Types of Needle Roller Bearing

• 1. Drawn Cup Needle Roller Bearings
  • Have a thin-walled outer ring (cup) pressed from sheet steel.
  • Compact, lightweight, and can handle high loads.
  • Common in automotive and industrial applications.
• 2. Solid Needle Roller Bearings
  • Made with a machined outer ring.
  • Stronger and more rigid than drawn cup types.
  • Suitable for heavy-duty applications.
• 3. Needle Roller and Cage Assemblies
  • Consist of only rollers and a cage, without inner or outer rings.
  • Compact and designed to fit directly into housings or shafts.
  • Ideal when the shaft and housing can act as raceways.
• 4. Thrust Needle Roller Bearings
  • Designed to handle axial loads (in one direction).
  • Use a cage with needle rollers arranged radially.
  • Often used in gearboxes and clutches.
• 5. Combined Needle Roller Bearings
  • Combine a radial needle roller bearing with a thrust bearing.
  • Handle both radial and axial loads simultaneously.
• 6. Needle Roller Bearings with Inner Rings
  • Include a machined inner ring when the shaft surface cannot serve as a raceway.
  • Provide flexibility in design and durability.
• 7. Cam Followers (Needle Roller Type)
  • Special type with a thick outer ring.
  • Designed for high radial loads and shock loads in cam and track systems.
