R63-10T6-FSI

The Hiwin R63-10T6-FSI ball screw is a precision rolled ball screw designed for high-load and high-accuracy linear motion applications. Here's a breakdown of what each part of the model number typically means:

🔍 Model Breakdown: R63-10T6-FSI

Part

Meaning

R - Rolled or Ground type screw (Hiwin uses "R" for rolled and ground; actual type depends on spec sheet—this one is likely ground).

63 - Nominal screw shaft diameter = 63 mm

10 - Lead (distance the nut moves in one revolution) = 10 mm

T6 - Number of ball circuits = 6 circuits (enhanced load capacity and stability)

FSI - Flange Single Nut, Internal ball return (FSI = Flange Single Internal)

✅ Key Features

• Diameter: 63 mm

• Lead: 10 mm (good balance between speed and force)

• Nut Type: FSI — Flanged single nut with internal circulation

• Precision: Typically C5 or higher (verify from spec sheet)

• Preload: Optional depending on application (Z0, Z1, Z2 classes available)

• Applications: CNC machinery, injection moulding, machine tools, and other automation systems

📈 Performance Considerations

• High load capacity due to multiple ball circuits

• Smooth motion and low backlash

• Can be preloaded for zero-backlash performance

• Compatible with standard support units (BK, FK types)

📘 Recommendation

To ensure compatibility and performance, always confirm:

• Ball nut dimensions

• Threaded and machined ends (customization may be required)

• Support unit selection (e.g., FK25, BK25, etc., depending on screw end machining)
