- High-purity graphite filling and a stable solid lubricant, graphite content over 60%, enabling efficient operation in oil-free environments with long service life and maintenance-free use. - Made from high-strength brass CuZn24A16, offering strong wear resistance, high load capacity, and good high-temperature and aging resistance. - Suitable for areas where an oil film is difficult to form, such as reciprocating, rotating, and intermittent movements. Best for high-load, low-speed conditions, with excellent wear resistance and an extremely low coefficient of friction. - Precise tolerances and broad compatibility, thinner than rolling bearings, space-saving, and suitable for complex environments. - Typical applications: heavy-load, low-speed sliding or rotating assemblies; reciprocating guides and actuators; intermittent motion mechanisms such as indexing or cam follower systems.
