Hydraulic Parts and Castings — OEM Components to Customer Drawing and Specification

SMI manufactures hydraulic parts and castings to customer drawing and technical specification — covering hydraulic fittings, cylinder end components, mounting brackets, flanged connectors and associated precision machined components. Production spans casting, precision machining and surface treatment, with finished components supplied to hydraulic equipment manufacturers and industrial OEM customers worldwide.

Every component is produced to the customer’s own engineering drawing or specification — including material grade, dimensional tolerances, pressure rating, surface finish and inspection requirements. SMI does not supply standard catalogue hydraulic components — our capability is in manufacturing OEM parts to the exact requirements of each customer’s hydraulic system design.

Components Manufactured

Hydraulic Fittings and Connectors

Cast and precision machined hydraulic fittings — including flanged tube connectors, port adaptors and inline fittings — manufactured to SAE, ISO or customer-specified port standards. Bore dimensions, thread forms and sealing face geometry machined to the tolerances required for reliable high-pressure sealing in service. Materials typically include ductile iron, carbon steel and stainless steel depending on pressure rating and fluid compatibility requirements.

Cylinder End Components

Hydraulic cylinder end caps, gland housings, clevis ends and trunnion mounts — cast and machined components for hydraulic cylinder assemblies used in industrial machinery, mobile equipment and offshore applications. Bore concentricity, seal groove geometry and thread dimensions are machined to the tolerances specified in the customer’s cylinder design drawing.

Mounting Brackets and Clevises

Cast steel mounting brackets, clevis forks and rod end attachments for hydraulic cylinder and actuator installations. Bore dimensions, pin hole alignment and mounting face geometry machined to assembly drawing requirements. Single-eye, double-eye and clevis fork configurations available to customer drawing.

Flanged Base Components

Square and round flanged base castings for hydraulic valve mounting, pump mounting and manifold attachment — machined bolt patterns, precision bores and flat mating faces to customer specification.
