Case Studies

In South Korea, a Forged Steel Manufacturer reported ram leakage and a short seal life in the 3000-ton cylinder. The original stacked v-ring set (7 rings/set) previously used only lasted six months. The short lifespan of the existing seals has caused frequent external leakage, and the large quantity of seals required makes the replacement process cumbersome and time-consuming, ultimately leading to severe productivity losses due to frequent equipment downtime.

Chesterton 11K is a high-performance hydraulic sealing solution featuring an advanced dual-material configuration that significantly reduces friction compared to conventional stack sets. Its exceptional wear resistance drastically extends seal life and prevents premature failure. Additionally, its flexible profile and material ensure a perfect fit even on old, worn rod surfaces, blocking chronic external leakage. This ultimately minimises equipment downtime and substantially boosts operational productivity. By transitioning to the Chesterton 11K, your facility can eliminate frequent external leakage, minimise overhaul costs, and secure long-term reliability for heavy-duty hydraulic presses.

Chesterton 11K Rod Seal.

By replacing a competitor product with our Chesterton seal, we achieved a cost savings of approximately $31,660 for one cylinder of a 3,000-ton hydraulic press after 18 months. Consequently, since each press utilises three cylinders, an annual cost savings of $94,980 was realised per press. Additionally, any extra expenses incurred from holding inventory due to the short lifespan of the previous product were excluded from this evaluation.
