the other one is a lysn Cylindrical roller bearing

About Cross cylindrical roller bearings Crossed roller bearings , there are two classes , one is a cross cylindrical roller bearings , and the other one is a lysn paired angular contact ball bearing  ; cross roller bearings in a foreign country has a long history of application , but in recent years, the country is only just entered the public view , due to its particularity and has incomparable superiority of other bearings are widely used. Main Features 1 , with excellent precision crossed roller bearings rotating internal structure of 90 ° roller arranged perpendicular cross (which is also cross roller bearings origin of the name ) , equipped with roller spacing between the cage or isolation block , You can prevent the roller tilt cargo rolling mill mutual observation between the child , effectively preventing the increase of rotational torque . In addition , the party will not occur in contact roller locking phenomenon or phenomena ; same time as standard crossed roller bearing inner ring is segmented structure , the gap can be adjusted , even if they are pre- applied pressure, but also can get high-precision rotary motion . 2, the operation simplifies installation standard lysn china bearing manufacturer outer ring is divided into two parts or inner ring , after loading roller and cage were fixed together , you can fine-tune the installation bolts and flange connection to to achieve the desired load state , so the mounting operation is very simple. 3 , bear large axial and radial loads because the roller is arranged vertically spaced from each other by the holder in the V-shaped groove raceway 90 ° , this design makes cross roller bearings can withstand greater loads in all directions radial load, axial load and moment loads
