In the professional transport sector, talking about profitability on the road means talking about the profit margin, not only is played in attracting new routes, but in the meticulous management of operating costs. Between fuel and wages, maintenance usually appears as an inevitable and often underestimated item. However, there is a metric that separates efficient fleets from those that simply survive: the Cost per Kilometre (CPK).
Often, the temptation to reduce immediate expenses leads to the acquisition of low-cost spare parts. But is it really a saving? At Industrias Onyarbi, after decades of manufacturing and marketing components for industrial vehicles, we have the clear answer: durability is the only real way to optimisation.
The Myth of Saving on the Purchase Price
When we talk about long-lasting spare parts, the first obstacle is usually the purchase price. A high-quality component may have a higher initial cost than a white-labelled part. However, the correct financial analysis should not stop at the supplier’s invoice, but at the product life cycle.
The actual calculation of the CPK of a replacement is defined by the following ratio:
CPK= Spare Part Price + Installation Cost + Inactivity Cost / Kilometre of useful life
If we buy a piece 20% cheaper but that lasts 40% less, the CPK skyrockets. If we add to that that each replacement involves hours of workshop and, most critically, a stopped vehicle, the initial savings become a flagrant operational loss.
The Three Pillars of CPK Optimisation, profitability on the road
To reduce the CPK effectively, that is, to improve the profitability on the road, Industrias Onyarbi focusses on three fundamental technical axes in the manufacture of its spare parts:
A. Materials Engineering and Wear Resistance
The difference between a bearing, a suspension or a standard braking component and a high-end one lies in its composition. In Onyarbi we use alloys and heat treatment processes that guarantee superior resistance to mechanical fatigue.
Fewer substitutions: By extending the maintenance intervals, the truck remains where it should be: on the road generating income.
Extreme reliability: We avoid unforeseen breakdowns that lead to costly emergency road repairs.
B. Accuracy of Adjustment and Energy Efficiency
A replacement that does not comply with the exact tolerances of the original equipment (OEM) generates unnecessary friction or vibrations that affect other components of the system. A poorly adjusted component not only breaks earlier, but can slightly increase fuel consumption. Our manufacturing processes ensure total compatibility, which reduces the mechanical stress of the whole vehicle and improves profitability on the road.
C. The Opportunity Cost: The Vehicle Stop
For a fleet manager, a truck in the workshop is an asset that loses value every hour and means losing profitability on the road. Onyarbi’s long-lasting replacements are designed to synchronise with preventive maintenance cycles. If a component lasts long enough not to require an extra entrance to the workshop between scheduled revisions, the logistical savings are massive.
Critical Cases: Suspension and Braking
If we analyse specific product families, the impact of quality replacement is even more evident:
Suspension Systems: Silentblocks and low-quality jet bars degrade the geometry of the axes quickly. This causes irregular tire wear. Here, the “cheap replacement” is doubly expensive: we have to change the part before and, in addition, we shorten the useful life of the tires.
Braking Systems: Thermal stability is key. Onyarbi components ensure a constant coefficient of friction. A low-quality replacement that suffers premature fading is not only a safety risk, but also accelerates the wear of the disc or drum, multiplying the cost of maintenance in the medium term.
Why choose Onyarbi Industries as a strategic partner
At Onyarbi we are not only marketers; we are manufacturers with technical DNA. We understand that every kilometre counts and profitability on the road is necessary for fleet managers. By integrating our spare parts into your fleet, you access:
Manufacturer’s Warranty: We control the entire process, from design to distribution.
Permanent Stock: Speed delivery is essential to minimise downtime.
Specialised Advice: We help fleet managers identify the critical points where investment in quality will generate a higher return (ROI).
Conclusion: From an Expense to an Investment
Optimising the cost per kilometre does not consist of spending less, but of spending better, here we are strictly talking about profitability on the road. The choice of long-lasting spare parts is a strategic decision that directly impacts the income statement of any transport company.
At Industrias Onyarbi, we remain committed to technical excellence, because we know that our quality is the engine of its profitability. On the road, cheap is expensive, and durable is the only thing that really saves.
