1.2 ID Bronze Bushing Description
1.2 ID Bronze Bushing refers to a bronze bearing with an inner diameter of 1.2 inches, widely used in industrial machinery and mechanical equipment. This bushing is made from high-strength, wear-resistant bronze, offering excellent load-bearing capacity, corrosion resistance, and self-lubricating properties. It provides reliable support and cushioning between shafts and housings, effectively reducing friction, minimizing wear, and extending equipment lifespan. Thanks to its durability and performance under heavy loads or high-speed conditions, the Bronze Bearing is commonly applied in motors, pumps, automotive chassis, construction machinery, and other mechanical systems, making it an essential component for smooth, stable, and long-lasting operation.
Bronze Bushing Function
● Excellent wear resistance: Wear-Resistant Bronze Bushings maintain structural stability and reduce equipment failure in long-term friction environments.
● Strong adaptability: Self-Lubricating Bronze Bushings perform reliably under varying speeds, loads, temperatures, and corrosive conditions.
Customize Bushings According To Scenarios
● Industrial Machinery – Gearboxes, pumps, compressors, and small conveyors.
● Automotive Components – Steering assemblies, drive shafts, and suspension mechanisms.
● Construction & Light Machinery – Excavators, compact loaders, precision lifting equipment.

1.2 mm ID bronze bushing processing Process
Material Preparation: Select suitable bronze material and inspect the blank for quality.
Blank Cutting: Cut the blank slightly longer than the final length and remove burrs.
Annealing (Optional): Heat to relieve internal stress and improve machinability.
Outer Diameter Turning: Rough-turn then finish to the required outer diameter and surface roughness.
Inner Diameter Boring/Drilling: Gradually machine the 1.2 mm ID with precise tolerance and smoothness.
Heat Treatment (If Needed): Apply solution treatment or slight aging to improve wear resistance.
Deburring and Cleaning: Chamfer edges and remove cutting oil and debris.
Surface Treatment (Optional): Apply nickel plating, phosphating, or oil impregnation for corrosion protection and lubrication.
Dimensional Inspection: Check inner/outer diameters, length, and concentricity with measuring tools or CMM.
Final Packaging: Apply thin oil film or plastic packaging and label with specifications and batch number.
