300, and after precision processing, they undergo intermediate frequency quenching with a hardness of HRC45-55. In accordance with the JB/ZG4289-86 standard for rolling steel, the stiffness complies with (1/7001/1000) L, where L refers to the distance between the centerlines of the two side frames.
(2) The rotation of the work roller: the hydraulic motor is connected to the planetary gearbox, and then the torque is transmitted to the work roller.
Our advanced four-roller rolling machine is driven by the upper roller, as depicted in the diagram below. The upper roller functions as the primary driving roller, powered independently by a hydraulic motor seamlessly coupled to a high-power planetary gearbox (linear coupling), eliminating the need for intermediate gear transmission. This design represents the pinnacle of energy-efficient driving methods. The hydraulic motor features an instant brake mechanism, ensuring precise stopping of roller rotation in the pre-bending state.

3.1.2Bearings at both ends of the work rollers
Each end of our work rollers is equipped with two premium roller bearings, sourced from Wafangdian, a renowned brand in China. These high-quality bearings ensure exceptional performance and durability.
Each roller in our advanced four-roller machine is equipped with highly durable, industry-recommended self-aligning roller bearings. These bearings effectively counteract pressure from shaft misalignment during roller shaft rotation, allowing each shaft to move freely and flexibly. This design avoids scratches and cracks on the rollers. The internal structure of these bearings permits them to withstand roller shaft misalignment and tilt. When subjected to fixed outer cover forces, this foldable mobility prevents damage to the roller shaft from reverse forces.
Our self-aligning bearings offer significant advantages. Regardless of shaft deviation, the roller shaft smoothly and safely realigns, returning to its original position. Conical rolling demands stringent tolerances, requiring the roller shaft to tilt and manage unbalanced loads. These loads place significant pressure on the bearings. With self-aligning bearings, the load is directed into an axial mode, controlling the impact of folding and ensuring smooth, safe self-rotation. Our innovative design incorporates two self-aligning bearings on each roller shaft, enhanced with 'permanent lubrication technology.' This feature eliminates the need for frequent lubrication, ensuring optimal performance throughout the product's lifespan.
