Roller chain components play a crucial role in keeping industries running smoothly. Whether it's transmitting power or moving conveyor belts in distribution centers, these parts are put under immense strain daily. Over time, they inevitably wear out due to constant use. Fortunately, replacing these parts is relatively straightforward, although finding every single component in one place isn’t always feasible.

At The Big Bearing Store, we’re here to assist you in sourcing the roller chain components you require. From B-hub sprockets and conveyor roller chains to offset or connecting links, we’ve got everything you need. All our products comply with or exceed ANSI standards and are manufactured in ISO-certified facilities. Each item undergoes rigorous testing prior to shipment to ensure optimal performance in your facility.

However, before purchasing these components, it’s important to know what signs indicate that a replacement is necessary. Often, neglecting regular maintenance leads to complications. In other cases, subpar materials from the original manufacturer might be the culprit.

Breakdown Due to Insufficient Lubrication

It’s easy to overlook something as basic as lubricating your roller chain drive. While it may seem trivial, failing to maintain proper lubrication can result in significant issues. Using the wrong type of lubricant or applying it incorrectly can lead to problems such as cushioned impact load issues or impaired heat dissipation. Ultimately, insufficient lubrication accelerates wear and tear on the roller chain, increasing the risk of sudden failure during critical production phases.

Chain Elongation

One of the most frequent causes of roller chain failures stems from elongation caused by worn-out pins and bushings. These parts degrade due to repeated articulation as they enter and exit the chain sprockets. Once these vital components begin to fail, it becomes imperative to replace them with high-quality alternatives. Unfortunately, some suppliers don’t provide the durability required to preserve the chain's lifespan. Rest assured, The Big Bearing Store offers top-notch pins and bushings tailored specifically for roller chains.

Poor Manufacturing Practices

Proper fabrication is essential for ensuring the roller chain assembly operates efficiently. This includes smoothing out imperfections on the pins via a grinding process. A clean pin surface facilitates even load-bearing pressure distribution. Similarly, bushings must undergo similar procedures to achieve greater roundness. Uneven surfaces on either component can exacerbate wear and trigger severe malfunctions.

Inadequate Heat Treatment or Preloading

Heat treatment serves as an effective method to mitigate wear and tear on roller chains. However, executing this procedure demands expertise and precision. Typically, manufacturers incorporate heat treatment during the production stage to guarantee superior quality. Such processes enhance case hardness and depth, providing enhanced wear resistance to prevent premature breakage. Before acquiring a chain part, consider checking whether it has undergone appropriate heat treatment to ensure longevity instead of frequent replacements. At our store, you won’t encounter low-quality merchandise.

Reputable manufacturers generally implement this concept during the manufacturing process of roller chains. Preloading helps address elongation concerns that contribute to accelerated deterioration of roller chains. Without preloading, the chain drive tends to elongate rapidly and continues to do so over time until it wears out completely.
