One advantage of SWBTEC is we can produce high precision preloaded crossed roller bearings for precision machine, like industrial robot, rotary tables, radar and so on.
SWBTEC has rich experience to produce cross roller slewing ring for roatry tables which need the bearing with axial and radial clearance not exceed 0.00mm and need preload, it also have requirement to the axial rated load and radial rated load.
The highest requirement of this kind of bearing is with high precision of outer dimension and inner dimension which sometimes need -0.03mm~-0.06mm and also require the surface runout 0.01mm.
Beside the non-standard drawing, we often produce some normal model products for timely deivery, including RB, RE, RU, CRB, CRBC, XSU, SX, CRBH series.
