Industrial Grade Ball Screw Fully Sealed Dustproof Module FSKSW-220 is a high-load linear transmission
module designed for harsh industrial environments. Its core features integrate precision transmission
and fully enclosed protection technology, suitable for precision positioning needs under harsh working
conditions such as dust and moisture.
Core Features
Fully enclosed protection structure
The stainless steel sealed cabin integrates double-lip seals to achieve IP54/IP65 protection, effectively
blocking the intrusion of dust, liquids and oil.
The protection design takes into account long-term corrosion resistance and is suitable for easily
polluted scenes such as food processing and chemical industry.
High-precision transmission system
Equipped with G1605 ball screw (diameter 16mm, lead 5mm), it supports repeated positioning accuracy
≤±0.01 mm to ensure precise linear motion control.
Low friction coefficient design (0.003~0.005) reduces energy consumption and improves running smooth
ness.
Strong load and high adaptability
Supports radial load ≥900 N (inferred value, based on the same series FSKSW-175 parameter enhancement
design), and the anti-turnover torque is increased to 30 N·m level .
The travel range 100–2000 mm can be customized, compatible with servo motors (maximum speed 6000 min⁻¹),
and meets the needs of diversified equipment integration .
Modular compatible design
Provides multi-directional motor installation interface (right/left/folding down) to simplify mechanical
layout .
Adapts to mainstream stepper motors and servo drives to reduce the complexity of system integration .
Typical application areas
Automated production lines: heavy workpiece handling robot arms, high-precision assembly platforms;
Environmentally sensitive equipment: food packaging machinery valve control, pharmaceutical
equipment filling mechanism; Outdoor industrial instruments: detection probe displacement system in
dusty environments, transmission positioning in humid conditions .
Operational restrictions and selection recommendations
Avoid using in explosive environments or areas with strong electromagnetic interference;
Extremely long strokes (>1.5 m) require auxiliary support to suppress high-speed vibration;
When selecting, it is necessary to comprehensively evaluate the dynamic characteristics of the load and
the stroke requirements, and give priority to verifying the matching accuracy requirements of the screw
grade (C5/C7)
The fully sealed, dust-proof module for industrial-grade ball screws offers the following core
advantages:
High-Performance Protection
A dual sealing structure (e.g., O-rings and labyrinth seals) and a protective cover design effectively
block the intrusion of dust, particulate matter, and moisture, reducing the increased friction and wear
caused by contamination. A protective film formed by a special dust-repellent lubricant further
enhances the isolation effect.
Extended Service Life
The sealed design reduces the erosion of contaminants on the internal components of the ball screw.
Combined with the use of wear-resistant materials (e.g., stainless steel and fluororubber), maintenance
frequency is significantly reduced and the equipment's operating life is extended.
Maintaining Motion Precision
The fully sealed structure prevents motion jamming or deformation caused by dust accumulation,
ensuring micron-level or even nanometer-level positioning accuracy even under high loads.
Adaptable to Complex Environments
The modular design allows customization for diverse industrial environments, including high and low
temperatures and humidity, balancing sealing strength with smooth operation without sacrificing
transmission efficiency.
Comprehensive Cost Optimization
The fully sealed module reduces equipment downtime and replacement costs by reducing failure rates
and maintenance requirements, offering outstanding cost-effectiveness over the long term.
The core advantages of the Industrial Grade Ball Screw Fully Sealed Dustproof Module FSKSW-220 are
as follows:
1. Fully Sealed and Dustproof Design
The fully enclosed structure, with an IP65 protection rating, effectively blocks the intrusion of dust, oil,
and cutting fluids, making it suitable for use in highly polluted industrial environments and significantly
extending the life of the screw and guide rails.
2. High Precision and High Rigidity
Equipped with a precision-ground ball screw, it achieves repeatability of ±0.01mm and increases axial
rigidity by over 30%, meeting the high-precision requirements of CNC machine tools, semiconductor
equipment, and other applications.
3. Low Friction and Long Life
The optimized ball recirculation system design
