FSKT-120 High-load Long-travel Semi-enclosed Belt Sliding Module Introduction
FSKT-120 is a belt-driven linear module designed for heavy-load and long-distance automation
scenarios. It adopts a semi-enclosed protection structure to balance high-speed operation and basic
dust prevention requirements. Its core features are as follows:
🔧 I. Core structure and design
Synchronous belt drive system: equipped with low backlash synchronous belt and high-precision pulley
set, supports high-speed linear motion (maximum speed ≥5m/s), suitable for dynamic applications such
as logistics sorting or continuous feeding
Semi-sealed protection design: The top flexible dust barrier combined with the labyrinth side seal
effectively blocks dust intrusion, with a protection level of IP40, suitable for slightly polluted environments
High rigidity and lightweight frame: One-piece aluminum alloy base (30% weight reduction), enhances
structural stability and suppresses high-speed vibration, and surface anodizing improves durability
📊 II. Key performance parameters
Parameters Specification range
Maximum load 50–100kg (horizontally installed)
Effective stroke 300–8500mm (customizable)
Repeat positioning accuracy ±0.05mm
Protection level IP40 (standard)
Note: For ultra-long travel (>3m), additional support rails are required to prevent belt sagging
⚙️ III. Technical advantages
High-speed and low-noise operation: extremely low friction coefficient, noise ≤50dB, suitable for quiet
environments such as medical equipment or laboratories
Modular expansion: compatible with direct connection of stepper/servo motors, supports multi-axis
system splicing, and simplifies industrial automation integration
IV. Typical application scenarios
Heavy-duty logistics transmission: high-speed handling of express sorting lines (load ≤100kg, travel up
to 8.5m)
Industrial automation assembly: PCB board assembly line transfer or packaging machinery positioning
platform
Long-travel and light-load scenarios: replace traditional chain drive mechanisms to reduce maintenance
costs
The High Load Long Stroke Semi-closed Belt Slide Module FSKT-120 is a high-load, long-stroke semi
-closed belt slide module designed for heavy-duty industrial automation applications. Its semi-enclosed
structure effectively protects against dust and foreign matter intrusion, ensuring long-term stable
operation in harsh working conditions. The module utilizes a high-rigidity synchronous belt drive,
supporting large loads (refer to the technical documentation for specific parameters) and long strokes.
Combining high precision and durability, it is suitable for applications with stringent load capacity and
stroke requirements, such as logistics sorting, heavy assembly, and machine tool loading and unloading.
The FSKT-120 is an industrial-grade, belt-driven linear module with a semi-enclosed design, specifically
developed for high-load, long-stroke applications. Its key features include:
Structural Design: The semi-enclosed housing effectively protects against dust, and the reinforced dual
-guide rail structure ensures a 60kg horizontal load capacity.
Motion Performance: Standard travel ranges from 50-1050mm (customizable), coupled with a high-
precision synchronous belt drive, achieves repeatability of ±0.03mm.
Drive Compatibility: Compatible with stepper and servo motors, supporting a wide voltage input range
of 48-100V.
Expanded Functionality: Optional communication modules and auxiliary power connectors facilitate
system integration.
This module is suitable for industrial automation applications requiring long-distance, precise transmiss
ion, such as semiconductor equipment and laser processing.
The High-Load, Long-Stroke Semi-closed Belt Slide Module FSKT-120 offers the following key
advantages:
High-Load and Long-Stroke Design
Utilizing an enhanced synchronous belt drive and reinforced guide rail structure, it supports load
capacities exceeding 36.2 kg and a travel range of 50-4000 mm (up to 8 m with special assembly),
meeting the needs of handling large workpieces.
Semi-Enclosed Protection and Efficient Drive
The semi-enclosed housing effectively blocks dust and oil mist while maintaining the efficient drive of
the PU synchronous belt (efficiency exceeding 95%). With a maximum speed of 3 m/s, it is suitable for
high-speed reciprocating motion.
Precise Positioning and Modular Expansion
Repeatability of ±0.05 mm is achieved, and multi-axis combinations (such as XY gantries and cantilever
configurations) are supported, allowing for flexible integration into automated production lines.
Industrial-Grade Durability
The aluminum alloy body features an anti-corrosion coating, and the guide rails utilize standard 20 mm
linear guides (externally mounted). The lifespan exceeds 5000 hours and is suitable for operating in
environments ranging from -20°C to 80°C.
Low-Cost Maintenance
The self-lubricating design reduces maintenance frequency, and the modular structure simplifies
installation and maintenance, resulting in excellent cost-effectiveness over long-term use.
