All mechanical systems experience wear over time, and the need for replacement parts is not a matter of if, but when. Businesses are often faced with a choice between original equipment manufacturer (OEM) or generic alternatives. While both options may appear similar at first glance, the decision can have significant impacts on equipment performance, reliability, and long-term operating costs.
OEM components are not designed in isolation; they are engineered as part of a complete system. Each part is designed to interact with surrounding components, ensuring consistent performance across the entire machine. In many cases, these parts have undergone extensive testing to ensure proper fit, performance, and durability under real operating conditions.
Using OEM parts means that a business will have access to manufacturer warranties, technical support, and service guidance. This support helps ensure that maintenance is performed correctly and that the equipment continues operating as intended. For businesses that rely on consistent production performance, OEM parts help maintain the original design integrity of the machine while reducing the risk of unexpected downtime.
When a new machine is purchased, the manufacturer can make suggestions for when parts should be replaced. These recommendations are based on engineering design, historical performance data, and real-world usage. Each of our new machines is delivered with critical spare parts and specifications for the machine.
Manufacturers can also provide training to the customers’ employees on how to maintain their parts. As improvements or upgrades are developed over time, customers using OEM components can also benefit from these enhancements. This helps reduce long-term operating costs while supporting consistent machine performance and reliability.
Generic parts are manufactured by third-party organizations. In some situations, businesses may turn to generic parts when an immediate replacement is needed. For example, if a machine failure causes unexpected downtime, a generic component may appear to be the fastest option compared to waiting for a manufacturer-supplied part.
Even high-quality generic parts introduce variability because they are not engineered with full visibility into the system they are being installed into. That variability may not be immediately visible, but over time it can increase maintenance frequency, reduce efficiency, and introduce unplanned costs. For example, in a filler, even a minor change in a valve seal can affect the fill profile.
Material mismatches can lead to premature wear, sanitation risks, or even complete component failure. If, for example, your machine is made from AL6XN steel, which has high nickel content, but a generic replacement part is made of 316L steel, it may not withstand the cleaning processes that work well with your AL6XN machine. Similarly, in systems such as the EL-G filler, actuators rely on precise interaction between pistons and seals. If a replacement component is manufactured from an incompatible material, the piston may seize, preventing the valves from opening or closing properly.
Using generic parts can also create challenges in maintaining accurate equipment records. Over time, this can result in a ‘Frankenstein’ machine—built from mismatched components with no clear record of origin, performance expectations, or service history. It is important for the longevity of the machine to document what parts are being used and to talk with the manufacturer about any reasons why non-OEM parts are used so they can provide efficient support.
To address documentation challenges, U.S. Bottlers has developed a system to track where components originate. We also partner with prequalified third-party suppliers so customers can order OEM approved components through U.S. Bottlers. This helps ensure that machine records remain accurate while giving customers flexibility when sourcing parts. Clear communication between the customer and the manufacturer is essential to maintaining machine integrity over many years of operation.
All U.S. Bottlers machines come with a minimum 1-year warranty and include a 24-hour technical support hotline. Our service technicians are trained to troubleshoot problems. However, if a machine has undocumented generic parts, it can be difficult to determine what parts are installed or how they may affect machine performance. In production environments, even small delays in troubleshooting can translate directly to lost output and revenue. When machines are maintained with OEM parts, the technicians can immediately access specifications, service history, and replacement guidance. This allows issues to be resolved more quickly and helps restore production with minimal disruption.
While generic parts may offer short-term convenience, OEM components provide the consistency, support, and system-level reliability required to keep equipment running as designed over the long term.
