This product is a precision cast steel ring specifically engineered for heavy-duty machinery and transmission systems. The outer rolling track undergoes advanced induction hardening, achieving a surface hardness of 50-54 HRC with an effective case depth of 1.5-3.0 mm, which significantly enhances wear and contact fatigue resistance. All machining dimensions are precisely CNC-machined with proper casting allowances. This highly durable component is ideal for demanding applications such as slewing bearings in wind turbines, heavy construction machinery, and mining equipment.
