Chains and sprockets are some of the hardest-working components on a bakery line, operating under high stress day in and day out. And yet, they’re often overlooked – until something goes wrong, that is! One of the biggest threats to their longevity and performance is inadequate lubrication. Let’s take a look at some of dangers of dry chains, and demonstrate why bakers should tackle this issue before it’s too late.
When chains run dry, the result is metal-on-metal contact between rollers, pins, and sprocket teeth. This generates excessive friction, accelerates wear, and increases the risk of unexpected failure. This can lead to a host of costly consequences: noisy operation, reduced efficiency, and expensive unplanned downtime.
Another key issue tied to poor lubrication is chain elongation, commonly known as chain stretch. As the internal parts of the chain wear, the entire chain lengthens, causing it to mesh poorly with the sprockets. This misalignment not only wears down sprocket teeth unevenly but can also cause the chain to slip, or worse, break, resulting in potentially catastrophic damage.
Dry chains are also more likely to develop stiff or kinked links, which hamper smooth movement. Left unchecked, the friction and heat buildup can cause complete chain failure, damaging surrounding equipment and creating serious safety hazards. In humid bakery environments, a lack of lubrication also makes chains more susceptible to rust and corrosion.
How to Prevent These Issues:
- Follow the manufacturer’s lubrication schedule and always use the recommended lubricant.
- Clean chains and nearby components before lubricating to prevent grit and debris from accelerating wear.
- Conduct regular inspections for signs of wear, stretch, stiffness, or corrosion.
Taking just a few minutes for proper lubrication and inspection can mean the difference between a smooth-running production line and a costly breakdown. It’s a small effort with big rewards: improved reliability, lower maintenance costs, and a longer life for your equipment.
