Rexroth L2F Series High-Pressure Bent Axis Piston Units

Product Overview: The Rexroth L2F Series is a classic Bent Axis fixed displacement unit designed to operate as either a hydraulic pump or motor. With its signature 40° bent-axis technology, the L2F series delivers an exceptional power-to-weight ratio and superior starting torque. This category features core sizes L2F12, L2F23, and L2F28, including precision configurations: L2F23R3P4, L2F28L3P4, L2F12R2P4, and L2F23R3Z4. These units are the trusted choice for construction machinery travel drives, crane winch systems, TBM auxiliary power, and various industrial open or closed-loop circuits.

Key Technical Advantages:

• Elite Energy Conversion: The bent-axis geometry minimizes mechanical friction, maintaining outstanding volumetric efficiency even under high-pressure conditions.

• Extreme Speed Capabilities: The precision-matched spherical pistons and valve plates allow the motor to handle high RPM fluctuations without compromising performance.

• Rugged Engineering: Equipped with heavy-duty bearings to withstand significant radial and axial forces, ensuring longevity in the harshest working environments.

• Mounting Versatility: Available with multiple shaft ends (such as Keyed “P” type or Splined “Z” type) and standard mounting flanges.

• Technical Spec Decoding:

  • L2F12 / 23 / 28: Denotes displacement per revolution (cc/rev).

  • R / L: Indicates Clockwise (Right) or Counter-clockwise (Left) rotation.

  • 3P4 / 3Z4: Relates to shaft configurations (P for parallel keyed shaft, Z for splined shaft) and flange mounting standards.
