Cross roller bearing applications and feature

  Cross roller bearing is a special type bearing. With inner ring segmentation and outer ring rotation. Due to its unique structure, it is commonly used as a joint bearing in industrial robots.The design of XR series cross roller bearings can provide high rotational accuracy and stiffness in a small space.Greatly saving material costs. This type of bearing is installed by crossing two sets raceways and rollers at a right angle.With adjacent rollers facing in opposite directions. Isolation blocks are installed between rollers. And support washers are also installed on the rollers.Which allows the two half columns of rollers to be accommodated in the same space.
The XR series cross roller bearing applications- suitable for high-speed machine tool applications. Such as vertical boring machines and vertical grinders.

Cross roller bearing applications feature:
1. Excellent rotational accuracy: The internal structure adopts rollers arranged in a 90 ° perpendicular cross pattern. With spacers or isolation blocks installed between the rollers to prevent tilting or friction. Effectively preventing an increase in rotational torque.
2. Simplified installation: Standard cross roller bearings are divided into two parts: an outer ring or an inner ring.Which are fixed together after the rollers and retainers are installed.
3. Large axial and radial loads: Because the rollers are arranged perpendicular to each other through spacers on a 90 ° V-shaped groove surface.This design allows bearings to withstand large radial loads, axial loads, and torque loads in all directions.
4. Significantly saving space: The inner and outer ring sizes are minimized, especially for ultra-thin structures that are close to the limit of small size.

Cross roller bearing applications range:
Precision rotary indexing table for machine tools, vertical and horizontal boring machines, vertical grinders, rotary surface grinders.Large gear hobbing machines, gun and radar rotary tables, large radio and optical telescopes. Rotary cameras, steering pivot and continuous casting machines. Height restricted pivot microscope tables, pole center support shafts. Rotary bogies, welding brackets, rotary assembly fixtures. Industrial robots, precision rotary workbenches. Medical equipment, measuring instruments IC manufacturing equipment, etc.
