MXL Timing Belt Pulleys — Precision 2.032mm Pitch Drive Components for Robotics & Automation

When your motion system demands repeatable, slip-free power transfer, a mismatched or worn pulley becomes the weakest link in the chain. Engineers and makers building CNC routers, 3D printers, robotic arms, and small-batch automation rigs need MXL timing belt pulleys that hold tight tolerances across thousands of cycles — without backlash or belt skip. These MXL-type step synchronous pulleys are designed for exactly that workload.

Each pulley is machined to the MXL tooth profile with a 2.032 mm (0.080 in) pitch and a 7 mm (0.276 in) belt-contact width. The stepped hub design accepts bores ranging from 3 mm to 16 mm (0.118 in – 0.630 in), covering the most common motor shaft sizes in the MXL drive class. Two hub configurations are available: K-type (standard through-bore with set-screw flat) and BF-type (flanged bore for axial retention). Tooth counts span MXL14T through MXL100T, letting you dial in the exact gear ratio your application requires.

Typical use cases include stepper-motor drive trains in desktop CNC machines requiring low-backlash MXL pulley sets, servo-axis timing systems in pick-and-place robotics where consistent pitch engagement is critical, and lightweight conveyor or indexing mechanisms in small-batch manufacturing that rely on synchronous belt-and-pulley drive systems.

⚙️ Compatibility: Fits standard MXL open-end and closed-loop timing belts with 2.032 mm pitch and 7 mm width. Verify bore diameter and tooth count against your motor shaft and drive ratio before ordering.

✅ Key Features of These MXL Timing Belt Pulleys

📐

MXL 2.032 mm Pitch

Conforms to the MXL tooth standard for direct interchangeability with any MXL-profile timing belt, ensuring consistent pitch engagement and zero-slip synchronous drive.

🔩

Wide Bore Range: 3 – 16 mm

Available in 3, 3.175, 4, 5, 6, 6.35, 8, 10, 12, 12.7, 14, 15, and 16 mm bores to match the most common stepper and servo motor shaft diameters used in robotics and CNC builds.

🔄

K-type & BF-type Hub Options

K-type offers a clean through-bore with set-screw flat for secure shaft locking. BF-type adds a flange for axial belt retention, reducing the risk of belt walk on unsupported spans.

🦷

14T – 100T Tooth Count Selection

An extensive tooth-count range from MXL14T to MXL100T lets you configure drive ratios from near 1:1 to 7:1 within a single pulley family, without switching belt profiles.

📏

7 mm Belt-Width Step Design

The stepped synchronous wheel body keeps the 7 mm belt centered and aligned, reducing edge wear and extending belt service life in continuous-duty applications.

🏭

Machined for Dimensional Consistency

Each pulley is machined to consistent tooth-profile tolerances, supporting repeatable positioning accuracy in stepper-driven axes and servo-feedback loops.

❓ Frequently Asked Questions

How do I choose the right tooth count for my application?

Select tooth counts based on your required drive ratio. Divide the driven pulley tooth count by the driving pulley tooth count to get the ratio. For example, a 30T driver paired with a 60T driven pulley gives a 2:1 reduction. This range covers MXL14T through MXL100T, supporting ratios from near 1:1 up to approximately 7:1 within the same belt profile.

What is the difference between K-type and BF-type hubs?

K-type pulleys feature a standard through-bore with a set-screw flat on the hub, allowing the pulley to be locked onto a shaft using a grub screw. BF-type pulleys add a flange on one or both sides of the belt contact surface, which helps retain the belt laterally and prevents it from walking off the pulley during operation — particularly useful on unsupported or long belt spans.

Which bore size should I select for my motor shaft?

Measure your motor shaft diameter precisely before ordering. Common stepper motor shafts are 5 mm, 6.35 mm (1/4 in), and 8 mm. Servo motors often use 6 mm, 8 mm, or 10 mm shafts. Select the bore that matches your shaft diameter exactly — a bore that is too large will cause runout and positioning errors even with a set screw installed.

Are these pulleys compatible with standard MXL timing belts?

Yes. These pulleys conform to the MXL tooth profile standard with a 2.032 mm pitch. They are compatible with any MXL open-end or closed-loop timing belt with a 7 mm width. Ensure the belt width matches the 7 mm pulley face width for proper engagement and to avoid edge loading.

How strong are these pulleys for continuous-duty use?

MXL-profile pulleys in this size class are designed for light-to-medium duty synchronous drive applications such as 3D printers, desktop CNC machines, and small robotic axes. They are not rated for high-torque industrial conveyor or heavy-load applications. For continuous-duty use, ensure your belt tension, speed, and torque load remain within the MXL belt system's rated capacity for the tooth count and width selected.

Can I use these pulleys in a corrosive or outdoor environment?

The corrosion resistance of these pulleys depends on the material and finish of the specific variant. If your application involves moisture, chemicals, or outdoor exposure, contact us to confirm the material specification before ordering. For corrosive environments, consider pairing with a stainless or anodized variant where available.

What is the pitch diameter for a given tooth count?

For MXL pulleys, the pitch diameter is calculated as: Pitch Diameter = (Number of Teeth × Pitch) ÷ π. For example, an MXL20T pulley has a pitch diameter of (20 × 2.032) ÷ 3.1416 ≈ 12.94 mm. Use this to calculate center-to-center distance and belt length for your drive layout.
