Parameter	Value	Tolerance	Industry Standard Notation
Inner Diameter (ID)	160.00 mm (6.300 in)	+0.00 / -0.10 mm	160 mm
Outer Diameter (OD)	190.00 mm (7.480 in)	+0.05 / -0.00 mm	190 mm
Width (Thickness)	28.60 mm (1.126 in)	±0.15 mm	28.6 mm
Spindle Shoulder O.D.	121.10 mm (4.767 in)	±0.05 mm	Mounting reference only

✅ Key Clarification:

"121x160x26/30mm" is a MISLEADING notation – 121mm = spindle shoulder (not seal OD).
Correct dimensional notation: 190x160x28.6 mm (ODxIDxWidth).

A. Axle Weight Classes

Axle Rating	Application	Exclusion Warning
38,000 lbs	✔️ Volvo FM/FH Series (I-Shift Axles) ✔️ Yutong ZK6600/ZK6800 Series Buses ✔️ Sinotruk HOWO TH7, Shacman X3000	❌ NOT for 46,000 lbs axles (use 393-0174)
46,000 lbs	❌ NOT APPLICABLE – Requires larger seal (393-0174)	Using 393-0173 causes immediate failure

B. Verified Vehicle Compatibility

Manufacturer	Valid Models	Invalid Models
Yutong	ZK6600H, ZK6700H, ZK6800H (Rear Drive Axles)	ZK6551 (uses 393-0168)
Volvo	FM12, FH12, FM13, FH13 (10.5-tonne I-Shift Axles)	All steer axles
Other	FAW J6M, Sinotruk C7H, Shacman X5000 (38,000-lb rear axles only)	Light-duty trucks (e.g., <15t)

Feature	Technical Rationale
Triple-Lip Design	- Outer lip: Exclusion of contaminants - Middle lip: Lubricant retention reservoir - Inner lip: Primary seal (spring-loaded)
Heat Dissipation	Dual-wall steel case transfers heat from lip to hub (reduces thermal degradation)
Anti-Rotation Security	Knurled outer diameter + interference fit prevents spin-in-hub (critical at >100 km/h)
Bearing Protection	Ventilated anti-corrosion shield directs lubricant to bearing contact surfaces
