The Bedford 42-4191 is a compatible replacement for Graco parts 178207 and 178-207 — the piston bearing used in Graco spray equipment. This bearing guides its moving shaft or rod, taking the side-loads so the precision surfaces around it do not. A worn bearing lets the rod run off-center, which accelerates packing and cylinder wear well beyond the cost of the bearing. Compatible with Graco GH 130 (2014+) and LineLazer V 130 HS.

Common reasons for replacement:

  • Scoring visible on the bearing surface at teardown
  • Renewed during a fluid-section or drive rebuild
  • Play or knock in the rod as bearing clearance opens up
  • Accelerated packing wear from an off-center rod

Manufactured to OEM-equivalent dimensions for proper fit and performance.
