Sliding Door Pulleys
Sliding door pulleys include the wheel, bearing and—when required—the housing, carriage, bracket or adjustment mechanism. B2B buyers also search for sliding door rollers, sliding glass door rollers, patio door rollers, door roller assemblies, sliding door pulley wheels, tandem door rollers, adjustable door rollers and replacement roller carriages.
Qingdao Gleam Hardwares supplies and develops door roller components for importers, hardware distributors, fabricators and OEM programmes. A wardrobe, patio, shower, screen, cabinet, garage or commercial sliding door may use a very different envelope and track. These application names are useful starting points, but the original sample or assembly drawing determines compatibility.
Common commercial dimensions and special requirements can be reviewed. Send the door type, sash or panel weight, number of rollers, wheel diameter and width, groove, bearing or bore, housing dimensions, adjustment direction, fixing holes, track section, material, quantity and packing.

Wheel Materials and Custom Development
Running surfaces may be metal, POM, nylon/PA, PU or another approved construction. Groove shapes may be flat, U, V, concave, crowned or custom. Do not select a material from colour alone. Confirm the rail, load, noise target, corrosion requirement and service environment.
