Cylindrical Roller Bearings

Cylindrical Roller Bearings primarily withstand radial loads with limited axial load capacity. Their design features line contact between rollers and raceways, offering high rigidity and large contact areas suitable for high-speed, heavy-load applications. Bearings are available in single-row, double-row, or multi-row configurations, with separable inner/outer ring designs for easy installation and maintenance.
Structural Features
Line Contact Design: Reduces unit pressure and enhances load capacity through linear roller-raceway contact.
Low Friction: Minimizes rolling resistance for high-speed rotation.
Separable Structure: Simplifies installation via detachable inner/outer rings (select models).
Precision Cages: Stamped or solid cages ensure uniform roller distribution.

Cylindrical Roller Bearings
Product Types
Application
The bearings can be used in the following industries
  1. Industrial Machinery
    • Heavy-duty gearboxes, motor rotor supports
    • Conveyor rollers, printing press rolls
    • CNC machine tool spindles, precision boring machine feed systems
  2. Automotive & Transportation
    • Wheel hub bearings, transmission gear shafts
    • High-speed train wheel set bearings, locomotive traction motors
    • Construction machinery (excavators, cranes) travel mechanisms
  3. Aerospace
    • Aircraft engine turbine shaft supports
    • Helicopter main rotor drive systems
    • Spacecraft solar panel deployment mechanisms
  4. Energy & Environmental Protection
    • Wind turbine main shaft bearings
    • Hydropower turbine supports
    • Industrial fans and pumps
  5. Precision Instruments
    • Semiconductor wafer inspection equipment
    • Optical lens focusing mechanisms
    • Laser cutting machine rotary tables

Selection Criteria

  1. Load Characteristics: Prioritize radial load capacity; verify axial load compatibility.
  2. Speed Limits: High-speed applications require precision cages (e.g., copper alloy) and low-friction coatings.
  3. Installation Space: Choose single-row or multi-row designs based on shaft/housing dimensions.
  4. Lubrication Method: Grease lubrication for low speeds; oil lubrication for high-speed/high-temperature scenarios.
  5. Environmental Compatibility: Stainless steel for corrosive environments; ceramic rollers for high temperatures.

Notes

  • Avoid excessive axial loads; pair with thrust bearings if necessary.
  • Ensure coaxial alignment during installation to prevent uneven wear.
  • Regularly inspect clearance and adjust preload based on operating conditions to balance rigidity and lifespan.
