  • Clearance fit suggested for outer ring when housing is stationary relative to load.
  • Tight transition fit suggested if housing rotates relative to load.
  • Consult your Timken representative for oscillating applications (e.g., low radial-clearance concerns).
  • Unmarked end of outer ring should be assembled against housing shoulder to clear maximum allowed housing fillet (ras max).
  • Meets Military Standard MS 51961.
