About

What Is a Mill Duty Cylinder?

Mill duty cylinders are a durable, reliable product to reduce downtime and maintenance costs across industries. Their design specifications are not subject to NFPA limitations, meaning hydraulic mill cylinders have heavy-duty construction and are designed with bigger pistons, steel-flanged end caps, heavy-wall steel tubing, an advanced gland design, and other appealing features. Its high-pressure rating is above the industry standard and mill duty cylinders are known to be incredibly reliable in even the most intense environmental and operational conditions. They come as both hydraulic and pneumatic mill duty cylinders. 

Why Do Mill Duty Cylinders Fail?

Unfortunately, mill duty cylinders aren’t immune to damage or failure. If they fail, it is usually due to physical damage or the deterioration of their seals. If the cylinder encounters physical damage, it is usually from an external source such as another machine or an object that falls and hits the cylinder. This physical damage could result in a rod that bends or a barrel that dents which will prevent the cylinder from stroking fully. It’s also possible for physical damage to impact the rod threads which will break the cylinder away from the rod mount. Excessive wear can also cause physical damage to mill duty cylinders. In the case that the rod end doesn’t move parallel to the barrel, it can cause damage to the barrel, rod, piston, and bearing.
