Fersa Wheel End Catalog – WHU (2021)

Overview
The WHU (Wheel Hub Unit) catalog compiles dimensional data, exploded views, and service notes for integrated hub units and matched taper sets used on commercial vehicles.

Coverage & contents

• Dimensional tables for hub units and bearing modules.
• Exploded views & kit composition to ensure all parts are available at install time.
• Torque & preload guidance to secure reliable service life.
• Cross‑references to speed up identification from legacy part numbers.

Selection criteria

• Match by hub family and dimensions; verify ABS ring type and sealing.
• Consider load spectrum and operating temperature for grease selection.
• Check flange geometry and fastener class for compatibility.

Application notes

• Follow torque sequences; avoid impact tools on precision fasteners.
• Measure end‑play; re‑check after initial road test.
• Protect sealing lips and magnetic encoder surfaces during handling.

Reliability & quality

• Process control and bench validation aligned with vehicle manufacturer specs.
• Traceable labeling and robust packaging for distribution.
