Linear bearing and classification method

Linear bearing is a kind of linear motion system unit with a low cost production parts and used for unlimited travel used with cylindrical shaft. Because point contact ball bearing with shaft, so using the load is small. Ball to the smallest friction spinning, thus can get high precision of smooth movement. Linear bearing and guide shaft (quenching line shaft), as an infinite linear motion system. Load ball and quenching shaft because it is a point contact, the allowable load is small, but the linear motion, the minimum friction resistance, high precision, fast and stable movement. Widely used in electronic equipment, tensile testing machine and digital 3 d coordinate measuring equipment such as precision equipment, and multi-axis machine tools, automatic punching machine, tool grinding machine, gas cutting machine, printer, card sorting machine, industrial machinery, such as food packages installed the sliding parts.

Linear bearing the main categories:
Linear ball bearings according to specification system function and installation method of classification of different models
According to the specification standard points:
1, the standard specifications (metric size as standard, with the straight axis diameter tolerance is commonly h7, Asian countries have used)
2, the standard specifications (on the basis of inch size. Also have metric size, with the straight axis diameter tolerance is commonly g6,) is commonly used in European countries
Linear bearing according to the shape of points:
1, straight type (shape such as cylinder, spring is commonly used in installation, for special occasions requiring small installation size)
2, flange type (end or middle flange, with installation can use screw to install, general component is circular flange, square and trimming type three)
3, open rack (shape, such as straight, appearance has axial slitting, used to need clearance adjustment, large openings and small openings)
According to the performance points:
1, ordinary (generally use of performance requirements)
Type 2, super (long life and large load performance requirements)
