625ZZ Y-Shaped Nylon Pulley – Door & Window Roller

Compact Guide Rollers for Drawer Slides, Cabinet Tracks, Small Doors & DIY Mechanisms — Multiple Sizes / Colors

Small sliding systems often fail for simple reasons: the roller is too bulky, the surface drags, or the bearing gets noisy after a short time. This pulley-wheel series is built for tight installations that still need reliable, smooth travel. Each wheel combines an engineering-nylon outer ring with a sealed bearing and a 5mm bore, making it an easy match for M5 bolts or 5mm shafts/rods in furniture hardware and light mechanical guides.

With several diameters and two neutral finishes (black and gray), you can choose the profile that fits your clearance, contact surface needs, and the look of your hardware—without changing the mounting size.

Specifications (Available Options)

All sizes are ID × OD × Width:

Color	Size	Typical Fit / Purpose
Black	5×25×7mm	Balanced size for compact drawers and small sliding panels
Black	5×29×8mm	More contact area for slightly heavier drawers/longer travel
Gray	5×24×7mm	Low-profile choice for narrow tracks and tight assemblies
Gray	5×23×7mm	Ultra-compact option when every millimeter matters

Common features across the series

• Bore: 5mm (M5 / 5mm shaft compatible)
• Wheel material: engineering nylon (quiet, track-friendly)
• Core: sealed bearing (consistent rotation, reduced contamination)

Performance Highlights

These wheels are designed to improve the feel of sliding motion in everyday hardware:

• Quiet rolling: nylon contact helps reduce rattle and harsh running noise.
• Low resistance: the nylon surface and bearing work together to keep movement light and smooth.
• Everyday durability: suitable for typical indoor conditions, including normal humidity and light dust exposure.
• Clean appearance: black blends into dark frames and hardware; gray suits lighter or neutral-colored builds.

Common Applications

A practical choice for:

• kitchen and bathroom drawers, vanity slides, and cabinet tracks
• small furniture sliding doors and panels
• light window/track hardware (non-heavy-duty)
• maker projects, enclosures, jigs, and small automation prototypes

Selection Guide

• Pick 5×23×7mm or 5×24×7mm when clearance is tight or the track is narrow.
• Pick 5×25×7mm as an all-around option for compact furniture slides.
• Pick 5×29×8mm when you want more stability and contact surface for medium drawers or longer runs.
