Door & Window Rollers & Bearings
Qingdao Gleam Hardwares supplies door and window rollers, bearing wheels, guide bearings and pulley assemblies for hardware importers, window and door fabricators, distributors and OEM projects. This category is the selection hub for buyers comparing a door and window roller manufacturer, supplier or factory source without mixing unlike products into one specification.
Start with the running surface and application: a polymer-coated bearing, a profiled guide bearing, a corrosion-resistant bearing, a complete sliding-door pulley or a compact sliding-window wheel. Common commercial dimensions can be reviewed, while non-standard diameters, groove profiles, hubs, shafts, housings and brackets can be developed from an approved drawing or physical sample.
For a comparable B2B quotation, send the application, rail or track section, finished wheel diameter and width, bore or shaft, groove geometry, material, load and duty, quantity, packing and destination. A bearing code identifies the core only; it does not define the finished roller or complete door/window assembly.

OEM Drawing and Sample Matching
Special requirements can include flat, concave, U-groove, V-groove, crowned or flanged running surfaces; single, tandem or multi-wheel layouts; polymer or metal outer rings; and custom studs, sleeves, hubs or housings. These are development routes, not a claim that every combination is stocked. Final material, tolerance, load, corrosion resistance and sample approval are confirmed for the quoted model.
