Glass
AstraRoll provides advanced, heat-stabilized components engineered for the extreme thermal environments of the glass conveyor system and annealing lehrs. Meticulously designed for high-temperature resilience, our glass manufacturing rollers utilize specialized materials—including heat-resistant stainless steel, carbon fiber, and non-marking coatings—to ensure flawless surface quality for float glass and optical glass production. We prioritize thermal stability and low thermal expansion, delivering micron-level precision to prevent glass deformation or scratches during high-speed transport. Whether you are outfitting solar glass tempering lines, automotive glass fabrication, or bottle manufacturing facilities, our custom conveyor rollers provide the structural durability and non-stick performance required for your most critical high-heat applications.
What you may want to know about Glass
As a professional high‑precision high‑temperature‑resistant industrial roller manufacturer, AstraRoll specializes in premium glass conveyor rollers, glass tempering rollers and glass transport rollers, core functional components exclusively for glass deep‑processing production lines, including glass tempering furnaces, cutting machines, edging equipment, washing machines, laminated glass production and insulated glass assembly lines. Our glass‑grade rollers combine high‑temperature resistance, ultra‑smooth non‑scratch surface, dimensional stability and anti‑slip performance, ensuring safe, scratch‑free conveying, heating and processing of flat glass, tempered glass, ultra‑thin glass and architectural glass. They deliver stable performance under long‑term high‑temperature baking, high‑speed transmission and continuous heavy‑load operation.
Unlike ordinary industrial rollers, glass processing rollers must avoid scratching glass surfaces, withstand high‑temperature environments inside tempering furnaces, maintain low thermal expansion and keep precise concentricity at high temperatures. We adopt high‑strength seamless steel tubes, heat‑resistant alloy steel and lightweight aluminum alloy as roller substrates, paired with high‑temperature‑resistant silicone coating, ceramic coating, aramid fiber wrapping and precision mirror polishing. Strict control over roundness, straightness and surface smoothness prevents glass breakage, chipping or surface damage. We fully customize roller size, coating thickness, heat resistance grade, surface hardness and shaft‑end structure to match glass tempering, washing, edging and automated conveying processes.
Core Product Range
High‑Temperature Resistant Glass Tempering Rollers
Heat‑resistant alloy steel rollers wrapped with high‑temperature‑resistant aramid fiber or special‑formula silicone coating, stable at 600–750 °C inside tempering furnaces. No deformation, no sticking, widely used in horizontal glass tempering furnaces.
Soft‑Coated Glass Conveyor & Transport Rollers
High‑elasticity non‑marking silicone or PU coated rollers, scratch‑free and anti‑slip. Ideal for glass cutting, washing, edging, sorting and room‑temperature automated conveying lines.
Precision Mirror‑Polished Glass Transport Rollers
Ultra‑fine polished stainless steel or aluminum alloy rollers with smooth burr‑free surface, preventing scratches on ultra‑thin electronic glass and high‑end architectural glass.
Ceramic‑Coated High‑Durability Glass Rollers
Wear‑resistant ceramic‑sprayed rollers with excellent high‑temperature stability and long service life, suitable for heavy‑duty continuous glass tempering and high‑speed production lines.
Custom Special‑Purpose Glass Processing Rollers
Tailor‑made micro‑diameter precision rollers and large‑size heavy‑load rollers for ultra‑thin glass, automotive glass, photovoltaic glass and special‑shaped glass deep‑processing equipment.
Key Features & Product Advantages
Ultra‑Smooth Scratch‑Free Surface
High‑precision polishing and soft elastic coatings eliminate burrs, particles and sharp edges, protecting glass surfaces from scratches, indentations and chipping during conveying and processing.
Excellent High‑Temperature Resistance & Thermal Stability
Heat‑resistant substrates and high‑temperature coatings resist tempering furnace heat, with low thermal expansion to avoid bending and deformation at high working temperatures.
Anti‑Slip & Stable Glass Positioning
Elastic silicone/aramid coating increases friction coefficient, preventing glass sliding, shifting or warping during high‑speed transportation and thermal tempering.
High‑Precision Dimensional Consistency
Strict control over roundness, straightness and concentricity ensures even glass stress distribution, greatly reducing breakage rate in automated glass production lines.
Wear‑Resistant & Long Service Life
Wear‑resistant coating materials withstand long‑term repeated glass contact and friction, lowering replacement frequency and maintenance costs for glass factories.
Full Customization for Glass Production Lines
Customize roller diameter, length, coating material, heat resistance grade and mounting structure to match all mainstream glass tempering, washing and conveying equipment brands.
