Crossed cylindrical roller bearing is one kind of bearing whose rollers are square crossing arranged between outer ring and inner ring. The rollers contact the raceway in linearity, so this bearing has better rigidity and less elastic strain. At the same time, this bearing can carry radial load, axial load and moment load simultaneously. They are especially suitable for high rigidity and high running accuracy applications.


Crossed cylindrical roller bearing contains double sets of raceways and rollers which are brought together at right angle with alternate rollers facing in opposite directions.


Unlike crossed roller bearing, the rolling elements of cross tapered roller bearing are tapered rollers. The height of cross section is similar to single row bearing, thus the design of bearing housing is simplified. The steep angle tapered geometry makes the effective span of the bearing much greater than the width of the bearing itself. Cross tapered roller bearings can carry high overturning moment, thus they are widely used in large hobbling machine, industrial robot, high speed vertical lathe, high precision working table, vertical boring machine, and spindle of grinding machine etc.


According to customer's needs, CHG is on the position to produce different kinds of crossed roller bearing:
HGRA ( outer ring division, inner ring rotation, slim type);
HGRA/C ( single split structure, this model can be used also for outer ring rotation );
HGRB ( outer ring division, inner ring rotation );
HGRE ( inner ring division, outer ring rotation );
HGRU ( integrated inner/outer ring type);
HGCRBH ( integrated inner/outer ring type, slim type);
HGCRB/CRBC ( inner ring division, outer ring rotation);
HGSX ( outer ring division, inner ring rotation, slim type) and etc.
And two kinds crossed tapered roller bearings: HGXR, HGJXR type.
The dimensions of CHG cross roller bearings ID range from 80-1250mm. The precision includes P5,P4,P2.
