The manufacturing accuracy of Excavator oil cylinders usually needs to meet the following requirements:

Dimensional accuracy: The dimensional accuracy of each component of the oil cylinder must comply with national standards and design requirements. Especially the size parameters such as inner diameter, outer diameter, and axial roundness of the oil cylinder need to be controlled within a certain tolerance range.

Surface roughness: The surface roughness of the oil cylinder should meet national standards and design requirements, with a smooth surface, no obvious wear, burrs or other defects.

The precision of related components: The manufacturing precision of seals, piston rods, cylinder liners, and other related components of the oil cylinder is also required to ensure the sealing and service life of the oil cylinder.

Internal airtightness: Good airtightness needs to be maintained inside the oil cylinder to ensure its normal operation. During the manufacturing process, it is necessary to strictly control the machining and testing processes of the oil cylinder to prevent oil leakage.

In short, manufacturing excavator oil cylinders requires strict control of manufacturing accuracy to ensure the quality and service life of the cylinders.
