SFU Threaded Low Friction Durable Ball Screw

SFU Type Ball Screw (Special for Replacing Taiwan TBI)

The SFU type ball screw is a high-precision transmission component specially designed to replace the same model of Taiwan TBI ball screws. It is fully compatible with the installation dimensions, performance parameters, and interface standards of the TBI SFU series. No modification to the equipment installation structure is required, enabling direct and seamless replacement. At the same time, it achieves upgraded optimization in precision stability, load-bearing capacity, and cost performance, and is widely applicable to various industrial scenarios requiring high-precision linear transmission, helping equipment maintain or even improve operational efficiency.

Core Product Advantages (Suitable for TBI Replacement with Superior Performance)

As a direct replacement for the Taiwan TBI SFU series, this product optimizes the pain points in industrial applications while inheriting the core functions of the original series, balancing compatibility and high performance. The core advantages are as follows:

● Complete Dimensional Compatibility, Seamless Replacement Without Pressure: Strictly following the standard dimensional specifications of the Taiwan TBI SFU series, key parameters such as screw outer diameter, lead, nut outer diameter, flange size, and shaft end machining precision are completely consistent with the same TBI models (e.g., SFU1605, SFU1610, SFU2005, etc.). The nut mounting holes and fixing methods are accurately matched. During replacement, there is no need to modify the equipment bracket, motor interface, or installation spacing. The replacement can be completed by directly disassembling the old part and installing the new part, which greatly reduces equipment modification costs and downtime.

● Upgraded Precision, More Accurate Positioning: Adopting a high-precision grinding/rolling process, the precision grades cover P3, P5, C5, C7, etc., which can be flexibly matched according to the precision requirements of the original TBI equipment. The variation over any 300mm length strictly complies with the corresponding precision standard, and a maximum fine feed of 0.1μm can be achieved. The positioning error is smaller than that of TBI products of the same precision, and the repeat positioning precision is more stable, which effectively improves the precision of equipment processing and transmission, making it suitable for scenarios with high precision requirements such as CNC machine tools and precision automation equipment.

● Optimized Load-Bearing and Rigidity, Stronger Durability: The screw is made of high-strength alloy materials such as SCM450 and S55C, and its hardness reaches HRC58°~62° after induction heat treatment. The nut is made of SCM415 material with carburizing heat treatment, and the steel balls are SUJ2 high-hardness balls. The dynamic rated load, static rated load, and rigidity all meet or exceed those of the same TBI models (for example, the dynamic rated load of SFU1605 can reach 1380kgf, the static rated load is 3052kgf, and the rigidity is 32kgf/µm). It can bear larger radial and axial loads, reduce deformation and wear during long-term operation, and its service life is 15% longer than that of TBI products.

● Low Resistance and Low Noise, More Stable Operation: Adopting an internal circulation design, the steel balls achieve stable circulation through a metal circulator, avoiding the friction noise of the external circulation structure. The operating noise is lower than that of the same TBI series products. At the same time, the driving torque is only 1/3 of that of traditional sliding screws, and the transmission efficiency is as high as 90% or more, which reduces motor energy consumption. There is no jamming or impact during operation, making it suitable for high-speed operation scenarios. The instantaneous speed can reach up to 4500rpm, and the conventional operating speed can reach 3000rpm.

● Strong Environmental Adaptability and Convenient Maintenance: It is suitable for a conventional working environment of -30℃~80℃ and can bear a maximum temperature of 110℃ for intermittent operation. Low-temperature environments can be accommodated through special deployment; the nut is equipped with an NBR dust ring, which has excellent sealing performance, effectively preventing dust and impurities from entering and reducing internal wear. At the same time, it supports separate delivery of the screw and nut, and the preload can be adjusted as needed. The maintenance cost is lower than that of TBI products, with sufficient supply and a shorter delivery cycle.

Replacement Advantages and Application Scenarios

Based on the above core product advantages, this product is completely consistent with the original TBI SFU series in terms of replacement convenience and application scenarios, and can be adapted to the original equipment without additional adjustments.
