3. Cylindrical Roller Bearing Manufacturing Process

1 Material Selection:  Premium alloy steels: GCr15 (ISO 683/17), 42CrMo, or stainless (for high corrosion resistance), chosen for fatigue life and strength.
↓
2 Forging & Pre-Machining: Billets are forged and normalized, reducing voids. Pre-machining achieves closer tolerances, ensuring optimal geometry.
↓
3 CNC Precision Turning: Inner & outer rings, rollers, and cages are CNC-turned with ISO P6/P5 tolerance grades. This minimizes runout and improves load distribution.
↓
4 Heat Treatment: Through-hardening (58-64HRC, measured by Rockwell C), achieving high wear resistance and durability.
↓
5 Grinding & Superfinishing: Rings/rollers are ground and superfinished (Ra ≤ 0.20µm). Lower surface roughness reduces friction, raises lifespan.
↓
6 Assembly: Rollers are inserted in cages; inner/outer rings indexed and matched for precision. Automated and manual QC per ISO 492 and ANSI/ABMA standards.
↓
7 Testing & Traceability: Inspection of dimensional accuracy, vibration (per ISO 15242), and non-destructive testing. Marked for traceability, batch tracking, and final packaging.

4. Core Advantages of Cylindrical Roller Bearings

  • High Radial Load Capacity: Optimized roller geometry & increased contact area outperform ball designs in heavy loads and shock resistance.
  • Extended Service Life: Standardized heat treatment, superfinishing, and advanced materials provide average L10 life above 100,000 hours under rated conditions (per ISO 281).
  • Versatile Configurations: Double-row cylindrical roller bearing, single-row, and axial/thrust types support a range of radial & moderate axial load requirements.
  • Reduced Friction & Energy Loss: Rolling contact design (point contact/minimized slip) produces lower friction torque than other roller architectures.
  • Corrosion/Sealing Options: Stainless/ceramic variants plus contact or non-contact seals make these suitable for extreme environments.
  • Customization: Bore/OD/width, chamfer radii, lubrication grooves, and cages can be engineered to client specification.
Typical Application Sectors: Steel & metallurgy | Pumps & compressors | Petrochemical | Electric motors | Railways | Water treatment plants

11. FAQ: Cylindrical Roller Bearing Technologies

Frequently Asked Technical Questions
Q1: What is the standard material for cylindrical roller bearings?
A: The standard is GCr15 steel (ISO 683/17 equivalent to SAE52100), offering high load fatigue and wear resistance. For corrosive or high-temp environments, 42CrMo, stainless (AISI 440C/316L), and Si3N4 ceramic options are increasingly used.
Q2: How does a double row cylindrical roller bearing compare to single row types?
A: The double row variant (e.g., NN, NNU) offers higher radial load ratings (up to 1.8x that of single row) and better load distribution, making it ideal for heavy machinery and gearboxes.
Q3: What are ISO/ANSI fitting tolerances for cylindrical roller bearings?
A: Per ISO 492/ANSI ABMA 20, typical ring accuracy grades are P0 (normal), P6 (fine, 9µm out-of-round), P5 (precision, 5µm). Installation fits depend on shaft/envelope but often use K5/J6 for interference.
Q4: What is the difference between open and sealed bearing roller cylindrical types?
A: Sealed types include metal/rubber contact seals to block dust, water, and lubricants loss, enhancing service intervals. Open types are used in ultra-clean/controlled or lubricated environments.
Q5: Which lubrication is preferred for high-speed applications?
A: Lithium-based grease (NLGI #2) or synthetic oil with extreme pressure (EP) additives and low viscosity is recommended, together with deep-grooved cages for effective oil/grease distribution.
Q6: What installation standards should be followed?
A: ISO 15243 provides failure root-cause analysis; mounting uses ISO 199 (taper bore) or ISO 2982 (cylindrical bore). Proper alignment, press-fit tools, and avoidance of hammering are critical.
Q7: Can cylindrical roller bearings handle axial forces?
A: Standard designs mainly take radial load, but NJ, NUP, and thrust (axial) types specifically support combined or pure axial loads—essential in gear drives and vertical applications.
