Carbon Steel Shell Rubber Cover Jumbo Press Roll
Carbon Steel Shell Rubber Cover Jumbo Press Roll Introduce
The vacuum pressure roller shell is covered with rubber with a thickness of 30-40mm. The advantage of encapsulation is to make the pressure distribution uniform, reduce the wear of the felt, and increase the pressure of the press line.
Production practice shows that the axial and circumferential center distance of the holes on the vacuum pressure roller is smaller, and the number of holes is larger, which can significantly improve the dehydration effect of the vacuum pressure roller, thereby effectively eliminating the embossing phenomenon and extending the service life of the blanket. The hole diameter of the vacuum pressure roller should be properly selected to ensure that the roller has a sufficient amount of dehydration, but also to consider that the opening will affect the strength of the roller and leave "shadow marks" on the paper. The hole diameter of the vacuum pressure roller is generally about 4mm.
Carbon Steel Shell Rubber Cover Jumbo Press Roll Feature
Each part of the roll is designed to maintain efficiency through specific criteria. Some of the innovative features of each of these parts are listed below:
Bearings: Spherical roller bearings are mounted on tapered seats with hydraulic removal provisions. The bearings are designed to meet L-10 (120,000 hours) lifespan through the applicable loads and speeds.
Deckles Adjustments: Our standard deckles are opposing screw type mechanical adjustments.
Efficient Air Flows: All of our suction rolls are designed to achieve the proper air flow efficiency from the shell through the suction box and out the suction elbow.
Internal Bearings: We offer an internal bearing design that utilizes an inner ring rotation spherical roller bearing. The bearing is mounted on a tapered seat journal for easy installation and removal.
Internal Suction Box Seals: The seal between the suction box and the shell inside diameter is accomplished with rubber graphite seal strips (plain and silencer), end deckles with custom stainless steel loading springs, and air tube loading assemblies.
Showers: All rolls come standard with a seal strip lubrication shower and a cleaning shower.
Split Front Housing: Both models offer a split front housing that enables the bearings and vacuum connection to be accessed easily.
Suction Box Material: Our suction rolls are provided with stainless steel suction boxes unless a carbon steel painted box is preferred.
