Our Solutions

Timken Fafnir mounted ball bearings resist corrosion and perform reliably in high speed operations. Multiple locking options are available to ensure the bearing is secure to the shaft aligned properly for optimal performance. Locking options include: 

  • Set Screw Locking Collar – Set screw locking mechanism is easy to install and well-suited for reversing applications and normal loads.
  • Eccentric Locking Collar – This self-locking collar eliminates the need for locknuts, washers, shoulders, sleeves and adapters. They are ideal for unidirectional applications, providing a secure, tight fit with excellent vibration resistance.
  • Concentric Locking Collar – This locking option provides superior gripping strength, reducing vibration at high speeds and minimizing shaft damage.

Benefits

  • Reduced maintenance with easy installation and greased-for-life options minimize service requirements
  • Extended bearing life due to superior sealing and lubrication reduce wear and contamination 
  • Improved reliability by handling reversing loads, axial loads and high-speed applications effectively 
  • Broad product range with assemble-to-order options
