Module 5 Steel Spur Gear Pinion — 40mm Face Width for CNC & 3D Drive Systems

When your CNC router, 3D printer, or custom motion rig demands a gear that won't flex under load, undersized teeth or thin face widths become the weak link. This Module 5 steel spur gear pinion is engineered for makers and machine builders who need a robust, drop-in drive component with a generous 40mm (≈1.57 in) face width and a full range of tooth counts from 10 to 30 teeth.

Machined from structural steel, each pinion features a Module 5 tooth profile — meaning a 5 mm pitch diameter per tooth — with a face width of 40mm and pitch diameters ranging from 50mm (10T) to 130mm (26T) depending on the selected variant. Bore diameter and keyway dimensions vary by tooth count; see variant options for exact bore specs.

Typical applications include CNC rack-and-pinion axis drives, large-format 3D printer gantry systems, rotary indexing tables, robotic arm joints, and custom automation prototypes where a standard Module 5 mesh is required.

⚙️ Meshes with any standard Module 5 spur gear, rack, or mating pinion. Verify bore diameter and keyway against your shaft before ordering.

✅ Key Features of These Module 5 Steel Spur Gear Pinions

🔩
Module 5 Tooth Profile

5 mm pitch per tooth for smooth, low-backlash mesh with any standard Mod 5 mating gear or rack.

📏
40mm Face Width

Wide 40mm (≈1.57 in) face distributes load across more tooth contact area, reducing wear and deflection.

🔧
Structural Steel Construction

Machined from steel for high tensile strength and durability in continuous-duty drive applications.

📐
10–30 Tooth Range

17 tooth-count variants let you dial in the exact gear ratio your drive system requires without custom machining.

🏭
CNC & 3D Printer Ready

Dimensionally consistent tooth geometry suits rack-and-pinion CNC axes, extruder geartrains, and rotary stages.

🔄
Standard Mod 5 Interchangeability

Fully interchangeable with any ISO/DIN Module 5 gear in your existing drivetrain — no custom tooling needed.

❓ Frequently Asked Questions

What does "Module 5" mean for this gear?
Module (Mod) is the ratio of pitch diameter to tooth count. A Module 5 gear has 5mm of pitch diameter per tooth — so a 20-tooth Mod 5 gear has a 100mm pitch diameter. Only other Module 5 gears or racks are compatible.
Which tooth count should I choose for my CNC rack-and-pinion axis?
For most CNC router rack-and-pinion drives, 20–25 teeth (100–125mm pitch diameter) is a common starting point, balancing speed and torque. Fewer teeth give higher torque and lower speed; more teeth give higher speed and lower torque.
Is this gear compatible with a standard Module 5 rack?
Yes. Any standard ISO/DIN Module 5 rack with a 20° pressure angle will mesh correctly with these pinions. Verify the rack face width is at least 40mm to ensure full tooth engagement.
What is the bore diameter and how do I mount it to my shaft?
Bore diameter and keyway dimensions vary by tooth count. Please refer to the variant options or contact us to confirm the bore spec for your selected tooth count before ordering.
Can this gear handle continuous-duty CNC operation?
Yes. The steel construction and 40mm face width are suited for continuous-duty rack-and-pinion CNC drives at moderate loads. For very high-speed or high-torque applications, confirm the steel grade and surface hardness with us.
Does this pinion work with 3D printer extruder or Z-axis drives?
Module 5 is a relatively large pitch, more common in CNC and industrial drives than compact 3D printer extruders (which typically use Mod 1–2). It is well-suited for large-format 3D printer gantry drives and Z-axis gearboxes.
Are all tooth count variants in stock?
All listed variants (10–26 teeth) show in-stock availability. Select your required tooth count from the variant selector above to confirm current stock and pricing.
