6×20×4mm Nylon Pulley Wheel with Sealed Bearing

Ultra‑Slim Guide Roller for Tight Drawer Slides, Mini Cabinets & Compact Sliding Assemblies

When clearance is limited, a roller's width matters as much as its diameter. This 6×20×4mm nylon pulley wheel is designed for compact hardware where standard rollers feel oversized. With a 6mm bore and an ultra-slim 4mm profile, it fits neatly on 6mm shafts / M6 hardware and supports smooth travel in narrow tracks and small mechanisms.

Key Specifications

• Size (ID × OD × W): 6 × 20 × 4 mm
• Bore / shaft fit: 6mm (M6 / 6mm rod compatible)
• Wheel material: engineering nylon
• Core: sealed bearing (smooth, consistent rotation)

Design & Performance

A nylon running surface is a practical choice for small sliding systems because it stays quiet in contact and helps keep friction low during frequent open/close cycles. In typical indoor use, it also tolerates everyday humidity and light dust better than many entry-level plastics found in basic rollers.

At the center, the sealed bearing is used to keep rotation steady and low-resistance. The result is a cleaner glide with less drag, reducing the “hang-up” feeling that often appears when rollers are wide, misfit, or prone to contamination.

Typical Applications

Commonly used in compact builds such as:

• narrow drawers and mini cabinet slides
• RV and space-saving furniture hardware
• display cases, small sliding panels, and enclosures
• maker projects, prototypes, and 3D‑printed mechanisms
