TECHNICAL NOTES

Conversation-specific knowledge extracted from the bearing hole dimensioning discussion.

EXTRACTED KNOWLEDGE / HOW-TO FROM CONVERSATION

QUESTION / CONTEXT: i have a Oil-Embedded 841 Bronze Sleeve Bearing with an od of .627 that need put in a stainless steel block, how should i dimension the hole in the stainless steel block

  1. *Ø0.6245 ±0.0005 in
  2. Best drawing callout: Ø0.6245 ±0.0005
  3. Acceptable housing range: 0.6240–0.6250
  4. Resulting interference: about 0.001–0.003 in with the bearing OD tolerance shown as +.000 / -.001. [embedded media omitted]
  5. Put a small lead-in chamfer on the hole so you do not shave the bearing during install.
  6. Press it in, do not hammer it.
  7. Because it is stainless, I would stay near the middle of that tolerance, not the tight extreme, unless the bearing maker gives a more specific fit for your wall thickness and load.
  8. *Ø0.625 ±0.001
