SFE5050 Ball Screw
SFE5050 Ball Screw
Product descriptions
The SFE5050 Ball Screw Assembly is a high-performance linear motion component engineered for industrial applications demanding the ultimate combination of heavy-load capacity and extreme travel velocity.
Part of the High-Lead series, this model features a unique "square" configuration, pairing a robust 50mm nominal shaft with a matching 50mm lead. This geometry facilitates massive linear displacement per revolution, enabling machinery to achieve travel speeds exceeding 100 meters/minute without over-stressing the drive system. Combining infinite rigidity with an aggressive lead, the SFE5050 is the definitive solution for large-scale automation, automotive assembly lines, and heavy-duty gantry systems where speed and stability are paramount.

Key Engineering Advantages
1.Unprecedented Linear Velocity (Up to 100 m/min)
The SFE5050 redefines high-speed electromechanical actuation. To achieve 50 m/min with a standard heavy-duty screw (10mm lead), the motor must reach 5,000 RPM-a speed that would induce catastrophic "whipping" on a 50mm shaft. The SFE5050 resolves this by utilizing an aggressive 50mm lead, achieving 50 m/min at just 1,000 RPM. At a safe 2,000 RPM, the system can reach linear speeds of 100 m/min, combining the high throughput of a conveyor belt with the rigidity and precision of a ball screw.
2.Long-Stroke Stability & Massive Load Capacity
High-speed screws are often limited to short stroke lengths due to critical speed constraints and shaft flexibility. The SFE5050 overcomes this with a robust 50mm solid core that acts as a rigid structural beam. This allows for extended travel lengths of 3 to 5 meters without the need for intermediate supports or rotating nut designs. Furthermore, by utilizing large load-bearing balls (typically 6.35mm/0.25" or larger), it maintains exceptional dynamic load ratings, making it fully capable of transporting massive industrial payloads such as automotive chassis, engine blocks, or heavy pallets.
