Sintered Bronze Bushing

This Sintered Bronze Bushing is a precision-machined component engineered for applications requiring stable alignment, low friction, and long service life. With consistent geometry and clean surface quality, it is well-suited for machinery, automation equipment, and assemblies that demand reliable motion and maintenance-free operation.

Each bushing is produced to strict tolerances to ensure stable fitment within mechanical systems:

Height: 0.810 in

Outer Diameter: Ø0.625 in

Inner Diameter: Ø0.450 in

Internal Thread: 3/8-16 UNJF-3B

Runout: Diameters on common axis within 0.010 in

Angular Tolerance: ±0°30′

Edge Break: 0.009 ± 0.006 in

Fillet Radii: 0.0125 ± 0.0075 in

The controlled tolerances help reduce vibration, improve assembly precision, and ensure consistent performance in both rotating and linear applications.

Manufactured from oil-impregnated sintered bronze per:

ASTM B438-73, Grade 1, Type 2

SAE-841 standards

This material provides continuous lubrication through its internal oil network, making it ideal as a Self-Lubricating Bearing in high-cycle or continuous-duty environments.

The part may also be produced from:

Boston Gear SB12 bar or equivalent

Shamban Turcite Type "B" or equivalent for applications requiring ultra-low friction sliding behavior

These options offer flexibility for different mechanical load requirements and wear conditions.

This Machined Bronze Sleeve delivers dependable performance in:

Industrial machinery and automated systems

Gear and linkage assemblies

Actuators, valves, and motion controls

Linear guides and rotating shafts

Equipment requiring quiet, smooth, lubrication-free operation

Its self-lubricating structure reduces shaft wear, lowers friction, and extends service life even in demanding environments.

All parts are deburred and finished with clean edges to ensure safe handling and consistent assembly. Critical features are machined to specification, maintaining dependable performance across production batches.
