Product Parameter

Effect:

It belongs to a type of engine sliding bearing, and it mainly has the function of supporting the crankshaft axially inside the engine. In order to ensure that the crankshaft is prevented from direct friction with the body while the crankshaft is turning, it is also to prevent the axial movement of the crankshaft.

Usual problems of trust bearings

1. The size is too large, the clearance between the alloy surface and the shaft end is small, friction occurs, and the thrust plate is damaged in advance, resulting in damage to the crankshaft connecting rod, bearing bush and cylinder block.

2. The size is too small, the clearance is too large, and the axial movement of the crankshaft is large, causing the engine to have noise and insufficient horsepower.

3. The flatness is out of tolerance, local contact, and no lubricating oil film, causing the crankshaft connecting rod bearing bush to be scrapped and causing the cylinder block to wear.

4. The roughness is poor, the local area of the alloy surface is in point or line contact, and the gap is small. Cause the crankshaft connecting rod bearing bush to be scrapped, resulting in the wear of the cylinder block.

5. Poor cleanliness, dirt and burrs flow into the cylinder block, causing the connecting rod bearing bush to be scrapped, and the cylinder block may be worn.
