Heavy-duty sliding door roller assemblies with POK Wheels for doors. Designed for smooth movement, stable support, and easy height adjustment. The POK wheels run on ball bearings for low friction and quiet operation.
Each unit includes a metal carriage that fits into the bottom door profile, with an adjustment screw for precise door alignment. Single, tandem, and multi-wheel options are available, and customization is supported.
What Is a POK Sliding Door Roller?
A POK sliding door roller uses polyketone (POK) engineering plastic for the wheel. It offers good wear resistance, impact strength, and stable performance for frequent sliding use.
Compared with metal wheels, POK wheels help reduce direct metal-to-track contact, resulting in smoother and quieter movement when properly matched with the rail system.
