CAD (0) ▾

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 (r_{as max}).
Meets Military Standard MS 51961.
