Carbon Steel Shell Rubber Cover Jumbo Press Roll

The vacuum pressure roller shell is covered with rubber with a thickness of 30-40mm. This encapsulation provides uniform pressure distribution, reduces felt wear, and increases press line pressure.

Production experience shows that smaller axial and circumferential hole spacing with more holes significantly improves dehydration efficiency, effectively eliminating embossing while extending blanket service life. The optimal hole diameter (typically about 4mm) balances dehydration capacity with roller strength and prevents paper shadow marks.

• Deckles Adjustments: Standard opposing screw-type mechanical adjustments.
• Air Flow Efficiency: Optimized design for proper air flow from shell through suction box to elbow.
• Internal Bearings: Inner ring rotation spherical roller bearings on tapered seat journals for easy maintenance.
• Suction Box Seals: Rubber graphite seal strips with stainless steel loading springs and air tube assemblies.
• Showers: Standard seal strip lubrication and cleaning showers included.
• Split Front Housing: Enables easy access to bearings and vacuum connections.
• Suction Box Material: Standard stainless steel construction (carbon steel painted option available).
