Rotary Shaft Repairs

Metalock Engineering offers specialised on-site rotary shaft repair services that can be a cost-effective alternative to shaft replacement. We focus on minimising downtime and enhancing operational efficiency, supporting businesses in maintaining seamless production processes. Read on to learn how Metalock swift response and expertise can restore your rotary shafts to peak condition, preventing costly disruptions and maintaining optimal performance.

With every failed bearing there is a failed shaft journal. In certain circumstances, repair can be a viable option when compared with the cost of replacement, so consider our on-site shaft repair services.

Our Rotary Shaft Repair Service

Whether it is naval or paper, power plant, or steel, our rotary shaft repairs address the needs of various industries. At Metalock Engineering, we utilise advanced techniques to deliver precision restoration of worn or damaged machinery shafts. This supports operational efficiency, a point further enhanced by our swift response and specialised expertise in this field.

Forget about downtime harming your profit margins. We can recover shaft bearing journals and return your machinery back to production using our orbital techniques.

Preventative Maintenance for the Future

Improved efficiency: Rotating machinery breakdowns can be a result of misaligned shafts, so it’s important to not only recover the bearing journal diameter but also to check the alignment before putting the machinery back into service. Correct alignment can mean the machinery operates with more efficiency while running smoothly. It also reduces energy consumption while increasing output simultaneously, which results in an improvement of the equipment’s overall performance.
Better precision and quality output: Machinery availability is important across all industries. Well-maintained equipment supports greater accuracy and consistency in output. It is an essential ingredient for maintaining quality standards and meeting specific industry requirements.
Extend machinery lifespan: Regular maintenance of rotary equipment significantly extends the life of the machinery. It prevents premature wear and tear from occurring, which reduces the likelihood of costly replacements and repairs. It can even maintain the equipment’s value over time.
Reduced downtime and maintenance costs: By being proactive with machinery upkeep, it minimises the chances of unexpected breakdowns and failures. This reduces downtime and associated costs, resulting in more continuous and reliable operation and enhanced productivity.
Improved safety: Well-maintained shafts and bearings reduce the risk of accidents and mechanical failures, creating a safer operating environment. This is essential in industries where equipment failure can lead to serious safety hazards.

With decades of experience, Metalock Engineering excels in rotary shaft repair across a multitude of industries. This includes steel, naval, paper, and marine industries. Our expertise lies in restoring damaged shafts to a serviceable condition, where we tackle wear, misalignment, and damage with precision. This is supported by advanced techniques we employ, alongside swift and reliable service to minimise downtime.

Our commitment to quality helps your on-site machinery to operate efficiently and reliably, enhancing overall productivity in the process.

Common Causes for Rotary Shaft Damage or Degradation

Misalignment and imbalance: When rotary shafts are misaligned, it causes uneven force distribution and, ultimately, excessive vibration. This imbalance accelerates wear that can result in bearings and seal failures. Alongside significantly shortening the shaft’s lifespan, it may cause potential damage to connected machinery components.

Wear and tear from irregular use: This causes reduced performance over time, affecting the efficiency of the entire machine. Harsh operating conditions or not following a diligent maintenance schedule can exacerbate irregular wear.

Corrosion and environmental factors: Exposure to moisture or extreme temperatures – can cause rotary shafts to degrade. The weakening of the shaft’s structure makes it susceptible to cracks and breaks.

Mechanical stress and overloading: Problems can arise when rotary shafts are subjected to loads beyond their design capacity or unexpected mechanical stress. These potential issues include deformations, fractures, or, in the most extreme cases, complete failure.

Inadequate lubrication and maintenance: Poor lubrication causes increased friction and heat buildup, accelerating the wear of rotary shafts. A lack of regular maintenance can further hasten severe damage to both the shaft and the equipment it operates in.
