Overview
MV cross needle roller guide is a high performance linear motion system, which is widely used in industrial applications requiring high precision, high rigidity and high stability.
Basic composition
MV cross needle roller guide is mainly composed of two guide rails with V-shaped raceway, needle roller cage and precision machining needle roller and other components. The needles are arranged in order in the cage and rolled on the V-shaped raceway to achieve high precision linear movement.
Material and hardness
MV cross needle roller rails are usually made of high hardness materials, such as grade GCR15(AISI2100) bearing steel or NO.1.2842 steel. The hardness of these materials is usually between HRC58 and HRC62, ensuring high wear resistance and long life of the guide.
Characteristics and advantages
High precision:
MV cross needle roller guide adopts precise machining and assembly process to ensure extremely high positioning accuracy and repeated positioning accuracy.
The contact area between the needle roller and the raceway is large, and the rolling friction resistance is small, which helps to reduce the error and improve the processing accuracy and measurement accuracy of the equipment.
High rigidity:
The cross-arranged needle roller design enables the guide system to withstand loads from all directions with excellent rigidity and stability.
The close combination of needle cage and guide rail further enhances the rigidity of guide rail and reduces vibration and deformation.
Low friction resistance:
When the needle rolls on the track, the friction resistance is small, the stability is good, the starting friction is small, and the following performance is good.
This helps to reduce energy consumption, improve the operating efficiency of the equipment, and reduce wear and heat generation.
Long life:
MV cross needle roller guide has a long service life because of its excellent material, high machining precision and reasonable structure design.
Regular maintenance and maintenance can further extend the service life of the guide rail.
Various specifications available:
MV cross needle roller rails are available in a variety of specifications and sizes, such as 3015, 4020, 5025, 6035, 7040, 8050, etc., to meet the needs of different equipment and application scenarios.
