What Is a Crossed Roller Table?
A crossed roller table is a table that incorporates precision rollers with retainers in alternating tolerances between a high-precision V-shaped groove on the underside of the table and the base. The table is supported by a number of rollers and is capable of linear motion.
Crossed roller tables are used in office automation equipment, IC processing machines, etc., because of their high rigidity in various directions and high-precision linear guidance.
There are also cross-roller rings and cross-roller bearings, which have a circular groove instead of a straight V-shaped groove and can rotate. The table or shaft is supported by crossed roller table, which has the same characteristics as crossed roller table.
Uses of Crossed Roller Tables
Crossed roller tables are widely used in linear motion sections that require high precision and high rigidity. Specifically, they are used in office automation equipment and peripherals, various measuring instruments, IC manufacturing equipment such as printed circuit board drilling machines, and medical equipment.
Crossed roller bearings are used in a wide range of applications, including joints and swivel parts of industrial robots, joints of robot suits for nursing care, swivel tables of machining centers, precision rotary tables, measuring instruments, and IC manufacturing equipment. Furthermore, the applications are expanding to the cutting-edge fields of aeronautics and space.
Features of Crossed Roller Tables
Crossed roller tables have V-shaped polished guide grooves on the underside of the table, and the rollers are incorporated between the base and the guide grooves using retainers that alternately contact both sides of the V-shaped guide grooves. The table is supported by a number of rollers, enabling linear motion. And two guide grooves are arranged in parallel to support loads in multiple directions to increase rigidity.
The rollers, guide grooves, and base are highly accurate, and the gap can be adjusted with a screw to apply pressure. Since it is supported on two intersecting surfaces, it has high rigidity even when subjected to loads in the vertical and horizontal directions and bending moments in each direction.
In addition, types with V-shaped grooves, bases, rollers, and retainers made of stainless steel have features of long life and corrosion resistance, and can easily provide high-precision linear guidance simply by mounting with bolts.
Rotatable cross-roller rings are characterized by high rotational accuracy. Roller skew and mutual friction between rollers are prevented, and stable rotational torque can be obtained.
