Import 304 Stainless Steel Sliding Door Track Roller — Buy in Bulk from Supplier in China

This sliding door track roller is manufactured from 304 austenitic stainless steel, an alloy containing 18% chromium and 8% nickel that provides resistance to atmospheric corrosion and chloride staining in both interior and exterior architectural applications. The assembly incorporates precision ball bearings to reduce rolling friction and enable smooth, low-noise operation under door weights typical of residential patio, commercial storefront, and light industrial sliding systems. The source description indicates compatibility with multiple sliding door systems and suitability for heavy-load conditions, though exact load ratings, bearing specifications, and dimensional ranges are not provided and must be confirmed with the supplier.

The 304 grade offers good formability for stamped or machined roller housings and brackets, with typical yield strength of 215 MPa and hardness of 92 HRB in the annealed condition. Ball bearing configurations in door rollers commonly use carbon steel or 440C stainless steel races with nylon or polyoxymethylene retainers, though the specific bearing grade, ABECikh tolerances, and seal type (ZZ, 2RS, or open) are not detailed. The roller diameter, axle diameter, and bracket mounting geometry determine fitment to aluminium, steel, or timber track profiles; standard industry diameters range from 19 mm to 50 mm for residential and commercial applications.

Target buyers include construction contractors, architectural hardware distributors, window and door system manufacturers, and facilities maintenance procurement for commercial buildings. The product serves residential sliding patio doors, retail storefront entrances, warehouse partition systems, and interior room dividers where corrosion resistance and low rolling resistance extend operational life. Trade terms, minimum order quantities, and lead times are not stated in the source data and should be confirmed directly with Taizhou Route Metal Products Co.Led.
