When it comes to keeping heavy-duty conveyor systems running smoothly, not all idlers are created equal. The Douglas/Rulmeca CEMA E+ Idlers stand apart for their engineering precision, superior durability, and ability to handle the most demanding applications. Built to exceed standard CEMA E specifications, these idlers are the go-to choice for operations that demand reliability under intense loads and harsh conditions.
Engineered for Unstoppable Performance
Every CEMA E+ Idler is designed with longevity and performance in mind. From the inside out, Douglas focuses on details that prevent premature wear and costly downtime. Precision-grooved ball bearings ensure smooth rotation, while counter-bored tubing protects weldments from damage. These features work together to maintain proper alignment and reduce friction, even in environments where other idlers might fail.
Advanced Sealing Systems for Total Protection
Dust, water, and debris are a conveyor system’s biggest enemies — but CEMA E+ Idlers are built to fight back. Each unit features a grease-filled labyrinth seal that blocks contaminants before they reach the bearing, as well as an external wiper seal for extra defense against dirt and moisture. Internal seals add another layer of protection, ensuring consistent performance and minimal maintenance over time.
Heavy-Duty Frames That Outlast the Competition
The strength of a conveyor system depends on its frame. Douglas/Rulmeca uses laser-cut steel for its CEMA E+ and F frames, ensuring precise dimensions and exceptional durability. The open-design foot bracket allows for flexible mounting, while the self-cleaning base prevents material buildup that can cause belt wear. Each frame is finished with a corrosion-resistant powder coating, protecting against rust and weather exposure in the most punishing environments.
Designed for Real-World Demands
CEMA E+ Idlers are built for industries that never slow down — mining, coal and power generation, cement, and aggregate operations. They’re engineered to carry heavy loads, absorb impact, and maintain belt tracking over long distances. Every element, from the retaining ring that locks bearings in place to the stone guard that keeps rocks from lodging in the roll, serves a purpose: to keep material moving efficiently and safely.
