Plugged graphite bearings reduce the need for regular maintenance, as they do not require external lubrication. This feature is particularly advantageous in applications where lubrication is difficult or where contamination from lubricants is a concern.
The spherical design of these bearings allows for angular misalignment, making them ideal for applications where shaft alignment is a challenge. This flexibility in alignment not only simplifies installation but also enhances the operational lifespan of the bearings by reducing stress on the components.
High Load Capacity and Durability
One of the key attributes of the 500 Spherical Bearings is their ability to handle high loads. This capability stems from their robust construction, which typically involves high-grade materials such as high carbon chromium bearing steel. The durability is further enhanced by the presence of the graphite plugs, which provide continuous lubrication, minimizing wear and tear.
Applications: Versatility Across Industries
The versatility of the 500 Spherical Bearings Unit is evident in its wide range of applications. From heavy machinery in the construction industry to precision equipment in manufacturing, these bearings are suited for various environments and tasks. Their ability to withstand high loads and oscillating movements makes them particularly useful in sectors like automotive, aerospace, and renewable energy, where reliability and performance are critical.
Environmental and Economic Benefits
The self-lubricating nature of these bearings not only reduces maintenance requirements but also presents significant environmental benefits. By eliminating the need for lubricants, these bearings contribute to a cleaner operational environment and reduce the risk of contamination. Economically, the long service life and reduced maintenance needs of these bearings translate to lower operational costs over time, making them a cost-effective solution for many businesses.
Conclusion: A Step Forward in Bearing Solutions
The 500 Spherical Bearings Unit with plugged graphite is a testament to the continuous evolution in bearing technology. By offering high load capacity, durability, and self-lubricating properties, these bearings stand out as a superior choice for a wide array of applications. Their design not only meets the current demands of various industries but also paves the way for more innovative and efficient mechanical solutions in the future.

Joint bearing characteristics The structure of joint bearing is simpler than rolling bearing, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. The joint bearing is generally used for low-speed oscillating motion (i.e. angular motion), because the sliding surface is spherical, it can also be tilted in a certain angle range (i.e. spherical motion), and can still work normally when the support shaft and the shaft housing hole are not concentric.
Self-lubricating spherical plain bearings are self-lubricating bearings that can be rotated or swung in any direction.
The self-lubricating spherical joint bearing is a kind of self-lubricating performance, that can be rotated or swung in any direction. It has the high bearing capacity, small coefficient of friction can automatically adjust the center can simultaneously withstand radial and axial load, self-lubricating maintenance-free, long service life, a wide range of applications, and other characteristics. Since the end of the last century, the product has been put on the market for the domestic water conservancy projects and various mechanical equipment to provide different specifications of self-lubricating joints bearing tens of thousands of sets, the actual use of many water conservancy projects proved that our company developed and produced a stable and reliable performance of self-lubricating joint bearing, in the national key water conservancy projects gradually replace the imported, representing the technology of domestic self-lubricating joint bearing reached the international advanced level!
Self-lubricating joint bearings are divided into three categories, namely radial joint bearings, thrust joint bearings, angular contact joint bearings
Self-lubricating thrust joint bearings: Self-lubricating materials have excellent friction reduction, wear-resistance and self-lubrication, and also have High bearing capacity and good dimensional stability, can meet the special self-lubricating joint bearings for hydraulic machinery. The self-lubricating material has excellent friction reduction, wear-resistance and self-lubrication.
Joint bearings can withstand large loads. According to its different types and structure, it can bear radial load, axial load or radial, axial at the same time combined load. Due to the inner ring of the outer spherical surface with composite materials, so the bearing can produce self-lubrication in the work. Generally used for low-speed swing movement, and low-speed rotation, but also in a certain angle range for tilting movement, when the support shaft and shaft shell-hole is not the center degree is large, but still can work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.
