Custom S355J2H Steel Spacer Rings for Heavy Industrial Equipment
MetalKeen manufactures custom S355J2H steel spacer rings for industrial machinery requiring accurate axial positioning, load distribution, and reliable assembly.
Spacer rings are precision-machined components used to maintain controlled spacing between bearings, gears, shafts, rollers, and other rotating or stationary machine elements. Properly manufactured spacer rings improve assembly accuracy, reduce vibration, and help extend the service life of mechanical systems.
Manufactured from S355J2H structural steel, our spacer rings combine excellent weldability, high strength, and outstanding dimensional stability. Every component is produced through CNC turning, milling, drilling, and precision inspection according to customer drawings or OEM specifications.
MetalKeen supplies spacer rings for paper machines, mining equipment, steel mills, gearboxes, conveyors, hydraulic systems, and other heavy industrial equipment, supporting both new equipment manufacturing and replacement parts.
What Is a Spacer Ring?
A spacer ring is a precision-machined circular component installed between machine parts to maintain a specified axial distance, control bearing preload, align rotating components, and distribute loads. Spacer rings are commonly used in bearings, shafts, gearboxes, rollers, and transmission systems where dimensional accuracy is essential.
