🔌 Function

The roller bearing supports and locates a rotating shaft, allowing it to turn with minimal friction while carrying radial load. Correct bearing condition maintains shaft alignment and smooth power transmission through the assembly.

⚠️ Common Signs of Failure

• Growling, rumbling or grinding noise that changes with shaft speed
• Excessive shaft play, roughness or notchiness when turned by hand
• Vibration through the drive or engine that increases under load
• Metallic particles or bearing debris found in the oil or on the magnetic drain plug
• Localised overheating or discoloration around the bearing housing

🛠️ Service Notes

• Keep the bearing in its wrapper until the moment of fitting and work with clean hands and clean tools — a roller bearing is ruined by grit long before it is ruined by use
• Apply the fitting force only to the race being fitted, using a tube or drift that bears squarely on the whole ring face, so the load never passes through the rollers; never strike the bearing or press on the loose race
• Warming the inner race evenly in oil or a purpose-made bearing heater lets an interference fit slide on without hammering — never heat a bearing with a flame, and stay within the temperature the manufacturer's instructions allow
• Check the shaft and housing seats for wear, scoring and burrs first; a slack or damaged seat will destroy a new bearing quickly
• Lubricate with the grade specified for that position, and where the bearing takes an adjustable preload or endfloat — tapered roller bearings especially — set it by the workshop manual procedure rather than by feel
