Rulmeca operates a Service centre fully dedicated to the repair and assembly of Motorized Pulleys
In demanding industrial environments, conveyor belts are often subjected to variable loads and challenging operating conditions that can cause lateral movement, leading to misalignment and reduced efficiency. To address this issue, self-centering troughing sets are used to automatically correct belt tracking and maintain the belt in a stable and centred position.
These sets consist of a series of rollers arranged in a trough configuration, mounted on a transom connected to a slewing ring that allows limited rotation - typically between 5 and 8 degrees - to accommodate variations in vertical loading. The design also incorporates tapered roller bearings, which enhance performance by absorbing side forces and reducing wear.
Designed for installation on the upper belt strand, these self-centering troughing sets ensure smooth and consistent belt operation even under fluctuating conditions. For optimal performance, it is recommended to install them approximately 15 meters from the pulley and at intervals of 30 meters along the conveyor line. Available in three models:
These items are easily interchangeable with standard transoms, making them adaptable for both new installations and retrofitting existing systems. In addition, beyond improving belt tracking, self-centering troughing sets enhance overall operational reliability by maintaining the belt in its proper position, reducing the risk of belt edge damage, spillage, and downtime caused by misalignment. This results in smoother material flow and lower maintenance needs, becoming a cost-effective solution.

Our self-aligning troughing and return sets are engineered to deliver maximum efficiency and durability, ensuring consistent precision and optimal performance in conveyor bel tracking. The robust design, made from high-quality materials, allows these sets to perform reliably across a wide range of industrial applications and challenging environments. They are suitable for both standard and reversible conveyors, maintaining precise belt alignment and preventing operational inefficiencies caused by lateral belt movement. Ideal for high-load applications, these sets ensure optimal conveyor performance even under the most demanding conditions.
The long-lasting efficiency of Rulmeca self-aligning sets is achieved through the incorporation of large, hardened slewing bearings with a full complement of balls. This advanced bearing design increases load-bearing capacity while minimizing friction, resulting in smoother operation and extended system lifespan. The slewing bearing structure also enables smooth rotation while absorbing side forces, preventing wear and ensuring reliable, consistent performance over time. This design is especially advantageous in high-impact applications where durability and longevity are crucial.
A key feature of our self-aligning troughing and return sets is the use of standard carrying or return rollers, which operate efficiently without rubber rings. These rollers provide excellent belt support and uniform load distribution while maintaining a simplified design that reduces maintenance complexity.
The absence of rubber rings minimizes material buildup and contamination risks, making these rollers ideal for applications with low adhesion concerns. Their straightforward design ensures easy integration into existing conveyor systems, reducing installation time and long-term operational costs, perfect for efficient and reliable conveyor operation.
