RETAINER PLATE - ERL-130B-RP-21-20NNN

Precision-engineered retainer/set plate for Danfoss Sauer ERL-130B axial piston pumps (Series 45, RP-21-20NNN). This plate holds and aligns the piston shoes in the cylinder block, ensuring stable movement and correct positioning during pump operation.

Application:

• Designed for Danfoss ERL-130B pumps

• Used in mobile hydraulics, heavy machinery, and industrial hydraulic systems

• Works with piston shoe assembly, cylinder block, and ball guide

Technical Details:

• Pump Model: ERL-130B (RP-21-20NNN)

• Material: Hardened, high-strength alloy steel

• Function: Retains piston shoes securely in the rotating group, minimizing vibration and wear

Purpose:

The retainer plate ensures that piston shoes remain properly seated and guided within the rotating group, preventing misalignment, reducing friction, and enhancing pump efficiency and service life.
