🔌 Function

The support bearing locates and carries a rotating shaft, allowing it to turn with minimal friction while holding it in correct alignment under load. Correct bearing condition is essential to maintaining shaft position and preventing vibration within the assembly.

⚠️ Common Signs of Failure

• Rumbling, growling or whining noise that changes with engine or shaft speed
• Detectable radial or axial play in the supported shaft
• Roughness or notchy resistance when the bearing is rotated by hand
• Excessive heat or discolouration at the bearing location
• Metallic particles or bearing debris found in oil or on drain plugs

🛠️ Service Notes

• Approximately 40 mm bore x 90 mm OD x 23 mm width - confirm these dimensions against the housing bore before ordering, since EV-series axles used more than one bearing size across the range
• Supersedes 184113, which itself replaced 181597 - either superseded number may still appear on old paperwork for this same bearing
