Bearings support smooth running

The bearings in your engine are relatively small but they play a vital role in keeping everything running smoothly. Worn bearings will seriously affect the operation of your engine, leading to over-heating, excessive noise and wear on other components and, in extreme cases, to the failure of the engine unit itself.


To prevent this, you need to follow the relevant maintenance instructions and, when necessary, replace bearings before they become an issue.

Your engine’s bearings protect the crankshaft and engine itself from damage, as well as keeping the engine lubricated.

Bearings are found in many of the machines we use every day. Without bearings, we would be constantly replacing parts that wear out from friction, so it is important to check them in accordance with the schedules supplied when you bought your engine.

Perkins bearings are either tangless or tanged, as dictated by the engine model and unit you are using. The tang – sometimes called a lug – helps to position the bearing shell laterally in the housing. The location tang does not prevent the bearing from turning inside the housing.

High quality materials

Bearings are made of high quality materials, typically either aluminium, alloy or tin. The actual choice of material will depend on what is the best option for that engine model. In this way, the material is best matched to the load levels of the engine over a prolonged period.

Although a small part of the engine, bearings have many important functions. They include:

  • Supporting the rotating components of the engine, including the crankshaft
  • Directing oil flow around the engine
  • Controlling excess noise

Additional noise from the engine can often be a warning sign that the bearings are wearing out but with proper maintenance, this issue should not arise.
