Hydraulic Top Link Cylinder 660x80x40 with Quick Release Hook - Code 50883

The heavy-duty hydraulic top link cylinder (Product Code: 50883) is a professional-grade hydraulic actuator engineered for precision alignment, real-time geometry adjustment, and secure load retention of three-point linkage implements. Featuring a reinforced dual-acting architecture with a minimum retracted length of 660 mm, this mechanism allows tractor operators to adjust implement pitch angles dynamically from the cabin, maximizing working field performance and shifting efficiently into safe road transport configurations.

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, maintaining rod stroke configurations even under sudden hydraulic hose ruptures or line pressure drops, shielding field implements from accidental dropping. The specific hardware layout features a heavy-duty spherical rod eye end with a 25.4 mm pin bore hole on the cylinder base side (tractor linkage), paired with an automatic quick-release catch hook classified under Category 3 National on the rod end side (implement linkage). The combination of a large 80 mm cylinder bore diameter, a high-tensile 40 mm micro-polished chrome rod, and a 290 mm stroke provides excellent mechanical versatility along with high thrust and retraction load parameters, making this link perfectly suited for high-tonnage agricultural implements performing aggressive ground engagement tasks.
