Automotive Connecting Rod Bearings Australia

The piston, connecting rod, and crankshaft are the “living” parts of the engine; those who create the movement by transforming the vertical thrust of the pistons, resulting from the sudden ignition of the fuel mixture in a chamber, into a regular rotary movement transmissible to the transmission components (gearbox, in particular) then to the wheels. Suppose the bearing rod or connecting rod is damaged, it needs to be repaired or changed with the new one. Here at Paylessdeal.com.au, you can find a wide range of Automotive Connecting Rod Bearings in Australia at the best rates.

Price and Availability

The connecting rod is a steel element making it possible to connect one of the engine pistons to the crankshaft, thus imparting a circular movement allowing internal combustion, another form of heat engine. If any of the engine components is damaged, it has to be replaced with the new one. Automotive Connecting Rod Bearings price in Australia ranges from 10 to 100 AUD depending upon the Rod and vehicle type and model. Here, we have enlisted in some of the stores where you can easily purchase any Automotive spare parts at the best prices.

Description

While there are different types of connecting rods, all are made of the same elements: a big end, recognizable by its large hole allowing the crankshaft to be inserted, and a small end, including a smaller hole to connect the piston to it. The whole thing is connected to a metal body, resembling a flat steel rod, which becomes thinner as it approaches the small end. The connecting rods can be of different lengths depending on the piston's rotation to allow the engine to operate. The larger the connecting rod, the longer it will take to rotate.

The connecting rod connects the piston to the crankshaft. Together, they transform linear motion (back and forth of the piston) into rotary motion.

A connecting rod is made up of:

  • ahead connected to the crankshaft,
  • afoot connected to the piston pin,
  • of a body that connects the head and the foot,
  • as well as pads or bearings located in the head and foot to reduce friction and facilitate rotary motion.

Types of connecting rods

Monoblock connecting rods:

The connecting rod is molded in one piece, requires the use of a removable crankshaft.

The assembled connecting rods:

The connecting rod is in two parts, and the head has a "cap" held by screws and/or bolts. An assembled connecting rod allows the use of a single-piece crankshaft and facilitates interventions on moving parts.

Split connecting rods:

A little-known method, the main connecting rod is split at the head's level to allow the second connecting rod to couple to the same crankpin of the crankshaft.

Length of connecting rods:

The length of the connecting rod depends on the piston's stroke (distance it will travel on 1 descent) and the distance between the crankshaft axis and the crankpin where the connecting rod is hooked. An engine with long connecting rods favors torque in practice, while an engine with short connecting rods will favor the rotational speed (power).

The composition, length, and shape of a connecting rod depend on the stresses it will endure. It will undergo traction, compressions, bending, and also thermal stresses: the foot, at the level of the piston, undergoes very high temperatures while the head is lubricated and therefore cooled by the oil bath at the level of the crankshaft.

The connecting rod is built in a very resistant material (even titanium in competition). Most of it has an I-profile and sometimes a ribbing that reinforces the head and the foot.

Stresses of a connecting rod

The difference in size between the head and the foot is mainly due to the friction, which is much more present on the connecting rod/crankpin connection of the crankshaft than at the connecting rod/piston pin.

Connections

Pad or ring:

The most common is the two half-bush methods with an assembled connecting rod for the head and a foot ring.

Connecting rod half bearings

If the connecting rod is in one piece, then a ring must be used for the head and the foot. The materials used must have a low coefficient of friction (reduce friction and facilitate the head's rotational movement on the crankpin of the crankshaft). However, optimum lubrication of the bearings or rings must be ensured.

Roller or needle bearing:

They reduce friction a bit more than bushings and require less lubrication. On the other hand, it can only be mounted on mono block connecting rods, which requires the removable crankshaft. An expensive technique that is no longer mandatory thanks to current manufacturing progress.
