The Benefits of Using Self-Lubricating Bushings for Your Next Pivot

Like any other auto part, control arm bushings wear out over time. This results in an increase in irritating vibrations that can be dangerous in severe cases. The bushings in the control arms also wear out due to the stress that extreme driving conditions put on the control arms. Additionally, environmental factors and oversized tires tend to transmit more vibration through the bushing than conventionally sized tires. Whatever the cause, bushings can be the source of many problems.

wear and cracking

The main cause of dry valve side bushing cracking is a mismatch in thermal expansion of the core and flange. This situation can seriously compromise the safety of the power system. To improve the safety of dry valve side bushings, the crack development of epoxy impregnated paper under various conditions was investigated. A coupled thermomechanical simulation model was also used to study the cracking process.
The first step in diagnosing the cause of bushing wear and cracking is a visual inspection. The bushing of the lower control arm is fixed to the frame by a bracket. If there are any visible cracks, it’s time to replace the bushing. However, there is no need to replace the entire suspension. In some cases, worn bushings can cause a variety of problems, including body lean, excessive tire wear and cornering noise.

Maintenance free

If you’re considering maintenance-free bushings for your next pivot, you’ll be wondering what to look for in these components. The bushing protects the housing from corrosion and keeps the bushing under pressure. However, many users are not familiar with what these components can do for their applications. In this article, we’ll look at several examples of truly maintenance-free pivots and discuss their requirements.
One of the most popular types of maintenance-free bushings are flanged and parallel. Unlike worm gear bushings, these self-lubricating metal bearings are ideal for a variety of applications and conditions. They reduce failure and downtime costs while providing the long-term lubrication required by other types of bushings. Since these sleeves are made of lead-free material, they are RoHS compliant, which means they are environmentally friendly.Another common maintenance-free bushing is plastic. This material is easier to find off-the-shelf and relatively inexpensive to produce. However, it is not suitable for high load applications as it will crack under heavy loads and damage mating parts. Plastics can also deviate if the manufacturing process is imprecise. Plastic bushings can also crack when subjected to high loads.


When using a self-lubricating bushing, there is no need to apply grease to the bushing. Oily liquids tend to attract dirt and grit, which can wear away the graphite prematurely. By eliminating the need for regular lubrication, you will reduce equipment maintenance costs. This article will explore the benefits of self-lubricating bushings. You will love your kindness.
Self-lubricating bushings have a strong base material to withstand radial bearing pressure while providing shaft support at the contact surfaces. The material also has good fatigue properties and low friction motion. Self-lubricating bushings can be used in environments with high temperatures and aggressive media. These products can also withstand enormous pressure. When using self-lubricating bushings, it is important to select the correct material.
The main advantage of using self-lubricating bushings is ease of maintenance. They don’t require oil to run and are cheaper to buy. Their main benefit is that they can significantly reduce your machine running costs. These bearings do not require oiling operations, reducing maintenance costs. These bearings also offer a simplified mechanical design due to their thin walls and high load capacity. In addition, they reduce noise levels while maintaining excellent wear resistance. Plus, their materials are ROHS compliant, which means they don’t require oil.
Hydropower installations are another area where self-lubricating bushings have proven their advantages. They reduce maintenance costs, extend equipment life, and improve environmental benefits. For example, the Newfoundland Power Company uses self-lubricating bushings in the gates of its hydroelectric power plants. These self-lubricating bushings eliminate grease from entering waterways and tailraces. As a result, power companies are able to reduce maintenance and costs.

compared to cartilage in the human body

What is the difference between tendon, bone and cartilage? Human cartilage is composed of collagen and elastic fibers. In contrast, fibrocartilage contains more collagen than hyaline cartilage. Both cartilage types are composed of proteoglycans, which have a protein backbone and glycosaminoglycan side chains. These components work together to provide structure and flexibility to the cartilage.
Bone is a combination of living and dead cells embedded in a matrix. The outer hard layer of bone is dense bone, and the inner layer is spongy, containing bone marrow, blood vessels, nerves, etc. Bone contains both organic and inorganic substances, and this process of hardening of the matrix produces bone. On the other hand, cartilage consists of chondrocytes and a matrix composed of collagen and elastin fibers. Compared to bone, cartilage is yellow and contains elastic fibers.
Although bone and cartilage are structurally identical, cartilage is more flexible. It is mainly found in the joints and respiratory system and requires flexibility. Its ingredients include collagen and proteoglycans, which provide compression and abrasion resistance. Furthermore, connective tissue is composed of cells, fibers and matrix.
The basic substance of cartilage is chondroitin sulfate, which is derived from animals. Although cartilage grows more slowly than bone, its microstructure is less organized. There is a fibrous sheath covering the cartilage, called the perichondrium. The molecular composition of the ECM plays an important role in the function of cartilage. The collagen matrix is ​​important for cartilage remodeling and consists of changes in the collagen matrix.

Compared to metal-on-bone contact

Both metal-on-bone contact are known to cause a significant increase in the pressures in a joint. To compare the two, we first calculated the joint contact pressures in each model and compared them. The results of this study support previous research on this subject. The following sections discuss the benefits of both types of contact. They also outline some key differences between the two.
