Cross tapered roller bearings consist of two columns of mutually perpendicular bearing raceways and a set of tapered rollers arranged at a 90 ° angle. The rollers are separated by nylon isolation blocks to prevent tilting and friction between the rollers, reducing rotational torque. It can withstand combined loads such as radial loads, axial loads, and overturning moments.In addition, the inclination angle and conical geometry of the bearing will protect the bearing center of each raceway along the axis, and finally, the total effective bearing distance range is many times larger than the width of the bearing itself. Cross tapered roller bearings can withstand high overturning moments and are ideal for turntable bearings used in machine tools such as high-speed vertical lathes, vertical boring machines, and grinders.
These bearings are also suitable for other space limited shaft and base applications or situations where the center of gravity of rotating parts is required to be the lowest.
Main character and Application
1. High precision: The accuracy can reach P4 level.
2. High rigidity: This series of bearings comes with preload and
can be adjusted to achieve optimal preload.
3. High load-bearing capacity: capable of withstanding axial
loads, radial loads, overturning moments, and high anti
overturning stiffness.
4. High speed: The rolling elements perform pure rolling during
motion, so the maximum speed is much higher than that of cross
cylindrical roller bearings.
5. Low friction: The friction torque is much lower than that of
cross cylindrical roller bearings, resulting in low starting torque.
6. Compact design, requiring minimal installation space.
These characteristics make it very suitable for applications in many situations where space is limited, the center of gravity of the rotating mass is as low as possible, and high rotational speed is required, such as precision circular indexing worktables for machine tools, vertical and horizontal boring machines, vertical grinders, rotary surface grinders, vertical lathes, large gear hobbing machines, rotary towers, large telescopes (radio, optical),rotating cameras, industrial robots, etc.
The cross tapered roller bearing adopts a large cone angle and cone geometry design, which makes the overall effective span of the bearing larger; The intersection point of the extension line of the rolling surface of the tapered roller is located on the rotation center line of the bearing, which allows the tapered roller to perform pure rolling during the motion, avoiding relative sliding with the raceway. Therefore, the maximum speed is much higher than that of the crossed cylindrical roller bearing, and the friction torque is also lower than that of the crossed cylindrical roller bearing.
