2000 pcsCustom PA6 Nylon U-Groove Guide Roller with 6x19x6mm Bearing for Sliding Doors
⚙️Product Description:
This U-Groove Pulley Wheel is specifically engineered for applications demanding low noise, lightweight, and wear-resistant performance. It perfectly integrates a high-strength PA6 Nylon (Polyamide 6) housing with a pre-installed 626ZZ deep groove ball bearing.
The PA6 Nylon Housing: The nylon material offers exceptional impact resistance, self-lubricating properties, and corrosion resistance, making it ideal for humid environments or frequent cycling applications. The U-groove design provides precise guidance for wire ropes, cables, or round tracks, ensuring smooth, non-jerky movement.
The Built-in 626ZZ Bearing: The 626ZZ bearing (6mm ID, 19mm OD, 6mm Width) utilizes double metal shields (ZZ) to effectively block dust ingress, maintaining the roller's low friction and high rotational accuracy over time.

| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
