Cross roller guides and linear guides are often compared.
In terms of construction, cross roller guides are separate units, making assembly more complex compared to linear guides.
Functionally, cross roller guides are suitable for short travel, high frequency and high precision applications.
Linear guides can reach up to 6,000 mm in single length and can be extended further. The transmission method is a Gothic groove structure, with steel ball transmission in the center, but its service life is not as long as that of cross roller guides.
In terms of sealing, linear guides are much better than cross roller guides as linear guides come with their own lubrication ports.
Cross roller guides are a highly rigid, precise and compact system for limited linear movement. By adopting unique R-type roller retainers that shorten the distance between cylindrical rollers, the effective contact length of cylindrical rollers is increased.
Unlike linear guides, cross roller guides have a lower installation height. Because they consist of two pairs of guides installed in parallel, the overall integrity of the machine tool with cross roller guides is better than that with linear guides. The tipping moment is also greater in cross roller guides, leading to significantly greater machine stability compared to linear guides.
Cross slide rails play an essential role in various fields, being widely used in OA machines and their peripheral machines, various measuring instruments, precision machines such as printed circuit board drilling machines or sliding base parts of optical testing instruments , optical workstations, manipulation mechanisms, x-ray apparatus, etc.
They are particularly significant in optical testing and optical workstations, contributing greatly to their functionality.
We all understand that optical testing instruments mainly deal with various measurement data, and different optical tests require specific adjustments. The use of cross rails ensures that the optical test instrument always reaches the precise location.
The application of cross rails at workstations is also substantial. For operators, the use of cross rails can minimize errors, inadvertently increasing the accuracy of various data.
Each of these two types of trails has its advantages. While everyone is probably familiar with linear slide rails, cross rails are less well known. Today, we will briefly discuss the advantages of cross rails!
1. They generate low friction, offering excellent stability during use, which guarantees product quality during the manufacturing process.
2. They have a large contact area and minimal elastic deformation, making the equipment more precise during manufacturing, ensuring compliance with product specifications.
3. They feature high load-bearing capacity, flexible structural design, easy installation, long service life, low mechanical energy consumption, high precision and fast speed. They can support loads from all directions, facilitating smooth, high-precision linear movements.
