KRP3122 IEP Main Bearing Kit

Description

Description

In a piston engine the main bearings are the bearings on which the crankshaft rotates usually plain or journal bearings. The bearings hold the crankshaft in place inside the engine and prevent the forces created by the piston and transmitted to the crankshaft by the connecting rods from dislodging the crankshaft. They instead force the crankshaft to convert the reciprocating movement into rotation. Most engines have at least two main bearings, one at either side of the crankshaft and may even have as many as one more than the number of the crankshaft pins. Increasing the number of the bearings will generally increase the size and cost of the engine but it will also provide more stability to the crankshaft.

Functions of the KRP3112 IEP Main Bearing Kit

The bearing is a device supporting a mechanical element and providing its movement relatively to another element with minimum power loss. The rotating parts of the internal combustion engine are equipped with sleeve type sliding bearings. Their main function is to allow for free movement during the engine cycles. The reciprocating engine is characterised by cycle loading of the bearings. The load is a result of alternating pressure of combustion gases in the cylinders. Only sliding bearings have the strength to provide an even distribution of the applied load over a relatively wide area. The main bearings support the crankshaft providing its rotation under inertia forces generated by the parts of the shaft and oscillating forces transmitted by the connecting rods.

Benefits of using the KRP3122 IEP Main Bearing Kit

The main bearing kit has been designed to work seamlessly with the make and model of engine specified. The manufacturer has chosen the material that best performs under the extreme pressure and stresses the bearing must cope with on a daily basis. The main bearing consists of two halves, an upper and lower. The upper part of the main bearing generally has an oil groove on the inner surface to allow for constant lubrication.
