Hydraulic Top Link Cylinder 600x70x35 with Dual Ball Joints - Code 50617
The heavy-duty hydraulic top link cylinder (Product Code: 50617) is a professional-grade hydraulic actuator engineered for structural coupling, real-time geometry adjustment, and secure load retention of heavy three-point linkage implements. Featuring a reinforced, oversized barrel configuration (minimum retracted length of 600 mm and a net weight of 12.17 kg) tailored to match the technical specifications of standard utility, field, and crawler tractors from Same, Lamborghini, Landini, Hürlimann, and Claas/Renault, this dual-acting mechanism allows 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 field implements from accidental dropping. The hardware layout features a symmetrical Category 2 configuration, with standard spherical knuckle joint swiveling ball eyes on both the cylinder base side (tractor linkage) and the rod end side (implement linkage), each machined with a 25.4 mm pin bore hole. The combination of an oversized 70 mm cylinder bore diameter, a high-tensile 35 mm micro-polished chrome rod, and a generous 300 mm stroke provides massive mechanical pushing force along with great long-stroke versatility under tough working open-field or crawler conditions.
