High-strength brass oil groove bushings are bearings that use oil grooves for lubrication, featuring traditional tin-bronze bearing capabilities. However, due to the use of high-strength brass (such as ZCuZn25Al6Fe3Mn4), their hardness is doubled, allowing them to last twice as long as standard bronze bushings in low-speed applications and to withstand heavy loads. This material is free from substances toxic to humans and the environment, such as mercury, cadmium, and hexavalent chromium, and contains much less lead than the limits set by the EU’s RoHS Directive, making it an environmentally friendly metal material.
Oil-less bushings, also known as self-lubricating bushings, are bearings that can operate under no or minimal lubrication conditions. They are typically made from high-strength brass with solid lubricants (like graphite) embedded, suitable for conditions requiring relative heavy loads at low speeds or complex movements such as linear and rotational motion. High-strength brass (SP2), also known as CAC304 or HBsC4, is a multi-element, wear-resistant, corrosion-resistant aluminum brass with high strength and hardness.
Specific designs such as dual oil grooves and figure-eight grooves on oil groove bushings are used to store and guide lubricating oil to ensure the bearing’s lubrication. Circular grooves are concave channels around the bearing’s periphery, used to secure the bearing or serve as channels for storing and distributing lubricating oil. These designs help enhance the bearing’s performance and lifespan.
Custom production refers to the design and manufacture of products according to a customer’s unique requirements rather than standard sizes or specifications. This means customers can customize the size, oil groove design, and other characteristics of the oil groove bushings to meet specific operational conditions and performance needs.
In summary, high-strength brass oil groove bushings, oil-less bushings, and designs like dual oil grooves, figure-eight grooves, and circular grooves are all aimed at enhancing bearing performance and durability in specific applications, while custom production provides flexibility to meet specific customer needs.
The design of copper bushings with dual oil grooves, figure-eight grooves, and circular grooves primarily aims to enhance lubrication effects and extend the service life of equipment. This design incorporates multiple oil groove structures to ensure the even distribution and effective storage of lubricating oil.
