SKU Y9C7M6U4
Heavy-duty sliding door rollers are constructed with cold-rolled steel housings and feature ball bearing wheels. These assemblies mount into a recessed cutout in the bottom of the door rail, following standard industry dimensions for recess depth and hole spacing. They are designed for use with both aluminum and steel tracks, though nylon-tired wheels are required for aluminum tracks to prevent galling and premature wear. Each roller assembly supports up to 75 lbs., so 2-units per door reliably handle doors weighing up to 150 lbs. The wheel options include all-steel or steel cores with nylon tires, offering flexibility based on track material and load requirements. Installation requires precise alignment with the rail’s recess and matching bolt pattern. Maintenance is minimal, limited to occasional cleaning and inspection of bearing function. These rollers suit residential and light commercial sliding patio and interior doors where smooth, long-term operation is essential. Compatibility depends on matching recess dimensions and mounting hole layout to the specific door rail system.
