PRODUCT DESCRIPTION

743J9MT-2N

  • Stainless Steel Construction: Grade 17-4 PH material resists corrosion and fatigue over a wide temperature range.

  • Corrosion-Resistant Finish: Passivated coating protects against moisture, hydraulic fluids, and cleaning agents.

  • High Tensile Strength: Withstands axial loads up to 1,200 N without deformation.

  • Lightweight Design: Weighs less than 10 g, minimizing added mass to rotating and structural assemblies.


  • Secures piston rods and bearing housings under high load cycles.

  • Retains couplings and shafts in accessory gearboxes.

  • Locks the spool and sleeve components to prevent axial movement in the hydraulic valve.

  • Prevents shaft migration in gyro and pump assemblies.


  • What tools are required to install this retaining ring?

Use standard snap‑ring pliers sized for the ring’s nominal diameter.

  • How do I verify proper installation?

Ensure the ring snaps fully into its groove. A visual check that it sits flush and doesn’t rotate under light finger pressure confirms correct seating.

  • How should I inspect the ring during maintenance?

Look for cracks, nicks, or corrosion spots. Measure ring diameter to ensure it remains within tolerance and replace if deformed.
