Radial hydrostatic bearing technology analysis<\/strong><\/h2>\n

Working principle<\/strong><\/h3>\n

Radial hydrostatic bearings<\/strong><\/a> use an external oil supply device to press the lubricating medium into the bearing gap to form a stable hydraulic oil film. The static pressure effect generated by the oil film effectively isolates the contact of the friction pair and achieves a nearly zero-friction operating state. This non-contact support method is particularly suitable for industrial scenarios with strict requirements on precision and stability.<\/p>\n
