Online ServiceCrush provides the bearing shell fits tightly in the bore, eliminates movement which would wear the bearing bore in the housing as well as the back of the bearing, facilitates proper lubrication and heat transfer.Watch out for reduced or even no crush in old machines or after a wreck.
Chat OnlineBearing crush is measured in a fixture with the same dimensions as the bore the bearing is intended to be used in.The fixture is essentially like a bearing cap with the exception that one side of the cap has a stop at the parting line where the bearing parting.
More DetailsBearing crush, as it is called, is incorporated for a number of reasons, for when clamped together the compression in the bearing shells provides a high resistance to the shell turning or progressively creeping in the direction of the crankshaft, as well as supporting.

More DetailsExcessive bearing crush promotes a similar effect if the bearing housing bore is carelessly machined or the bearing cap is over-torqued.According to clevite, excessive crush condition results in a wear pattern across more than three-quarters of the bearing.

More DetailsBearing crush each half bearing is made slightly higher than exact half of the housing bore diameter.When these bearings are installed in a housing bore and the caps tightened, the parting faces mate with each other.The bearing crush creates a radial pressure and ensures proper seating of the bearing to the wall of the housing.
More DetailsSplit bearing is made for sustain radial pressure when shaft rotating in the bearing.Normal half bearing is smaller than split bearing.The split bearings crush height sets up radial pressure on the bearing halves so that they are forced tightly into the housing bore.For a soil, given d10 0.

More DetailsSpread most connecting rod and main bearings are made with spread.This means that the distance across the parting faces of the bearing insert is slightly greater than the actual diameter of the housing bore.Spread may vary in the range of 0.005-inch to 0.030-inch.Spread enables a positive fitting of the bearing against the total housing bore.

More DetailsThe major type of engine bearing failure is material fatigue.It is caused by running the bearing at load above the fatigue limit.If load acting to the bearing is higher than the fatigue strength of the material, fatigue cracks form on the bearing surface, spread towards the back layer and may result in peeling off the bearing material.

More DetailsBearing crush will usually keep the bearing from spinning during meltdown of the aluminum while the engine is operating.However, as adhesive wear progresses into the steel back, the force of seizure will become greater than the crush force and the bearing will stick to the crankshaft and spin in the bore.
More DetailsCrush fit has to be more or less exact because too much crush fit may deform the bearing to such an extent that it rubs against its journal.Insufficient crush fit means the bearing will not be held firmly in place and may move back and forth within its housing, increasing the risk of it spinning or seizing.
