A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory reference, the operating pressure range is 1.0 to 1.6 MPa. However, this is a reference range; the actual pressure rating depends on the specific model and application. Always verify with the legal manufacturer or supplier.
The rod is typically made of chrome-plated steel or hardened alloy steel. The material grade may be 45# or 40Cr as per GB/T 699. The chrome plating thickness ranges from 20 to 50 µm, and the rod hardness is HRC 50-60. Confirm the exact material and treatment for your application.
Hydraulic fluid pressure acts on the piston surface, creating a force that moves the piston and rod linearly within the cylinder bore. The rod transmits this force to external components. The piston seals against the bore to maintain pressure, and bearing surfaces ensure alignment.
Key parameters include cylinder bore diameter (40-200 mm), rod diameter (20-100 mm), stroke length (100-2000 mm), operating pressure (1.0-1.6 MPa), operating temperature (-20 to 80°C), surface roughness (0.2-0.4 µm Ra), straightness tolerance (0.05-0.10 mm/m), chrome plating thickness (20-50 µm), rod hardness (HRC 50-60), material grade (45# or 40Cr), and weight (5-50 kg). These are reference ranges; verify with the manufacturer.
