Half Bushing Self Lubricating Bearings – High Performance,
Bearings are a fundamental part of mechanical systems, playing a crucial role in reducing friction between moving parts. The design, shape, and geometry of a bearing are critical factors that determine its suitability for specific applications. Among the various types of bearings, the half-shell bearing bushing is particularly interesting due to its versatility and efficiency.
Half-Shell Bearing Bushing: An Overview
The half-shell bearing bushing, also known as a split bearing bushing, is a type of plain bearing that is commonly used to accommodate radial loads. Unlike full bearings, half-shell bearings are split into two pieces, which allows for easier installation and maintenance. This design is particularly beneficial in situations where the bearing is not accessible from the end of the shaft.
The two halves of a half-shell bearing can be held in place by a housing or a clamp. When closed around the shaft, they provide a continuous surface that supports the shaft, reduces vibration,

Half Bushing Graphite Plugged: A Solution for High-Temperature and Corrosive Environments
In industries that require high-temperature and corrosive environments, finding the right material for components such as bushings can be a challenge. Fortunately, half bushing graphite plugged is a solution that has proven to be effective in such environments.
Half bushing graphite plugged is a type of bushing made from graphite and is designed to withstand high temperatures and corrosive environments. The bushing is composed of two parts, the first being a metal sleeve that is coated with a layer of graphite, and the second being a graphite plug that fits into the sleeve.
The metal sleeve provides structural support and serves as the primary interface with the mating surface, while the graphite layer on the sleeve provides a low-friction surface for the graphite plug to slide against. The graphite plug is made from a high-purity graphite material that has excellent thermal and chemical resistance, making it an ideal material for use in high-temperature and corrosive environments.
The combination of the metal sleeve and the graphite plug provides several benefits over traditional bushing materials such as bronze or plastic. Firstly, the graphite plug’s low coefficient of friction provides excellent wear resistance, reducing the need for frequent maintenance and replacement. Secondly, the graphite plug’s high thermal conductivity helps to dissipate heat, which is essential in high-temperature environments. Finally, the graphite material’s chemical resistance ensures that the bushing will not corrode, making it ideal for use in harsh chemical environments.
Half Bushing Graphite Plugged is an effective solution for industries that require high-temperature and corrosive environments. Its unique composition of a metal sleeve coated with a layer of graphite and a high-purity graphite plug provides excellent wear resistance, thermal conductivity, and chemical resistance, making it an ideal choice for bushing applications in such environments.

Sliding Bearing
Sliding shaft shim is the part of sliding bearing and shaft contact, very smooth, generally made of bronze, friction-reducing alloy, and other wear-resistant materials, in special cases, can be made of composite materials, plastic or bimetallic bearings. Also called “bushing”, the shape of the tile-shaped semi-cylindrical surface.

The bushings can be made of different materials such as Hastelloy bushings, fluoroplastic bushings, tin-based bushings, lead-based bushings, and copper-based bushings.
1.1. No oil supply device, oil injection hole, oil groove processing
The cost of oil supply unit, processing cost, assembly cost, and other redundant costs and time savings, can greatly reduce the manufacturing cost.
2. Reduction of operating costs
Significantly reduce the use of lubricating oil and equipment maintenance costs, and also eliminate the risk caused by insufficient oil supply.
3. Reduction in design time
Oil-free can greatly simplify the design and structure, reduce the cost and save the design time. In addition, the use of self-lubricating bearings can also improve the mechanical properties, prolong the service life and improve the reliability and other aspects of significant effects.
4. Lubricating oil recovery and environmental protection
No waste oil recovery treatment, is conducive to environmental protection.
Self-lubricating graphite bearings as parts of the machinery industry, there is a broad sense of use. Much care has been taken to make the mechanical drive run properly. Bearings are divided into rolling bearings and sliding bearings. General sliding bearings will cause hair-pulling in the case of high load movement mode, foreign matter mixing, temperature conditions, oil supply, imperfect maintenance, and so on. Under the harsh conditions that general sliding bearings like this cannot be used, solid inlaid metal self-lubricating bearings give full play to the bearing’s due performance and hair-pulling resistance and realize the role of high-performance machinery and maintenance-free maintenance.
