drill rig chain

Maintaining drill rig chains professionally

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.”

Schaeffler seals the deal with top of line sealed bearings

Bearing failures on mine sites occur most often due to contaminants, such as aggregates, iron ore, coal or any mining material penetrating the seal of the housing. This is aggravated by poor maintenance of the equipment, insufficient or excessive lubrication, and incorrect installation.

On a mine site, water is often used to wash down equipment, leaking through the bearings, turning dust into mud, and hindering performance on production lines.

Sealed spherical roller bearings, as Tony Tormey, BSC’s product manager for industrial bearings explains, are the “last line of defence” where bearings are used in dust-prone applications in mining, such as in conveyor pulleys or conveyors in cement mills.

“Bearings in harsh conditions like mining generally have three barriers, which is the housing, the grease and the seal on the bearing. You can also fill the cavity in the housing with grease, which will act as another barrier,” Tormey said. “But despite all that, water or dust can still penetrate the housing, and that’s where sealed spherical roller bearings provide an extra layer of protection to the bearing.”
