Davoxin DVN9H-N standard micro guide rail

Description :

Davoxin DVN9H-N standard micro guide railIt is a 9-specification standard micro linear guide rail (DVN standard series) produced by Dawoxin, positioned as a precision transmission component with elongated slider, medium load, and high rigidity. It provides stronger load and anti overturning ability than standard slider in a compact size, and is suitable for automation and precision equipment scenarios with limited space but high stability requirements.

Davoxin DVN9H-N standard micro guide railModel meaning and core specifications

Model Definition

DVN: Dawoxin Standard Micro Rail Series

9: Slide width 9 mm (specification 9)

H: Long type slider

N: Normal Grade accuracy

Material Options

Alloy steel: high hardness, high wear resistance, universal type (under normal working conditions).

All stainless steel: The slider, slide rail, steel ball, and retainer are all made of SUS stainless steel, which is rust resistant and corrosion-resistant, suitable for humid/clean environments.

Accuracy and Preloading

Accuracy level: N ordinary level (optional H, P precision level)

Pre compression level: FZ (gap), FC (light pre compression), F0 (medium pre compression)

Structure and Real Performance Characteristics

1. Goethe style four point contact (45 ° contact angle)

Two columns of steel balls form a four point equal load contact with the raceway, which can evenly bear loads in multiple directions such as up and down, left and right, and overturning. It is rigid, stable, and has reliable positioning accuracy.

2. H elongated slider → higher load and rigidity

The extended slider structure significantly increases the rated load, static moment, and anti overturning ability compared to the standard slider of the same specification (DVN9C), making it suitable for single axis medium load or cantilever installation scenarios.

3. Steel ball retainer+anti drop design

Built in micro retaining steel wire, the steel ball does not fall off when removing the slider; Precision retainers ensure smooth operation, low noise, and interchangeability within the precision range.

4. Full steel ball circulation+smooth and low-noise

The all steel ball reflux structure has low friction, smooth walking, and slow precision degradation during long-term use.

5. Lubrication and dust prevention (real configuration)

Side mounted oil injection hole (without oil nozzle, limited by micro 9-size space), capable of refilling oil with a syringe

Standard oil scraper, effectively preventing dust and dirt, extending lifespan

6. Quality and traceability

Sliding block engraving model LOGO、 Production batch number; Controlled by ISO 9001 quality system.
