Cylindrical Roller Bearings

Description

Main types
1. Cylindrical Roller Bearings
• Feature: Rollers and raceways have line contact, providing higher load capacity than ball bearings.
• Can support large radial loads, and some designs can also accommodate limited axial loads.
• Common types: NU, NJ, NUP, N series, suitable for various axial positioning requirements.
• Applications: Machine tool spindles, gearboxes, electric motors, large wind turbine main shafts.
2. Spherical Roller Bearings
• Feature: Double-row rollers with strong self-aligning ability, can absorb shaft misalignment and installation errors.
• Extremely high load capacity, suitable for impact and heavy loads.
• Applications: Mining machinery, steel equipment, paper machines, conveyors.
3. Needle Roller Bearings
• Feature: Long, thin rollers, small radial space but high load capacity.
• Compact structure, suitable for limited space applications.
• Applications: Gearboxes, automotive components, light industrial equipment.
