Linear bearing SC UU type is a compact aluminum casing unit incorporating the standard Linear Bush. This model can easily be mounted simply by securing it to the table with bolts.


Linear bearings are used together with hardened linear shaft. An infinite linear motion systems. Ball and hardened shaft because it is the contact point, allowing the load is small, but linear movement with minimum friction, high precision, fast movement. It is used to pass linear motion.


SC UU series Linear Ball Bearing Slide Block Units complementary to linear ball bearings.They usually consist of a light-weight, aluminium housing to provide high strength and stiffness. Compact design with High load carrying capacity, Linear Motion Bearing Unit is a rolling friction supporting element that usually used for linear motion mechanical parts with small friction.Coordinate with Linear Motion Shaft, recirculating balls provide unlimited stroke at low friction movement, permit temperature within 80 degree Celsius.



Linear bearings are widely used in electronic equipment, pull tester and the digital three-dimensional coordinate measuring device, such as precision equipment, as well as multi-axis machine tools, press, tool grinder, automatic gas cutting machine, printer, card sorting machine, food packaging machines and other industrial machinery sliding components.
