Dual - Row Configuration

  • Face - to - face (DF) or back - to - back (DB) arrangements enable handling of bidirectional axial and radial loads, offering 40% higher rigidity than single - row bearings.

Nylon Retainer Benefits

  • Lightweight design (35% lighter than metal retainers) reduces inertia for high - speed performance.
  • Self - lubricating properties lower friction (μ=0.1-0.2), extending service life and minimizing maintenance.
Application
The bearings can be used in the following industries
  • Automotive: Transmission input shafts, wheel hub motor bearings
  • Medical: CT scanner gantries, dental implant spindles
  • Industrial Machinery: High - speed centrifuges, printing press drives
