         RB70045 Crossed roller bearings are bearings for precision applications that correspond in their dimensions to ISO dimension series 18 in accordance with DIN 616. They comprise outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and is held together by three retaining rings. Due to the X arrangement of the rolling elements, RB70045 Cross Roller bearing can support axial forces from both directions as well as radial forces, tilting moment loads and any combination of loads with a single bearing position. This allows designs with two bearing positions to be reduced to a single bearing position.RB70045 Cross Roller bearing are very rigid, have high running accuracy and are supplied with normal clearance, little clearance or preload.

         RB70045 Cross Roller bearing ‘s outer rings can be easily located in the adjacent construction by means of clamping rings.The inner and outer rings, which are separable, are secured to RB70045 Cross Roller Ring body after the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other. Thus, it is easy to handle the rings when installing the Cross Roller bearing The spacer retainer keeps rollers in their proper position,thereby preventing them from skewing. This eliminates friction between rollers, and therefore secures a stable rotation torque. the cross array of rollers allows a single RB70045 Cross Roller bearing unit to receive loads in all directions, increasing the rigidity to three to four times greater than the conventional type.
