Sliding Door Pulley — Double Row Ball Bearing Roller for Wardrobe, Closet & Glass Partition Doors

Single-row pulleys on heavy wardrobe and glass partition doors wear unevenly, causing the door to tilt, drag, or jump off track. This sliding door pulley uses a double-row ball bearing design that distributes the panel load across two rows of bearings—reducing wear, extending service life, and keeping the door running level and smooth.

Available in two wheelbase sizes—12 mm (25 mm wide housing) and 15 mm (27 mm wide housing)—with cam wheel and concave wheel profiles, and with or without a top wheel. All variants feature a nickel-plated housing for corrosion resistance. Select the wheelbase, wheel profile, and top wheel configuration that matches your existing track and door hardware.

Use them on wardrobe and closet sliding doors, bathroom glass partition doors, furniture sliding panels, or any interior sliding door system that requires a double-row bearing roller for heavier or more frequently used panels.

✅ Compatible with 12 mm wheelbase (25 mm wide) and 15 mm wheelbase (27 mm wide) sliding door tracks — cam and concave wheel profiles — with or without top wheel configurations

✅ Key Features of This Sliding Door Pulley

⚪ Double Row Ball Bearing: Two rows of ball bearings distribute the door panel load evenly across the wheel—reduces bearing wear, prevents tilting under load, and maintains smooth rolling performance over time.
🔩 Nickel-Plated Housing: Nickel plating on the bearing housing resists rust and corrosion in humid environments—suitable for bathroom glass partitions and kitchen sliding doors as well as standard wardrobe applications.
🔳 Cam & Concave Wheel Profiles: Cam wheels suit flat-bottom track channels; concave wheels engage V-groove or rounded tracks. Select the profile that matches your existing track cross-section for correct engagement and stable rolling.
📐 Two Wheelbase Sizes: 12 mm wheelbase (25 mm wide housing) for standard wardrobe and furniture tracks; 15 mm wheelbase (27 mm wide housing) for wider track channels and heavier door panels.
🔧 With or Without Top Wheel: Top wheel variants include an upper guide wheel that engages the top track channel—prevents the door panel from swinging out at the top. Order without top wheel if your system uses a separate upper guide or has no top track.
💪 Carbon Steel Load-Bearing Structure: Carbon steel internal components handle the weight of heavier wardrobe and glass partition panels without deforming under sustained load.

🎯 Who Is This For?

🛌 Wardrobe & Closet Sliding Doors

Replacing worn single-row pulleys on wardrobe sliding doors—the double-row bearing handles the weight of full-height wardrobe panels and maintains smooth operation through years of daily use.

🚿 Bathroom Glass Partition Doors

Glass partition doors in bathrooms and wet rooms need corrosion-resistant hardware—the nickel-plated housing resists moisture and cleaning chemical exposure in high-humidity environments.

🛋️ Furniture & Interior Sliding Panels

Fitting or replacing pulleys on furniture sliding panels, room dividers, or interior glass doors where a compact double-row bearing roller is needed for smooth, stable operation.

❓ Frequently Asked Questions

How do I choose between the 12 mm and 15 mm wheelbase options?

Measure the width of the track channel your existing pulley runs in. The 12 mm wheelbase (25 mm wide housing) suits standard wardrobe and furniture sliding door tracks. The 15 mm wheelbase (27 mm wide housing) is for wider track channels and heavier door panels. If unsure, remove the existing pulley and measure its wheelbase—the distance between the two bearing rows—before ordering.

What is the difference between cam wheels and concave wheels?

Cam wheels have a flat or slightly convex rolling surface suited to flat-bottom track channels. Concave wheels have a V-shaped or curved groove that engages a rounded or V-groove track rail. Match the wheel profile to your track cross-section—using the wrong profile will cause the pulley to ride incorrectly on the track and wear prematurely.

Do I need the top wheel variant or the one without?

If your sliding door system has a top track channel that the door panel engages at the top, choose the variant with a top wheel—it prevents the panel from swinging out at the top during sliding. If your system uses a separate upper guide rail or has no top track engagement, choose the variant without a top wheel.

Why use a double-row bearing instead of a single-row?

Double-row ball bearings distribute the door panel load across two rows of bearing balls instead of one. This reduces the load per ball, slows bearing wear, and keeps the door running level under heavier loads. For wardrobe and glass partition doors that are opened and closed many times daily, double-row bearings provide significantly longer service life than single-row alternatives.

Is the nickel-plated housing suitable for bathroom use?

Yes. Nickel plating provides corrosion resistance in humid environments and resists the mild cleaning chemicals commonly used in bathrooms. It is suitable for glass partition doors in wet rooms and bathrooms. Avoid prolonged exposure to strong acids or bleach-based cleaners, which can degrade the plating over time.

How do I install the pulley?

Remove the door panel from the track. Locate the existing pulley housing at the bottom of the panel and unscrew the mounting hardware. Remove the old pulley and position the new one in the same location. Tighten the included copper nut components to secure the pulley to the panel. Reinstall the panel in the track and test the slide. Adjust the pulley height if the panel does not sit level in the track.
