Cross Roller Bearings
UTOT® Cross Roller Bearings have two kinds. One is Crossed cylindrical roller bearing. 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.
The dimension of the inner and outer rings is a minimum to miniaturization, especially extremely thin type is close to the limit of small size, and high rigidity, so it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical instrument, measuring instruments, IC manufacturing machines, and etc..

The other is Crossed tapered roller bearing. Crossed tapered 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 Crossed 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. Crossed 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.

1. High precision: precision at P4, P4, P2.
2. High rigidity: these series bearings are with preload.
3. High load capacity: can support radial load, axial load, and tilting load.
4. High speed: rollers rolling in the raceway, so the limited speed of crossed taper roller bearings is higher than that of crossed cylindrical roller bearings.
5. Low friction: the frictional torque of crossed taper roller bearings is much lower than that of crossed cylindrical roller bearings
