,RAIii. Detailed introduction of cross roller rotary disc bearings for RA type industrial robots

LYDZC90V,,.,,,LYDZCP2.,,,,,IC.LYDZC cross roller bearings are two columns of cylindrical rollers that are arranged vertically and crosswise through nylon isolation blocks in a 90-degree v-shaped roller track. Therefore, cross roller bearings can bear radial load, axial load, moment load and other multi-directional loads. The size of the inner and outer rings is miniaturized, the extremely thin form is close to the limit of the small size, and has high rigidity, and the precision of LYDZC cross roller bearing can reach level 2. Therefore, it is suitable for joint rotation of industrial robots, rotary table of machining center, precision rotary table, medical machine, calculator, IC manufacturing device and other equipment.

RA(,)RB,.,,.RA type (outer ring division type, inner ring rotation type) this series model is a compact type to reduce the thickness of inner and outer ring of RB type to the limit. Suitable for areas requiring light, compact design, such as robot and robotic hand rotation.

,,,,,,(0.001mm0.01mm,P5),.
Cross roller bearing is suitable for the need for carrying precision applications, such as robot arms, precision turntable, bearing the negative space design, so the bearing stiffness, can withstand a larger load, and has high precision (basic between 0.001 mm to 0.01 mm, beating bearing precision level is above the P5), cross roller bearing selection is the main bearing installation and size should be considered.
