💡 Why are hardened steel thrust washers used in axial bearing assemblies instead of standard flat washers?
It’s all about load control and surface durability:

• Precision ground faces improve load distribution

• Hardened surface resists brinelling under axial force

• Maintains flatness under compressive stress

• Supports needle roller thrust bearings for smooth rotation

If you need a clean, thin axial load surface that holds up under pressure, this AS5578 washer gets the job done right.
