Rolling linear guides are generally referred to as linear guides. Depending on personal usage habits, they are sometimes also called linear rails, ball guides, machine tool guides, precision guides, rolling guides, roller guides, etc.
Linear guides generally have the following characteristics
Large load capacity and high stiffness
On the spherical raceway surface of the guide rail, arc-shaped grooves are processed by form grinding, which increases the contact area and can When bearing larger allowable loads, impact loads and heavy loads, the load-bearing contact area increases, improving the stiffness of the system. The rolling linear guide pair can withstand various loads in up, down, left, and right directions and can be installed and designed according to different purposes.
High operating accuracy
According to needs, increase the preload appropriately to ensure that the steel ball will not slide, achieve smooth movement, and reduce the impact and vibration of the movement. At the same time, the movement of the rolling linear guide pair relies on the steel ball The rolling is realized, the friction resistance of the guide rail pair is small, the difference between dynamic and static friction resistance is small, and crawling is not easy to occur at low speeds. It has high repeatability positioning accuracy and is suitable for moving parts that frequently start or change direction.
Strong dust-proof sealing ability
The slider is equipped with sealed end caps at both ends, and a sealed bottom sheet is used at the bottom, which has good dust-proof performance. At the same time, the guide rail mounting holes are equipped with screw caps to prevent dust accumulation, thereby ensuring the product's lifespan and adaptive performance.
Installation
Due to the use of precision processing technology, the guide rail has high straightness, the hole spacing error of the guide rail mounting holes is small, and installation is easy. At the same time, the guide rail pair is easy to disassemble and assemble because the slider is equipped with a steel wire cage. It can also provide users with false guide rails for assembly.
Good changeability
The rolling linear guide pair has a regular structure and is easy to carry out high-precision measurements. It is easy to increase the slider, update the slider and adjust the pretightening force. The installation dimensions comply with national standards and are basically the same as those of foreign
manufacturers in the same industry. Due to good interchangeability, the guide rails can be extended to unlimited lengths.
