Single row crossed cylindrical roller slewing ring bearings are simple in design, consisting of a one-piece inner and outer ring and cylindrical rollers separated by polyamide spacers and generally protected by integral seals. Single row crossed cylindrical roller slewing ring bearings can accommodate heavy radial loads and medium axial loads as well as tilting moments. These LYHY slewing ring bearings are intended for bearing arrangements where stiffness is important or zero operational clearance or preload as well as constant resistance to rotation are required.
 
Single row crossed cylindrical roller slewing ring bearings require tighter specifications for the flatness and stiffness of the support surface than single row four-point contact ball slewing ring bearings. 




Single  row crossed roller slewing ring bearings can be manufactured :

      Single  row crossed roller slewing ring bearing without a gear
      Single  row crossed roller slewing ring bearing with an internal gear
      Single  row crossed roller slewing ring bearing with an external gear




LYHY single-row crossed cylindrical roller slewing ring bearing is similar to four-point contact ball slewing ring bearing, with only single-row short cylindrical rollers. The axes line of adjacent cylindrical is 90° Crossed spread. There are two raceways in outer and inner ring. The section of raceway is linear. Half of the rollers bear down axial loading and half bear up axial loading. So a crossed roller bearing can bear radial loading, axial loading and moment loading, loading from all directions.

Single-row crossed cylindrical roller slewing ring bearing is widely used in joint parts and rotating parts of robots, revolving table of machinery process center, machinery hand revolving part, medical equipments, crane transportation machinery, engineering machinery and army products.
