lube free self lubricating chains packagingFeeding, loading, wrapping, overwrapping and collating in an environment where the roller chain gets contaminated by the product being packaged requires precisely timed and measured movements.  Rotary heads and revolving carousel product movement are often controlled by roller chain. Cleaning and maintenance can be challenging due to space restrictions which makes lubrication and cleaning roller chain very difficult. Roller chain working in packaging applications often operate in high temperatures and poor lubrication is often the root cause of premature chain failures in such environments.

Contamination of the final product from oil transfer from the roller chain can result in costly rejected products at the end of the process.  Lubrication will also attract fine cardboard and paper dust onto the roller chain surface preventing any additional chain lubricant penetrating to the vital load bearing sections of the chain (between the articulating link plates and the chain pins, roller and bushes). The airborne dust also mixes with the internal lubricant forming an abrasive paste resulting in accelerated wear of the bearing surfaces.

Even a small amount of elongation to roller chain lengths used on packaging machines can result in misaligned and badly packaged product and stopping production to adjust and tension roller chains can be very costly and time consuming. 

Lube free chain is therefore without doubt a great option for the packaging industry.

We have three options for maintenance free self-lubricating chains, often referred to as lube free chain, sintered bush roller chain (SLR chain), plastic combination roller chain (PC chain) and sealed for life roller chain.

The strength and durability of these lubefree chains make them a good replacement for standard roller chain drives or conveyor chains wherever lubrication must be carried out frequently, is difficult or time-consuming and where product contamination with it’s resultant costly downtime and increased costs must be avoided.

Our lube free roller chains have been used in many card, paper and plastic packaging applications.
