Fully Enclosed High Precision Ball Screw Module FSKSW-136 is an industrial-grade linear drive
component designed for precision positioning in harsh environments. It achieves excellent stability and
service life through a fully enclosed structure and high-grade ball screw technology. Its core features are
as follows:
Structural design Fully enclosed protection: The stainless steel shell integrates a double-lip seal to
effectively block dust, liquid and chemical corrosion, with a protection level of IP54/IP65, suitable for
high-demand scenarios such as dust-free workshops.
Modular integration: The compact body (silver/black optional) supports direct or indirect motor
installation (right/left/folding down), which is convenient for rapid deployment and maintenance.
Performance parameters High-precision transmission: Adopts C5-grade ground ball screw (optional C7
rolled screw), with a repeatability accuracy of ≤±0.01 mm, and is compatible with servo motors to
achieve high-speed motion (up to 6000 min⁻¹).
Strong load capacity: radial load up to 800 N, lateral load 500 N, anti-flipping torque 25 N·m, meet the
needs of heavy equipment handling.
Low friction and efficient operation: four-row ball circulation design with 45° contact angle, friction
coefficient as low as 0.003~0.005, energy consumption reduced by more than 30%.
Application scenarios
Widely used in CNC machine tool precision feeding systems, semiconductor wafer transfer equipment,
medical testing instruments and automated assembly lines, especially in the electronic manufacturing
links that require dust and moisture resistance.
Precautions for use
Avoid operating in explosive environments or at supercritical speeds, and regularly check the wear of
seals;
Long-stroke applications require controlled acceleration to reduce inertial impact and ensure rigid
support of the guide rails
The core advantages of the fully enclosed, high-precision ball screw module FSKSW-136 are reflected in
the following technical features:
Ultra-precision Motion Performance
A four-row steel ball design with a 45° contact angle achieves repeatable positioning accuracy of
±0.003mm, a rolling friction coefficient as low as 0.002, and preload technology completely eliminates
backlash. A closed-loop feedback system compensates for thermal deformation in real time, ensuring
consistent positioning accuracy throughout the 136mm travel range.
Industrial-grade, fully enclosed protection
The stainless steel housing achieves IP65 protection, and the built-in labyrinth seal and self-lubricating
system provide over 2,000 hours of salt spray corrosion resistance. Non-contact signal transmission
eliminates mechanical wear and reduces failure rates by 70% compared to open structures.
High-rigidity Structural Design
The Meehanite cast iron base and preloaded ball tracks combine to provide a dynamic load capacity
of 136kg and withstand instantaneous shock loads of 400N·m. Integrated heat sinks control
temperature rise to within ±2°C, supporting a wide operating temperature range of -20°C to 80°C.
Modular Integration and Expansion
The 136mm standard width supports multi-axis parallel connection, and pre-installed interfaces are
compatible with mainstream servo systems, increasing installation efficiency by 60%. AI algorithms
automatically optimize motion trajectories, reducing idle travel by over 15%.
Intelligent Maintenance System
The spindle condition monitoring system achieves 10,000 hours of trouble-free operation, and the
self-lubricating guideway maintenance cycle is extended by three times. Digital twin technology
enables predictive maintenance, reducing downtime by 40%.
