🔌 Function

The roller bearing supports a rotating shaft or gear, carrying radial load while allowing it to turn with minimal friction. Correct bearing condition is essential to maintaining shaft alignment and smooth power transfer through the drive or transmission.

⚠️ Common Signs of Failure

• Growling, rumbling or whining noise that changes with shaft speed
• Excessive shaft play, roughness or notchiness when turned by hand
• Metallic particles or bearing debris found in the oil or on the magnetic drain plug
• Overheating or discoloured races and rollers from loss of lubrication
• Vibration under load together with gear or seal wear caused by shaft misalignment

🛠️ 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
