Engine Bearings

The main bearings are located in the engine block where the crankshaft is situated. 1 shell is located in the engine block and the other is in the crank cap. Main bearings may have certain characteristics such as oil holes, locating tags and oil grooves.

Thrust Washers

Thrust washers are either separate from the main bearing or integrated into one or two of the main shells. The thrust washer is designed to govern the lateral movement of the crankshaft. This is called the "end float". Oversize thrust washers are available for some engines so the end float can be re-calculated if there is excessive wear.

Cam Bearings / Bushes

The bearings sit between the cylinder head casting and the camshaft caps which house the camshaft. These bearings may have oil holes for certain engines to help keep the camshaft lubricated.

Conrod / Big End

These shells are located at the larger end of the connecting rod. These shells may have certain characteristics such as oil holes & locating tags. The conrod bearings are made of different composite metals such as Silicon Aluminium, Lead Copper, Copper Silicone Silver. Our range of race series bearings have a range of coatings or additional overlays to increase hardness & load capacity. We keep oversized bearings for crankshafts that have been machined or "ground" to an undersize.

Small End Bushes

These bearings are located at the smaller end of the connecting rod. This is where the gudgeon pin of the piston is located. We can source these bearings if your conrod requires them. Often these bearings come with the conrod. Small end bushes either come at a specific size or need to be lined bored to achieve the correct fitment.
