How the right belts and pulleys help prevent costly downtime

Keeping production moving is essential. Every machine, component and process has a role to play in meeting targets, fulfilling orders and keeping customers happy.

Even a relatively minor mechanical failure can bring an entire production line to a halt. A worn drive belt, damaged pulley or poorly maintained transmission system can quickly become a much bigger business problem.

The financial consequences of industrial downtime extend far beyond the immediate cost of repairs. Lost production, delayed deliveries, contractual penalties and disruption to the wider supply chain can all follow from a single equipment failure.

For manufacturers, particularly those operating to tight production schedules, reliability is fundamental to profitability.

The true cost of industrial downtime

The financial impact of unplanned downtime is considerable, and the figures are particularly concerning for South African industry.

According to ABB’s Value of Reliability survey, published in October 2023, 72% of South African industrial businesses surveyed experienced unplanned equipment outages at least once a month.

The same research estimated that unplanned downtime costs a typical South African industrial business approximately R724,000 per hour.

The international picture is equally striking.

Siemens’ True Cost of Downtime 2024 report estimated that unplanned downtime costs the world’s 500 largest companies approximately US$1.4 trillion annually, equivalent to 11% of their combined revenue.

The study also found that a large manufacturing plant loses an average of 27 hours per month to unplanned downtime, illustrating how even relatively short interruptions can accumulate into substantial losses.

Lost production is only the beginning

The most immediate consequence of a machinery breakdown is reduced output.

When equipment stops working, production capacity is lost. Employees may be unable to continue their tasks and scheduled work begins to fall behind.

Even after repairs are completed, normal operations may not resume immediately. Machinery may need to be restarted, tested and recalibrated before full production can continue.

Businesses can also face additional costs from emergency repairs, replacement components, overtime and increased pressure on maintenance teams.

For manufacturers operating close to full capacity, recovering that lost production can be especially difficult. There may simply be insufficient time or available machinery to make up the shortfall.

The consequences become more serious when downtime begins affecting commitments to customers.

When production delays become contractual problems

Manufacturers frequently operate under agreements requiring them to deliver specific quantities of products within agreed timescales.

These commitments can be particularly demanding when supplying larger manufacturers, major retailers or businesses operating on tightly coordinated production schedules.

An unexpected equipment failure can put those obligations at risk.

If a manufacturer cannot deliver an order on time, the consequences may include contractual penalties, additional transport costs or the need to negotiate revised delivery arrangements.

Repeated delays can also damage commercial relationships and make customers less confident about placing future orders.

Siemens specifically highlights this problem in its 2024 downtime research, noting that smaller manufacturers supplying larger organisations may be assessed on their ability to deliver orders.

A poor delivery record can threaten a manufacturer’s position as an approved supplier, potentially affecting future contracts and revenue.

The cost of downtime can continue long after the machinery is running again.

The knock-on effect across supply chains

Modern manufacturing relies on interconnected supply chains. Components, materials and finished goods must arrive at the right time for production to continue efficiently.

A breakdown at one factory can therefore create problems for several other businesses.

Consider a manufacturer supplying components to an automotive assembly plant. If a critical belt-driven machine fails, production of those components may stop. The manufacturer misses its delivery window, leaving the assembly plant without the parts required for its own production.

That disruption can then affect the assembly plant’s customers and delivery commitments.

Similar problems can occur in food processing, packaging, mining and other industries where production activities depend on a reliable flow of materials and components.

Siemens’ research identifies these interconnected supply chains as a significant factor in the increasing financial cost of downtime, including the potential for contractual penalties to spread between suppliers and their customers.

Reliable machinery is therefore important to the wider network of businesses that depend on a manufacturer’s output.

Why belts and pulleys matter to production reliability

Industrial belts and pulleys play an important role in machinery across manufacturing and processing environments.

They transfer power between rotating shafts, drive mechanical equipment and help keep production systems operating at the required speeds.

Different applications require different types of transmission components. V-belts, timing belts, Poly V-belts and variable speed belts are designed for particular operating conditions and performance requirements.

Although these components may represent a relatively small proportion of a machine’s overall value, their failure can interrupt the operation of much more expensive equipment.

Choosing appropriate components, installing them correctly and maintaining them regularly can reduce the likelihood of avoidable failures.

The importance of quality and preventative maintenance

When purchasing replacement belts or pulleys, it can be tempting to focus primarily on the initial price.

However, the cheapest component may not offer the best overall value, particularly in demanding industrial environments.

A belt that needs replacing more frequently can create additional maintenance costs and interruptions. If it fails unexpectedly, the resulting loss of production could be considerably more expensive than the component itself.

That does not mean every application requires the most expensive belt available.

The important consideration is selecting a product suited to the machinery’s operating conditions, including load requirements, running speed, temperature and expected usage.

Preventative maintenance is equally important. Regular inspections can help identify developing problems before they cause a breakdown.

A practical maintenance approach should include:

• Checking belts for cracking, unusual wear, fraying and other signs of deterioration.
• Confirming that belt tension and pulley alignment meet the manufacturer’s specifications.
• Inspecting pulleys for wear or damage that could affect belt performance.
• Identifying critical replacement components and maintaining suitable spare stock.
• Planning belt replacements and maintenance activities around scheduled production stoppages.

These checks should be undertaken by appropriately trained personnel, following the necessary machinery isolation and safety procedures.

The objective is to identify potential failures early, reducing the risk of emergency shutdowns and allowing maintenance teams to plan their work.

Keeping South African industry moving

For South African manufacturers, reliable access to suitable industrial transmission components is an important part of maintaining production continuity.

Having the correct replacement available when it is needed can reduce repair delays. Equally, choosing an appropriate component in the first place can help extend service life and reduce avoidable maintenance.
