Hydraulic Top Link Cylinder 650x60x30 for Fiat - Code 50748

The heavy-duty hydraulic top link cylinder (Product Code: 50748) is a professional-grade hydraulic actuator engineered for precision alignment, real-time geometry adjustment, and secure load retention of three-point linkage implements. Featuring an elongated, reinforced dual-acting architecture with a minimum retracted length of 650 mm and a net weight of 11.17 kg, this mechanism is calibrated to fit the exact requirements of Fiat, OM, and Oro Series utility tractors (including the classic Fiat 640), allowing operators to adjust implement pitch angles dynamically from the cabin.
Design Details and Functionality
This hydraulic top link comes fully equipped with a standard dual-pilot check safety valve threaded to 3/8". The check valve provides a robust mechanical locking force, sealing fluid within the cylinder chambers to maintain the structural rod configuration even under sudden line pressure drops or hydraulic hose ruptures, shielding heavy suspended implements from accidental dropping. The specific hardware layout features a staggered, asymmetrical dual-swivel configuration: a spherical knuckle joint with a 19.3 mm pin bore on the cylinder base side (tractor linkage), paired with a larger 25.4 mm (Category 2) pin bore swiveling ball eye on the rod end side (implement linkage). The combination of a 60 mm cylinder bore diameter, a high-tensile 30 mm micro-polished chrome rod, and a generous 370 mm stroke provides exceptional mechanical reliability along with great long-stroke versatility under tough working field conditions.
