1. Product Overview

This product isDanfoss 51 Series Axial Piston MotorsofCore internal componentsMainly includesCylinder blockandplunger assemblyThe 51 series motors are widely used in the drive or hoisting systems of various mobile machinery and industrial equipment. When a motor experiences internal leakage and decreased efficiency due to prolonged use, replacing this core assembly is a key maintenance method to restore its performance.

2. Core Features

High-precision matchingThe cylinder block and plunger adopt...Spherical fitThis ensures good contact and reliable sealing under high pressure, high speed and deflection conditions, reducing internal leakage.
wear-resistant materialsThe cylinder block is usually made of high-strength alloy material, and the plunger head is made of special wear-resistant material (such as copper-based or special composite material) to withstand high loads and friction and extend service life.
Recovery performanceReplacing the worn cylinder block and plunger can effectively solve the problem of internal leakage in the motor.Reduced output torque, unstable speed, and system overheatingIssues such as restoring it to a performance level close to that of a new part.
Model coverage is completeThe accessories are suitable for various models and displacements (060 to 250) under the 51 series, meeting the maintenance needs of different equipment.
