LD-369 Steel Brass Spacer Bushings Sleeves Shafts | Wholesale Supplier

The LD-369 steel and brass spacer bushings collection is a comprehensive range of precision-machined cylindrical components engineered for spacing, alignment, wear reduction, and rotational guidance across mechanical assemblies. The assortment encompasses spacer sleeves, distance bushings, wear bushings, drill bushings, and precision shafts, pins, and dowels, each manufactured from premium materials including carbon steel, stainless steel 304 and 316, brass C3604, bronze, and hardened chrome-plated steel. These components serve as the unsung workhorses of countless industrial, automotive, machinery, and fabrication applications, where they maintain precise dimensional spacing between moving parts, absorb frictional wear, guide drills and shafts, and align mating components with repeatable accuracy. Manufactured under strict ISO 9001 quality controls and dimensioned to DIN and ANSI standards, every bushing and shaft in the LD-369 range delivers the dimensional consistency, surface finish, and material integrity that demanding OEM and MRO environments require.

Material selection is central to the performance of each component in the LD-369 range. Carbon steel bushings and shafts offer excellent strength and machinability for general-purpose spacing and load-bearing applications, while stainless steel 304 and 316 variants provide superior corrosion resistance for food processing, marine, chemical, and outdoor environments where moisture and aggressive media are present. Brass C3604 and bronze bushings are prized for their inherent self-lubricating properties and low friction coefficients, making them ideal for rotating and sliding applications where additional lubrication is impractical or undesirable. Hardened chrome-plated steel shafts deliver exceptional surface hardness and wear resistance for precision linear motion and rotary guidance. Each component is precision-turned to tight h7 and h8 tolerances, ensuring consistent fit and interchangeability across production batches, with outer diameters ranging from 5mm to 50mm, inner diameters from 3mm to 30mm, and lengths from 10mm to 100mm for bushings, plus shaft diameters from 8mm to 30mm with lengths extending to 300mm.

The LD-369 range is offered in a variety of surface finishes to suit different functional and aesthetic requirements. Silver steel provides a clean, natural machined appearance for general industrial use, while brass gold offers a distinctive, corrosion-resistant finish favored in electrical and decorative applications. Black oxide coating enhances corrosion resistance and reduces light glare in machinery assemblies, and chrome-plated silver delivers a hard, low-friction, mirror-smooth surface for precision motion applications. These finish options, combined with the extensive material and dimensional range, make the LD-369 collection suitable for an exceptionally broad spectrum of use cases, from automotive engine and transmission spacing to machinery guide bushings, jig and fixture drill bushings, furniture and hardware alignment pins, electrical insulator spacing, and hydraulic and pneumatic cylinder componentry. The precision dowels and pins provide positive location and shear resistance in assembled structures, ensuring components remain accurately aligned under load.

For wholesale buyers, hardware distributors, and OEM manufacturers, the LD-369 collection represents a high-value, versatile sourcing solution backed by competitive factory-direct pricing and flexible customization. Mixed orders across materials, sizes, and finishes are supported, allowing buyers to consolidate their bushing and shaft sourcing through a single reliable supplier. Customization options include non-standard dimensions, special material specifications, tailored surface treatments, and private-label packaging. Each order is packaged in bulk plastic bags or oil-coated wrapping to preserve surface integrity during transit and storage, with 500 to 2,000 pieces per carton accommodating both large-scale production runs and smaller inventory replenishment. With a minimum order quantity of 1,000 pieces and a production lead time of 10 to 20 days, the LD-369 steel and brass spacer bushings, sleeves, and precision shafts deliver the quality, consistency, and supply reliability that professional buyers demand.
