For RC drilling operations, productivity is often dictated by the reliability of the smallest components. Swivels are no exception. Harlsan Pty Ltd has developed its swivels range with a clear purpose: to reduce downtime, simplify maintenance and deliver measurable gains in drilling performance. Real-world case studies show just how significant that impact can be.

The Industry Challenge

Many conventional inlet and bearing swivels used across RC rigs are overly complex, with numerous serviceable parts and sealing systems that struggle under high-pressure conditions. Frequent reseals, maintenance delays and part failures add unnecessary downtime.

A review of industry performance benchmarks shows a recurring pattern: excessive hours spent maintaining the head assembly and regular stoppages for seal and bearing replacements. These issues directly reduce shift productivity.

What Sets Harlsan Swivels Apart:

Harlsan’s Inlet & Bearing Swivels are engineered specifically for RC drilling environments. Key advantages to drillers in the field include:

  • Reduced Part Count: Fewer serviceable components mean faster, simpler and safer maintenance.
  • High-Performance Sealing: The sealing system is built for high-air-pressure RC applications, allowing longer intervals between reseals.
  • Field-Service Support: Spare bearings, shafts and seal kits are readily available to minimise downtime.
  • Rig Compatibility: Top Inlet, Bottom Inlet and Bearing Swivel options, along with adapter flanges, allow seamless fitment to a wide variety of rigs.

Harlsan 4’’ & 4 ½’’ Bottom Inlet Swivels are designed & engineered to
handle the high air pressure required for drilling deep RC holes.

What This Means for RC Contractors:

Less Maintenance at Height: Faster servicing reduces the risks and time associated with work on the rig head.
Longer Operating Intervals: The sealing system’s durability means fewer interruptions.
Higher Rig Availability: More time drilling, less time in maintenance.
Lower Operating Costs: Smaller service kits, fewer rebuilds and reduced labour hours.
Plug-and-Play for Most Rigs: Adapter solutions simplify upgrades without major modifications.
In short, the swivel becomes a productivity driver rather than a maintenance burden.

Field Feedback:

Across multiple sites, drill crews have reported meaningful differences. One operator on a deep RC program noted that the Harlsan Bottom Inlet Swivel consistently handled higher pressures and extended reseal intervals—directly reducing downtime and improving shift output.

This aligns with the broader trend seen across Harlsan’s case studies: reliable equipment that optimizes drilling operations, ultimately increasing profitability.

Why Harlsan’s Swivels are The Driller’s Choice:

Simpler Design
resulted in easier maintenance, with fewer parts involved. 

 

Faster and simpler maintenance
meant safer maintenance and extended service periods.

Cost savings
owing to fewer parts in the service kit.

 

Faster, simpler and easier maintenance
