connecting rod & bearing bushes

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Connecting rods and bearing bushes are essential components in the operation of internal combustion engines. Here's a detailed introduction to each:

Connecting Rod

1. Function:

• The connecting rod, also known as a conrod, is a critical link between the piston and the crankshaft. Its primary role is to transfer the linear motion of the piston to the rotational motion of the crankshaft, effectively converting reciprocating motion into rotary motion.

2. Parts:

• A connecting rod consists of a small end and a large end. The small end attaches to the wrist pin (also known as a gudgeon pin or piston pin) which can rotate inside the piston. The large end connects to the crankpin via sleeve bearings to reduce friction.

3. Materials:

• Connecting rods are typically made from materials such as mild carbon steel, aluminum alloy, alloy cast iron, graphite cast iron, and alloy steel. These materials are chosen for their strength, durability, and ability to withstand high temperatures and pressures.

4. Lubrication:

• Bearings attached to both ends of the connecting rod are lubricated in two ways: splash lubrication and pressure lubrication. Splash lubrication is used in the big end of the crankshaft, while pressure lubrication is used in the small end bearing.

5. Types:

• Connecting rods can be single piece or two-piece (split piece). Single piece rods have the big end made in one part, while two-piece rods consist of two halves for the big end.

Bearing Bushes

1. Function:

• Bearing bushes, also known as plain bearings or sleeve bearings, are simple cylindrical components used to reduce friction between two moving parts. They consist of a cylindrical inner surface, an outer surface, and a lubrication film between them.

2. Construction and Types:

• There are several types of bearing bushes, including solid sleeve bushings, split sleeve bushings, flanged bushings, and thrust washers. Each type is designed for specific applications and offers unique advantages.

3. Materials:

• Bearing bushes are often made from materials like bronze, brass, steel, or polymer composites. These materials are chosen for their durability and ability to withstand friction and wear.

4. Advantages:

• Bearing bushings offer low friction coefficients, self-lubrication properties, vibration dampening, and are less constrained by space compared to other types of bearings.

5. Applications:

• Bearing bushes find application in a wide range of industries, including automotive (engine components, suspension systems, and steering linkages), industrial machinery (conveyors, pumps, fans, and compressors), appliances (electric motors, power tools, and household appliances), aerospace (landing gear systems, actuators, and control surfaces), and marine (propeller shafts, rudder systems, and winches).

In summary, connecting rods and bearing bushes play crucial roles in the efficient operation of internal combustion engines. Connecting rods transfer the linear motion of the piston to the crankshaft, while bearing bushes reduce friction and wear, ensuring smooth and efficient engine operation.
