Limited-Slip Differential

A limited-slip differential is a common type of differential that limits the maximum amount of rotation of its two input shafts while allowing both shafts to move at the same rate. This type of differential is often used in industries such as power production, oil and gas, chemical plants, and the transportation industry. Because limited-slip differential products have certain advantages, they are becoming more popular and are becoming more commonplace in some types of industry. This article will explain limited-slip differential advantages and disadvantages and what to look for when choosing a limited-slip differential. The article also gives you an understanding of limited-slip differential technologies.

Differential Types

There are four different types of limited slip differential in general: reciprocating, screw-driven, gravity-driven, and alternating. Most limited-slip diffs are made from materials with limited-slip travel. As an example, the slip rating of a slip-resistance bearing in general motors is one hundred thousandths of an inch. The limited-slip differential is generally much less than this, as most power outputs in a power steering system are on the lower side of one hundred thousandths of an inch.

Reciprocating limited-slip differential applications typically use crutches. In a reciprocating application, there are clutch discs that lock the axle into a specific position. A limited-slip differential does not use clutches and instead uses a limited-slip roller. However, limited-slip rollers usually have clutch discs that can be manually released without activating the motor. Therefore, this application uses fewer clutches and thus can be used more economically.

Another type of limited-slip differential is a screw-drive limited-slip differential. A screw drive differs from a reciprocating differential because it is powered by the vehicle’s traction force. A screw drive also has a limited-slip rating but is limited to applications where high rolling speeds are desired. This type of differential uses a series of jackscrews that act as rollers. These jackscrews are located at the end of the driveshaft and limit both the linearity and the width of the shaft.

Next, we have the one wheel and two-wheel open diffs, which differ because they are self-contained. One wheel on one side is supported by a drum, whereas the other is supported by a drum with a pinion that is directly attached to the wheel. These types of diffs are used for limited-slip differential applications, but they do not provide the torque necessary for applying maximum traction. In general, one wheel and two-wheel open diff are only suitable for flat or level grounds and is therefore not widely used.

The final variety is a limited-slip differential called an SDAD or limited-slip differential. SDADs can be either open or limited. The function of an SDAD is to control the output shaft speeds, which is usually controlled by an output shaft seal. These types of diffs are often used with an automatic transmission system and can sometimes be seen in off-road trucks.


There are several different reasons why vehicles may need a limited-slip differential. If the vehicle is to be used in wet or muddy conditions, this will make an open differential or limited-slip differential unnecessary. Another reason why these types of diffs are important is to allow adequate traction in some areas where pavement is not smooth, such as in the case of dunes or rice fields. In addition, the presence of snow and ice can create problems if the tires have insufficient traction. Lastly, the presence of water and oil can sometimes damage the interior of the car, so it is best to avoid these conditions when possible. In these cases, the limited-slip differential is necessary to protect the integrity of the vehicle.

A limited-slip differential is not necessary to drive a truck in all cases. Trucks can function with a standard, open diff. In many cases, however, the limited-slip differential is an important component of the truck. If the truck must go through hazardous road conditions, a limited-slip differential is a necessary component to ensure safety.
