Davoxin DVW7 Micro Wide Linear Guide

Description :

The DVW7 micro wide linear guide rail from Davoxin is a 7-segment wide micro linear guide rail (DVW wide series) launched by Davoxin. Its core features include widened slide rails, high rigidity, and high torque, achieving load and anti overturning capabilities far exceeding those of standard guide rails of the same specification in micro size. It is designed for precision transmission scenarios with limited space but high requirements for torque stability.

Davoxin DVW7 Micro Wide Linear Guide Material

All stainless steel (slides, sliders, steel balls, and accessories are all made of stainless steel, corrosion-resistant, suitable for humid/clean environments);

Alloy steel (high wear resistance, high load, suitable for working conditions with higher strength requirements);

Accuracy level: three levels: ordinary level (N), advanced level (H), and precision level (P), meeting different needs from automation to precision instruments;

Pre compression level: Supports gap pre compression (FZ), light pre compression (FC), and medium pre compression (F0), matching accuracy and rigidity as needed.

2、 Structure and Performance Characteristics

Wide width and high rigidity: The 14mm widened slide rail design allows for a static moment that is approximately three times that of the DVN7 standard model of the same specification. It can operate independently and stably on a single axis, significantly improving its anti overturning ability.

Goethe style four point contact: Steel balls make four point contact with the raceway, which can evenly bear loads in multiple directions such as up and down, left and right, and overturning. It has strong rigidity and high motion accuracy.

Steel ball anti drop: Built in micro retaining steel wire, the steel ball does not fall off when removing the slider, making installation and maintenance safer and more convenient.

Smooth and low-noise: The all steel ball circulation system is paired with precision retainers for smooth movement, low noise, and stable long-term accuracy.

Lubrication and dust prevention

Reserved oil injection hole on the end cap side, which can be refilled with a syringe for flexible maintenance.

Standard oil scraper, effectively preventing dust and dirt, extending service life.

Quality control: The slider is engraved with the model, logo, and production batch number, and the entire process is traceable; Passed ISO9001 quality management system certification.

3、 Applicable scenarios

Precision equipment: medical analyzers, laboratory automation platforms, semiconductor testing devices, optical measuring instruments.

Automation equipment: 3C electronic assembly, small robotic arm, dispensing/soldering equipment, precision positioning platform.

Single axis heavy-duty scenario: a small transmission mechanism with compact space but high torque and strong anti overturning ability.
