1. Product Overview

This product isthe core heart component maintenance kit for Danfoss H1B series closed axial piston motorsofthe core heart component maintenance kit. The H1B series motors are widely used in various types of mobile machinery and industrial equipment. When the motor experiences internal leakage, reduced efficiency, weakness, or abnormal noise, this kit usually needs to be replaced to restore its performance.

2. Details of Core Components

Cylinder Block:
- Material: Usually made of high-lead bronze alloy, it has excellent anti-seizure and anti-friction properties.
- Process: The inner hole is precisely honed to form the best fit clearance with the piston; the spherical or flat surface (depending on the specific model) is paired with the valve plate to ensure sealing under high pressure.
Piston / Plunger:
- Material: High-strength alloy steel with a hardened surface.
- Process: The piston head is usually spherical or has a slipper and contacts the swash plate; the piston rod precisely fits the cylinder bore to achieve reciprocating motion.
Drive Shaft:
- Material: High-strength alloy steel forging.
- Process: The spline part is induction hardened and has strong wear resistance; the bearing position is precision ground to ensure rotational accuracy.

3. Core Features

Danfoss Original Standard: All accessories are strictly manufactured according to the material, heat treatment hardness (usually HRC 58 - 62), and geometric tolerances of the Danfoss H1B series drawings to ensure perfect interchangeability with the original motor.
Complete Set of Precise Matching: The cylinder block and piston are grouped and selected as a set of friction pairs to ensure consistent clearance, avoiding early wear or internal leakage caused by improper clearance, thus restoring the volumetric efficiency of the motor.
Covers the Full Range of Displacements: One set of products covers the full range of specifications fromH1B060 (small displacement) to H1B250 (large displacement), which is convenient for inventory management and maintenance use.
High - Cost - Performance Maintenance Solution: Compared with replacing the entire motor assembly, replacing this core kit can save a large amount of maintenance costs and is an economical and effective solution to restore the performance of the H1B motor.
