Precision Bright Surface SS316 OD 900mm Hot Forged Seamless Bearing Ring

The Precision Bright Surface SS316 Hot-Forged Seamless Bearing Ring, with an outer diameter (OD) of 900 mm, is engineered from premium stainless steel 316. Hot forging delivers superior strength and structural integrity, resulting in a seamless, weld-free construction.
The bright-polished finish improves corrosion resistance and reduces friction, making it ideal for heavy-duty bearing applications in demanding environments. Precision machining ensures tight tolerances and smooth operation. This ring is widely used in aerospace, marine, and industrial machinery sectors, offering a high level of durability, wear resistance, and load-bearing capability that meets stringent industry standards.

Industry News 2026-05-25

What Is Forged Steel? Forged steel is steel that has been shaped by applying compressive force — hammer blows, press tonnage, or die pressure — while the metal is at an elevated temperature, typically between 1,100°C and 1,250°C (2,000°F–2,300°F) for hot forging. The mechanical working breaks up ca...
