Spherical Washers

Seastrom Manufacturing is a premier domestic spherical washer manufacturer serving the aerospace, mining and industrial sectors. Our high-precision spherical washers, also known as self-aligning washers or leveling sets, function as a heavy-duty ball-and-socket joint, pairing a convex top with a concave bottom. This design automatically compensates for angular deviation up to 4 degrees, ensuring a solid grip on non-parallel surfaces, such as rough castings or forgings, where standard washers would cause dangerous bolt bending and fatigue.

Standard and Custom Capabilities

We offer a comprehensive range of standard DIN 6319 compatible sets, including Type C (convex) and Type D (concave). We also specialize in custom spherical washers, allowing engineers to specify unique materials like stainless steel (303 or 316) for corrosion resistance or case-hardened steel for high-load applications. From prototypes to full-scale runs, we machine to your exact specifications to meet your project's unique tolerances.

Supply Chain Stability

Procurement managers trust Seastrom for made in the USA quality, full traceability and reliable inventory. Whether you are looking to buy spherical washers for immediate maintenance repairs or require a certified wholesale spherical washers partner, we provide the scalable manufacturing infrastructure to support your supply chain without the long lead times associated with imports.
