Product Overview:
We know how frustrating and expensive downtime caused by a faulty, prematurely worn or underperforming hydraulic cylinder can be. This is why we developed a purpose-built hydraulic cylinder loaded with features specifically suited to hydraulic thumb applications.
Premium Sealing System – Every Viking West hydraulic thumb cylinder is fitted with a premium sealing system proven to prevent system contamination and withstand the pressure spikes and side loading associated with hydraulic thumb applications.
Induction Hardened Chrome Plated Rod – Each thumb cylinder rod is induction hardened and chrome plated to provide the highest level of scratch, dent and corrosion resistance.
Spherical bearings – Rod eyes are fitted with replaceable heavy-duty spherical bearings to ensure axial forces are efficiently transferred without binding that causes premature wear and eventual sloppiness at the pin connection.
Heavy Gauge Steel Guard – Transfer pipe is protected from unintended impacts by a heavy gauge steel guard.
O-Ring Boss Ports – Cylinder ports are O-Ring Boss (ORB) type to ensure reliable leak free performance in high vibration applications.
100% Leak Test – Every cylinder we supply has been bench tested to ensure they are functioning properly and leak free, so they are ready to go to work when you are.
Peace of Mind - Every Viking West thumb cylinder comes with an industry-leading 24-month warranty. If you need our support, we promise to have service parts in stock and qualified technicians available to get you back up and running.
