5PCS Stainless Steel D‑Shaft Compatible for FTC/gobilda/rev Robotics/FRC/First/FLL/WRO/STEAM/VEX 3.9 x 0.2in

Description

Product Overview

The 5PCS Stainless Steel D‑Shaft set from EVTSCAN is engineered for precision robotics applications where strength, reliability, and ease of installation are paramount. Each shaft measures 3.9 × 0.2 in, offering a compact profile that fits seamlessly into a wide range of drive systems featuring a matching D‑bore. Constructed from high‑grade stainless steel, the shafts resist corrosion, wear, and deformation even under continuous load, ensuring long‑term performance in demanding environments. The D‑profile provides a flat surface for set screws, delivering a secure, non‑slip connection while preserving the outer geometry for smooth interaction with bearings and mating components. This set includes five identical shafts, allowing users to replace worn parts quickly or equip multiple mechanisms without additional inventory. The design balances rigidity with low friction, enabling effortless sliding and precise motion control across FTC, VEX, FRC, and other competition platforms.

Usage

These D‑shafts are ideal for a broad spectrum of robotics projects, from high‑school competition teams to professional research labs. In FTC and VEX builds, they serve as the central axle for gearboxes, winches, and linear actuators, where a secure set‑screw interface prevents slippage during rapid acceleration and deceleration. Hobbyists can integrate the shafts into custom 3‑D‑printed chassis or CNC‑machined frames, benefiting from the stainless steel’s durability and the D‑bore’s universal compatibility. The lightweight nature of the shafts simplifies handling and reduces overall robot mass, which is critical for achieving optimal speed and maneuverability. Additionally, the shafts perform reliably in educational settings, where repeated assembly and disassembly demand components that maintain tolerance and function over many cycles.
