XL 50-Tooth Timing Belt Pulley — Precision Drive Component for 11mm Wide XL Belts

When your motion-control build demands accurate, slip-free power transmission, a mismatched or worn pulley becomes the weakest link. Makers, CNC builders, and workshop engineers who rely on XL-pitch timing systems need a pulley that holds tight tolerances across every revolution. This XL 50-tooth timing belt pulley is engineered for exactly that — delivering consistent, backlash-free rotation in demanding DIY and light-industrial drive systems.

Each pulley is machined from aluminum alloy with a natural or anodized finish, featuring 50 teeth on the XL pitch profile (5.080 mm / 0.200 in pitch). The bore diameter ranges from 10 mm to 25 mm (0.39 in to 0.98 in) to suit a wide variety of shaft sizes. Two style options are available: with flanges (Mit Zähnen) to keep the belt tracked, or without flanges (Ohne Zähne) for open-ended drive configurations. Compatible belt width is 11 mm (approximately 0.43 in).

Typical use cases include CNC router X/Y-axis drives requiring precise positioning, 3D printer extruder and gantry belt systems, and custom conveyor or automation rigs where an XL 50-tooth timing pulley for 11mm belt provides reliable, repeatable motion at moderate speeds.

⚙️ Compatibility: Fits standard XL-pitch timing belts, 11 mm (0.43 in) wide. Bore options: 10 / 12 / 15 / 17 / 20 / 25 mm. Select your bore diameter and flange style above before adding to cart.

✅ Key Features of These XL 50-Tooth Timing Belt Pulleys

🔩 50-Tooth XL Profile

Standard XL pitch (5.080 mm / 0.200 in) ensures direct compatibility with off-the-shelf XL timing belts used in CNC and automation builds.

📏 6 Bore Size Options

Available in 10, 12, 15, 17, 20, and 25 mm bore diameters to match common motor and drive shaft sizes without custom machining.

🛡️ Flanged or Flangeless Style

Choose the flanged (Mit Zähnen) version for positive belt retention, or the flangeless (Ohne Zähne) version for flexible open-drive layouts.

⚖️ Lightweight Aluminum Construction

Aluminum alloy body keeps rotational inertia low — ideal for high-cycle applications like 3D printer gantries and servo-driven axes.

🎯 Consistent Tooth Geometry

Precisely formed tooth profile minimizes belt wear and maintains positional accuracy over extended run times in repetitive motion systems.

🔧 Drop-In Replacement Ready

Standard XL 50T dimensions allow direct substitution in existing drive assemblies — no custom adaptation required for most common setups.

❓ Frequently Asked Questions

Which belt profile does this pulley fit?

This pulley is designed for the XL (Extra Light) timing belt profile with a 5.080 mm (0.200 in) pitch. It is not compatible with T5, GT2, HTD, or other belt profiles. Always verify your belt pitch before ordering.

How do I choose the right bore diameter?

Measure your motor or drive shaft diameter with a caliper. Available bore sizes are 10, 12, 15, 17, 20, and 25 mm. Select the bore that matches your shaft — a bore that is too large will require a keyway or set-screw adapter, while one that is too small cannot be installed without machining.

What is the difference between the flanged and flangeless versions?

The flanged version (Mit Zähnen) includes side flanges that keep the timing belt centered on the pulley during operation — recommended for most CNC and 3D printer applications. The flangeless version (Ohne Zähne) omits the flanges, which suits open-ended drive configurations or systems where belt tracking is managed by other means.

Is this pulley strong enough for CNC router use?

Yes. The aluminum alloy construction provides sufficient strength for typical CNC router axis drives operating at moderate loads and speeds. For heavy-duty industrial applications with high torque or continuous high-speed operation, please contact us to confirm suitability.

Will this pulley corrode or oxidize over time?

Aluminum alloy naturally forms a thin oxide layer that provides basic corrosion resistance in dry indoor environments. For humid or outdoor applications, an anodized finish variant is recommended. Contact us to confirm finish availability for your chosen variant.

Can I use this pulley with a 10mm wide XL belt instead of 11mm?

This pulley is optimized for 11 mm wide XL timing belts. A 10 mm belt may run on the pulley but could have slightly reduced lateral support from the flanges. For best performance and belt life, use a belt width that matches the pulley specification.

How do I calculate the gear ratio when pairing this with another pulley?

Gear ratio = driven pulley teeth ÷ driver pulley teeth. For example, pairing this 50-tooth pulley as the driven gear with a 25-tooth driver pulley gives a 2:1 reduction ratio, halving speed and doubling torque at the output shaft.
