Linear Bearings

Linear bearings divided into metal and plastic linear bearings linear bearings
Metal Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Since carrying the ball point contact with the shaft, so the use of small loads. With minimal friction ball rotation, which can obtain high-precision smooth movement.
Plastic Linear Slewing bearing s a self-lubricating properties of linear motion system for metal linear bearings biggest difference is that the metal is rolling friction linear bearings, bearings and point contact between the cylinder axis, so that for low-load high-speed movement; while plastic linear bearings are sliding friction between the bearing and the cylindrical shaft surface contact, so this is suitable for high load low speed movement;Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical, assembling the drum-shaped roller bearings.
Spherical roller bearings with two rollers, the main path of a load, but also can withstand axial load in either direction. A high radial load capacity, especially suitable for heavy work loads or vibration, but can not afford pure axial load. This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate concentricity error.
Spherical roller bearings have two symmetrical spherical roller, there is a common spherical outer ring raceway, and the bearing inner ring with two axis tilt angle of the roller, with good self-aligning performance, when the axial force bending or install a different heart is still bearing normal use, transfer concentric with the bearing dimension series varies, generally allow aligning angle is 1 to 2.5 degrees, the type of bearing a larger load capacity, in addition to radial loads bearing can withstand two-way effect of axial load, has good impact resistance, generally spherical roller bearings allow lower operating speed
