Replacement / Interchange

Possible search and drawing-reference candidates:

  • 6204 open
  • 6204-2RS sealed
  • 6204-ZZ / 6204-2Z shielded
Not an automatic replacement. Match bore diameter (d), outside diameter (D), width (B), internal clearance, sealing, cage, precision, lubrication and load requirements before any substitution is approved.
