Rulmeca operates a Service centre fully dedicated to the repair and assembly of Motorized Pulleys
Sometimes the difficult working conditions of the plant results in a lateral movement of the belt. In this case a self-centering troughing set is used which acts in a way that corrects the belt tracking and maintains it constantly in the central position. The self-centering troughing set is designed as a series of rollers arranged in a trough positioned onto the supporting transom which itself is fixed to a slewing ring which permits rotation. The slewing ring (a large ball bearing) permits a rotation limited to 5-8 degrees and is sized in proportion to the vertical loading; a tapered roller bearing assembled to the shaft of the slewing ring, absorbs any side forces or overturning pressures. The installation of the self-centering troughing sets is advised to be positioned on the upper strand rather than the return section, and used only when the working conditions require.

Plus
Rulmeca’s self-aligning troughing and return sets are engineered for high efficiency and long-term reliability. These sets are specifically designed to maintain optimal belt alignment under the most challenging conditions, reducing belt tracking issues and ensuring the conveyor system operates smoothly. The advanced design of the sets, featuring a precision slewing ring mechanism, ensures consistent self-aligning capabilities even in high load or extreme environmental conditions. This robust construction guarantees long-lasting performance, minimizing the need for frequent maintenance and downtime
The self-aligning systems are equipped with a large, hardened slewing bearing that features a full complement of balls, providing exceptional durability and resistance to wear. This ensures a long functional life for the conveyor system, even in the most demanding applications. The slewing bearing’s advanced design effectively absorbs radial and axial forces, enabling the self-aligning set to maintain belt stability without compromising performance over time. This key feature contributes to a reduction in operational costs by extending the lifespan of both the return sets and the conveyor system as a whole
Rulmeca’s self-aligning troughing and return sets are fully compatible with standard carrying or return rollers without the need for rubber rings. This configuration simplifies the design and reduces maintenance requirements while still offering superior performance in terms of alignment and support. The use of standard rollers ensures that the system is easy to integrate into existing conveyor setups, offering a cost-effective solution that maintains the required belt support without compromising on durability or functionality.
