality Assurance: TNA uses high-quality bearings that surpass industry standards, ensuring reliability and longevity.
4. Safety Compliance: TNA follows strict industrial safety protocols during the replacement process.
The replacement of slewing bearings involves a systematic approach:
1. Initial Assessment: A thorough inspection of the slewing bearing and surrounding components is undertaken to determine the existing condition and identify any additional issues.
2. Preparation: The stacker reclaimer is taken offline for maintenance. This may involve securing the upper structure.
3. Lifting the Upper Structure: Sufficient scaffolding is built. The upper structure is lifted using jacks and supports. Any custom required tools are required, they are built in advance and used during the operations.
4. Removal of the Old Bearing: The worn slewing bearing is carefully removed from its housing.
5. Surface Preparation: The bearing housing is cleaned and inspected for any wear or damage. This is important before installing the new one.
6. Installation of the New Bearing: The new slewing bearing is installed, ensuring proper alignment. Essential jigs and fixtures are used. It is crucial to achieve the correct flatness, typically within 0.2 mm, to ensure optimal performance.
7. Final Inspection and Testing: After installation, the system is thoroughly tested to ensure everything works smoothly.
