Drill rig chains work in some of the most challenging environments. High loads, abrasive conditions and exposure to dirt and dust mean these chains have a shorter service life than most other roller chains.
As BSC National Product Manager for Power Transmission, Troy Markland, explains, “roller chains are typically designed to work approximately 15,000 hours in general industrial applications when meeting standard duty conditions, horsepower guidelines and general good PM practices.
“But in heavy-duty applications such as in drill rigs, their service life can be much shorter. That said, if you are getting very short life out of your chains or if the chains are elongating after only a few weeks or months, that’s a sign your roller chains are not suitable for the job,” Markland says.
As an external drive professional with nearly 30 years of experience at BSC, Markland’s recommendation for heavy-duty applications such as drill rigs is the Diamond HS series chain.
“The Diamond high strength chains are at the very top end of strength when it comes to roller chains,” Markland says.
“The HS series chains have been made with increased fatigue strength which allows the chains to handle the shock loads. These chains also use solid bushings and rollers that allow for extended wear life.”
