Sandusky Limited Polycast Shells
Sandusky Limited Polycast Shells Deliver Superior Performance and Reliability
Over 60,000 Sandusky Polycast Shells have been sold and most are still delivering superior performance. They are commonly used in paper machines for wire turning, felt, reel and winder roll bodies, as well as reel spools. How can this be you ask?
- Inherently round
- Properties are non-directional
- Single piece construction versus multiple pieces welded together
- Available as-cast, rough bored for balance or finish bored
Centrifugal Casting Ensures Our Polycast Shells Maintain Their Shape For Years.
Sandusky Polycast® Shells will maintain their natural shape and balance year after year. Because they are centrifugally cast, Sandusky Polycast shells offer a high degree of uniformity, no weld seam and equal metallurgical properties in all directions. Centrifugal casting using ASTM A27 Gr. N-1 mild carbon steel eliminates concern about residual manufacturing stresses and roll distortions that are indicative of others types of tubing.
Their superior straightness, roundness, and naturally uniform wall thickness greatly facilitates machining, roll finishing, and balancing. Only minimal balance weights are typically needed. In most cases, they require no boring. Most are supplied as-cast, but can be machined by Sandusky Limited to your specifications. With our large custom built machines, we can turn and bore all shells we produce.
