Hydraulic Top Link Cylinder 540x80x40 with Quick Release Hook - Code 50881

The heavy-duty hydraulic top link cylinder (Product Code: 50881) 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 compact, reinforced dual-acting architecture with nominal build dimensions of 540x80x40 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 short 170 mm stroke provides exceptional structural compactness alongside high thrust and retraction load parameters, making this link perfectly suited for heavy-duty setups requiring rapid response in constrained working environments.
