Douglas Rulmeca is proud to be featured in the October 2025 issue of Pit & Quarry Magazine, which explores the engineering behind modern idler performance in the aggregate industry. The article highlights insights from Douglas Rulmeca President and CEO Paul Ross and Corporate Engineering Manager Simone Costa of Rulmeca Holding, who discuss how advanced sealing systems, precision machining, and high-efficiency bearing designs are redefining reliability and uptime for conveying systems across quarries.
Why Idler Performance Matters
In the aggregate industry, conveyors are the backbone of production — and idlers play a critical role in keeping them running smoothly. The Pit & Quarry feature explores how design, sealing, and bearing innovations help producers minimize downtime, improve safety, and reduce total cost of ownership.
Engineering for Durability
Douglas Rulmeca’s idlers are built for harsh quarry environments, where dust, moisture, and impact are constant challenges. As noted in the article, features such as multi-stage sealing systems, sealed-for-life ball bearings, and counter bored tubing work together to extend component life and improve energy efficiency.
Precision and Sustainability
By minimizing rolling resistance and maintaining precise alignment through CNC machining, Douglas Rulmeca idlers enhance both performance and sustainability. Lower friction means reduced energy use per ton conveyed — an important factor as producers aim to cut operating costs and emissions.
Backed by Global Expertise
As part of the global Rulmeca Group, Douglas Rulmeca combines U.S. manufacturing with international engineering excellence. The company continues to innovate with idler solutions that meet CEMA standards and deliver consistent, reliable results for producers around the world.
