Plain Bearing Flywheel Self-Lubricating Bronze Bushings Metric Size are precision-made components designed to provide smooth and efficient operation in flywheel systems. Constructed from high-quality bronze material, these bushings are self-lubricating, eliminating the need for regular lubrication and maintenance.
The metric size of these bushings ensures a perfect fit in various flywheel applications, allowing for seamless integration into existing systems. The bronze material offers excellent wear resistance and durability, ensuring long-term performance and reliability.
The self-lubricating feature of these bushings significantly reduces friction and heat generation, resulting in smoother and more efficient operation. This not only improves the overall performance of the flywheel system but also extends the service life of the bushings themselves.
Whether you're upgrading an existing flywheel system or installing a new one, Plain Bearing Flywheel Self-Lubricating Bronze Bushings Metric Size are an ideal choice for enhancing performance and reducing maintenance costs. Contact us today to learn more about these bushings and how they can improve the efficiency and reliability of your flywheel system.

At present, the novel figure 8 oil groove technology has been used more and more in large diameter copper sleeves of heavy mining equipment at home and abroad. This technology fully takes into account the uniform lubricating oil in place when the parts are running, smooth discharge of slag, good lubrication performance, small wear, and straight service life of copper sleeve
Metal-based self-lubricating bearing Groove Bearing Bronze Big Size.
In construction machinery, there are 8 type oil grooves in the inner holes of many sleeve parts. For the processing of this kind of product, the traditional processing method is the single production usually adopts the fitter to draw the line and then uses the oil groove chisel to pick out, and the mass production uses the special machine tool to process. With the increasing degree of nc machining equipment, NC machining is gradually replacing traditional machining. Practice has proved that numerical control turning method to process figure 8 spiral groove has high machining flexibility and adaptability, and can ensure the machining quality and economic benefit of parts.

The metal base of the metal base self-lubricating bearing has good wear resistance, and the solid lubricant containing solid can continuously provide lubrication for the friction surface to ensure the self-lubricating performance of the bearing.
1. When the blank copper sleeve is finished, first rough process, and make a fine billet copper sleeve with a 2mm margin on one side.
2 and production of oil tank, and both vertical oil tank, the annular groove, spiral groove, or cross groove, the tooling according to the first, and then processing groove, must take into account when processing problem of allowance, tank to do deep and wide, not according to normal process, or at the time of finish machining copper set of finished product will find a problem, need a second car processing, so it will be a great trouble.
3. After the finished copper set, the edge of the oil groove should be made into an R Angle to facilitate the flow of oil and make it more beautiful without hurting hands.
