With the accelerating growth of the lithium battery and new energy industries, the demand for high-precision rolling roller (also known as roller or roll) is rising globally. Manufacturers and roll suppliers continuously innovate materials and manufacturing processes to meet increasing requirements in wear resistance, surface finish, precision tolerances, and service life.
According to GMI 2023 Report, the industrial roller market is expected to hit USD 3.6 billion by 2030, driven by fields such as lithium battery production, metallurgy, petrochemical, and water supply industries.

3. Technical Trends: Rolling Roller Parameters Visualization
Industry data shows a continuous improvement in rolling roller quality, driven by stricter requirements from battery and new energy sectors for surface finish and dimensional precision.
4. Rolling Roller Manufacturing Process Flow
Rolling roller manufacturing integrates multiple key processes, ensuring each component achieves optimum mechanical properties, durability, and surface accuracy. Industry-leading roller manufacturers adhere strictly to ISO 9001 and ANSI standards.
Standardized rolling roller production line
Material Selection: 42CrMo, 60Si2Mn, alloyed steel, and ceramic composites are commonly used for their high tensile strength and wear resistance.
CNC Machining: Offers sub-millimeter precision, ensuring roller concentricity ≤0.005mm, in compliance with ISO/ANSI standards.
Surface Coating: Advanced Cr, TiN, and ceramic coatings enhance corrosion resistance and extend service life up to 8–12 years.
Inspection & Testing: Each rolling roller undergoes NDT (non-destructive testing), hardness testing, and geometric accuracy inspection per ISO 4287 and ANSI B18.3.
High Precision: Micron-level manufacturing ( surface roughness), critical for lithium battery electrode foil production.
Durability: Service life 30–40% greater than standard rollers due to enhanced metallurgy and expert heat treatment.
Corrosion Resistance: Ideal for harsh chemical and humid environments (e.g., petrochemical and waste water handling industries), enabling smooth operation with reduced downtime.
Energy Efficiency: Advanced surface finishes and material optimization contribute to 7–10% energy savings in continuous rolling production lines.
Wide Applicability: Employed in metallurgy, new energy, lithium battery, petrochemical, and water supply sectors worldwide.

9. Rolling Roller Technical FAQ
Q1: What materials are commonly used in rolling roller for lithium battery lines?
A1: The mainstream materials include 42CrMo alloy steel, 60Si2Mn, and special ceramics, chosen for their high tensile strength, corrosion resistance, and ability to withstand repeated rolling processes. Each batch is certified with a material report and chemical composition certificate.
Q2: What is the typical surface hardness and why is it important?
A2: Surface hardness usually ranges from HRC 60–66. Higher hardness prolongs roller wear life, ensures uniform contact pressure, and maintains product thickness accuracy over long usage. XT ShuoDing's proprietary heat treatment increases this parameter by 10% over traditional processes.
Q3: How is surface roughness (Ra) controlled, and what is the standard value?
A3: Using precision CNC equipment and post-polishing, Ra is typically controlled within 0.15–0.25μm (ISO 4287). Low Ra values ensure smooth, defect-free electrode surfaces in lithium battery production.
Q4: What is concentricity, and what is the tolerance achieved?
A4: Concentricity refers to the deviation between roller axis and its bearing surfaces. Advanced roller manufacturer lines achieve ≤0.005mm, using 3D-CMM and laser alignment measurement.
Q5: Do you support customization of work rolls and intermediate rolls for different needs?
A5: Yes. Both work rolls and rolling intermediate roll types can be customized – varying dimensions, groove shapes, hardness, and surface coatings as per user line process requirements.
Q6: What are the installation and testing standards applied?
A6: Installation adheres to ANSI B18.3 and regional safety codes. Each rolling roller undergoes runout, roughness, and hardness tests before delivery, with full inspection records.
Q7: What after-sales support and quality assurance is provided?
A7: XT ShuoDing offers 12–24 months warranty, on-site technical support within 2 working days globally, and spares supply for the entire lifecycle of the rolling roller. All quality claims handled within 48 hours.
