The T8 Lead Screw (also known as TR8) is specifically designed to convert the rotational motion of a stepper motor into precise, quick, and accurate linear motion. Its trapezoidal thread profile offers an ideal balance between high torque transfer and rapid movement speed. When paired with its corresponding T-type flanged nut, it guarantees a balanced force distribution, minimizing backlash and wear during continuous operation.
Ensure integration with your machine's stepper motors and guide rails by reviewing the data below.
Item | Specification |
Model Name | TR8 / T8 Trapezoidal Lead Screw |
Screw Diameter (ID) | 8 mm |
Length Options | 300 mm / 350 mm (Custom lengths up to 2000mm available) |
Pitch | 2 mm (distance between individual threads) |
Lead | 8 mm (linear travel per one full 360° revolution) |
Starts | 4-Start thread design |
Screw Material | High-quality 304 Stainless Steel |
Nut Material | Brass / Copper (High wear resistance) |
Our T8 lead screws are manufactured for strict tolerances required in B2B machinery production:
Dependable precision: The uniform thread geometry ensures accurate dimensional growth for every turn of the stepper motor, which is critical for consistent 3D printing layer heights.
Long-life durability: Constructed from 304 stainless steel, the spindle is highly resistant to corrosion, rust, and high temperatures, yielding a very long usage span.
Smooth & low friction: Polished trapezoidal threads coupled with a self-lubricating brass nut deliver ultra-smooth sliding with very low friction coefficients.
This 8 mm screw is the industry standard for lightweight, precise automated positioning systems:
3D Printers: Primarily used for the Z-axis lift mechanism on RepRap, Prusa, and custom-built 3D printers.
CNC Machines: Ideal for desktop CNC routers, laser engravers, and prototyping applications.
Automation: Camera sliders, positioning actuators, and automated inspection systems.
We provide end-to-end manufacturing and supply chain solutions tailored to machine builders and regional distributors.
OEM customization: If you require custom thread leads (e.g., Tr8x2, Tr8x4), specialized anti-backlash POM nuts, or specific end-machining based on your technical drawings, our factory can accommodate your requests.
Lead Time: Fast manufacturing with normal delivery between 3 to 15 days.
Payment Terms: 100% L/C at sight, 30% T/T deposit (70% against B/L or L/C), Western Union, and PayPal supported.
Q1: What is the difference between "Pitch" and "Lead" on this T8 screw?
A: "Pitch" refers to the distance between two adjacent threads (2 mm). "Lead" is the total linear distance the nut travels along the screw in one complete 360° rotation. Because this is a 4-start screw, the Lead is 8 mm (4 starts × 2 mm pitch = 8 mm travel per revolution).
Q2: Can I get a different type of nut instead of standard brass?
A: Yes. While standard brass/copper nuts are provided, we can supply anti-backlash nuts or custom POM (plastic) nuts based on your requirements to eliminate clearance issues.
Q3: Are the ends of the screw machined for bearings/couplers?
A: Standard stock comes uncut/unmachined at the ends. If you require standard end-machining to fit into KP08 pillow blocks or motor couplings, please provide your technical drawing with your inquiry.
