Industrial robot bearings - crossed roller bearings application advantages

1.Excellent rotational accuracy: the rollers are equipped with spacer or isolation blocks, which can prevent the rollers from tilting or rubbing against each other and effectively prevent the increase of rotational torque; moreover, the inner and outer rings are divided structure, the clearance can be adjusted, and even if pre-pressure is applied, high precision rotational movement can be obtained.

2.Simple operation and installation: the outer ring or inner ring, which is divided into two parts, is fixed together after the roller and cage are installed, so the installation is very simple.

3.Can withstand large axial and radial load: because the rollers in a 90 ° V groove rolling surface through the interval keeper is arranged vertically with each other, this design makes crossed roller bearings can withstand large radial load, axial load and moment load and other loads in all directions.

4.Significant space saving: The inner and outer ring dimensions of crossed roller bearings are miniaturised, especially the ultra-thin structure is close to the limit of small size and has high rigidity, so it is very suitable for the joint parts or rotating parts of industrial robots.

Industrial robot bearings - the application advantages of thin-walled bearings with equal cross-section

1.To meet the requirements of various robot applications: in order to get the low friction torque, high rigidity and good rotary accuracy, the equal-section thin-walled bearings use small outer diameter steel balls, and the use of hollow shafts ensures light weight

2.Structure type applicability: equal cross-section thin-walled bearings because of a variety of structural forms, such as thin-walled 6700, 6800 series have a variety of dust cover form, with flange form, stainless steel form, wide form, etc., greatly expand the scope of application in industrial robots.
