In industrial environments filled with dust and iron filings, lead screw module jamming frequently causes equipment shutdowns and precision loss. Selecting suitable fully enclosed dust-proof lead screw modules fundamentally solves such failures.
-
Sealing Structure Selection
Choose enclosed modules equipped with internal-pressure multi-layer metal scrapers or elastic lip seals with self-compensation function. Adopt fully welded or integrally bent seamless housings to block dust intrusion through assembly gaps.

Positive Pressure Air Curtain Auxiliary Protection
Integrate air inlet ports on both end supports. Filtered dry compressed air creates slight internal positive pressure to stop reverse inflow of iron filings, and continuous airflow cleans scraps accumulated outside sealing lips.

Chip Removal Channel Design
Install chip outlets with check valves or labyrinth grooves at the bottom or end caps. Tiny internal dust is discharged via gravity and vibration to avoid abrasive paste formed by accumulated metal debris.

-
Internal Lubrication Scheme
Use high-adhesion extreme-pressure grease matched with automatic timed grease filling systems. Fresh grease pushes out contaminated waste grease to eliminate three-body abrasive wear induced by suspended iron particles.

Material & Surface Treatment
Carburized or high-frequency quenched steel with hard chrome or DLC coating is adopted for screws and rails to boost hardness and scratch resistance. Flexible, wear-resistant scraper materials prevent cuts from sharp iron filings.

Maintenance & Monitoring System
Schedule regular cleaning and grease replacement based on operating hours. Run low-speed empty strokes for chip removal during downtime. Reserve sensor interfaces for real-time friction anomaly monitoring on heavy-duty stations.
