Four-row cylindrical roller bearing FC4462157M/P5 FC6084240M/P5 for lithium battery electrode rolling mills

Four-row cylindrical roller bearings for lithium battery electrode roll presses

Our four-row cylindrical roller bearing for lithium battery electrode calendering presses is an ultra-heavy-duty, high-precision component custom-engineered for maximum radial load capacity and zero-deflection roll support in high-pressure electrode compaction systems. Featuring four rows of high-precision cylindrical rollers in a rigid, compact design, it delivers maximum load distribution and ultimate radial stiffness for precise electrode density control.

Features and Advantages:

Ultra-High Radial Load Capacity & Maximum Rigidity: Designed with four densely packed rows of precision rollers, offering maximum contact line length. This provides extreme radial load ratings and high structural rigidity under intense hydraulic pressing forces, preventing roll journal flexing and chatter marks.

Sub-Micron Radial Runout & Micro-Level Precision: Precision-machined to P5/P4 tolerances with micro-geometry optimized raceways and matched roller sets. Delivers ultra-low radial runout and minimum dimensional tolerances, ensuring exact gap consistency across the entire width of the electrode foil.

Controlled Thermal Expansion & Low Heat Generation: Utilizes vacuum-degassed high-purity steel with advanced thermal stabilization. Optimized internal clearances and precision cages allow smooth axial float and heat dissipation during continuous 24/7 high-speed calendering, preventing raceway binding and pre-load loss.

Cleanroom & Contamination Control: Integrates high-performance low-friction seals and cleanroom-compatible synthetic lubricants. Prevents particulate shedding, guards against external electrode dust ingress, and ensures strict ISO Class 5 cleanroom compliance.

Applications:

Four-row cylindrical roller bearings are the primary shaft support choice for heavy-duty lithium-ion battery electrode production. They serve as the core load-bearing components on main upper and lower roll journals of high-pressure electrode calendering presses, continuous high-density roll-pressing systems, and heavy-duty foil compaction machinery.
