Product Description

Cummins QST30C Main and Rod Bearings High Speed 0.01mm Tolerance Diesel engine bearing

Product Description:

Excavator diesel engine bearings, also known as diesel engine bearings, are an essential part in the operation of a diesel engine. These bearings support the crankshaft, responsible for converting the reciproCaterering motion of the pistons into rotary motion, and reduce the friction between the crankshaft and the engine block, which is necessary for the efficient operation of the engine and used for driving the mechanical parts of the engine.

These bearings are highly important and have to be strong enough to withstand vibration produced by the diesel engine. It is essential to ensure that the parts are properly sized, machined and fit snugly together. This ensures that the seals fit correctly and reduce the risk of excessive wear.



Excavator diesel engine bearings possess many important characteristics that ensure reliable operation and long-term use. First, they need to be strong and wear-resistant, constructed of high-strength materials such as special alloy steel or aluminum alloy. Additionally, the bushing material of excavator diesel engine bearings needs to have a low coefficient of friction, such as Babbitt alloy or special coating. This helps reduce frictional losses and heat generation, thus improving engine efficiency and performance.

Meanwhile, excavator diesel engine bearings also need to provide excellent shock absorption and vibration absorption performance. This can help reduce vibration transmission to other parts of the engine, reducing noise and vibration levels. In addition, bearing design should take good lubriCatererion performance into consideration to ensure sufficient lubriCatererion between the crankshaft and the bearing, reducing friction and wear while in operation. Finally, the bearings should match the size and geometry of the crankshaft sun and engine block to ensure good contact and support.

Overall, excavator diesel engine bearings possess many important characteristics to ensure reliable operation and long-term use under harsh working environments.

Diesel engine bearings are used in a wide range of diesel engines, from excavators, trucks, and generator sets to ships, agricultural and construction machinery, as well as industrial equipment and heavy machinery. From these different engines, they offer a variety of benefits, such as:

Diesel generator set: diesel engine bearings can support the crankshaft, ensuring a stable operation and output power.

Excavators and loaders: bearings help drive sticks, tracks and other moving parts for digging, loading and earthmoving.

Trucks and Commercial Vehicles: diesel engine bearings provide a vital support and friction-reducing role - which is essential for the engine's performance and longevity.

Ship engine: bearings support the crankshaft, converting piston motion into rotational power to drive the ship forward.

Agricultural machinery: bearings enable the engine function and agricultural operations.

Industrial Equipment and Heavy Machinery: bearings provide support and reduce friction between the engine and mechanicals parts.

Diesel engine bearings serve as a necessary component in many industries, guaranteeing optimum engine performance as well as effective operations.

Packing and Shipping:

Diesel Engine Bearing Packaging and Shipping:

Diesel engine bearings are typically packaged in individual boxes or bags and placed in a larger shipping carton. Each box or bag should be securely packaged to prevent damage during transit. The shipping carton should be clearly labeled with the product name, weight, and destination address. The carton should also be sealed with strong packing tape to ensure the integrity of the contents.
