Forged Sleeves | Custom Forged Shaft Sleeves
Forged sleeves are critical components used in power transmission and heavy-duty mechanical systems where strength, wear resistance, and dimensional stability are required. Compared with machined-from-bar alternatives, forged sleeves provide improved grain structure, higher load capacity, and longer service life.
At Weforging, every forged sleeve is produced through an integrated manufacturing route combining hot forging, CNC machining, heat treatment, and strict inspection. This ensures reliable performance for OEM machinery and industrial applications.
What Is a Forged Sleeve
A forged sleeve is a cylindrical mechanical component manufactured through forging and precision machining. It is used to support rotating shafts, maintain alignment, reduce wear, and transfer loads within transmission assemblies.
Unlike threaded bushings or pipe fittings, forged sleeves are designed for mechanical transmission systems. The forging process aligns grain flow with the component geometry, improving strength and fatigue resistance.
Forged Sleeve Manufacturing Process
Weforging applies a controlled production process to ensure strength and dimensional stability:
Hot Forging – improves material density and grain flow
Controlled Cooling – reduces internal stress
CNC Machining – ensures precise dimensions and concentricity
Heat Treatment – enhances hardness and wear resistance
Inspection & Quality Control – guarantees OEM-level consistency
This integrated route produces CNC machined forged sleeves suitable for heavy-duty service.
Materials for Forged Sleeves
Material selection greatly affects forged sleeve performance. Weforging offers multiple alloy and carbon steel options:
42CrMo / AISI 4140 – high strength and fatigue resistance
20CrMnTi – suitable for carburized wear surfaces
34CrNiMo6 – excellent toughness for heavy load applications
Carbon Steel (C45 / S45C) – economical choice for general machinery
Heat treatment standards can be customized according to hardness and service requirements.
