The Glass Door Pivot Hinge is a structural pivot hinge designed specifically for glass doors, used to support, position, and control the opening and closing of glass doors. Unlike traditional hinges, it supports the weight of the door body through upper and lower axes, making the opening and closing of glass doors more stable, quiet, and smooth. Model 43B1 is made of SUS304 or SUS316 stainless steel, combined with a high-strength aluminum alloy base to ensure that the product remains stable during long-term use.

High-Strength Structural Support

The Glass Door Pivot Hinge is constructed from a single piece of SUS304, SUS316, or AL stainless steel, with a thickness of 5mm and a load-bearing capacity of 180N. After 100,000 cycles of fatigue testing, the structure shows no signs of cracking or loosening. The internal support seat is anodized to a surface hardness of HV240, improving impact resistance by approximately 30% compared to ordinary stainless steel, ensuring long-term stability and safety.

Precision Rotating Hinge System

The rotating hinge utilizes a precision-ground stainless steel round rod with a core diameter of 20mm and a clearance of less than 0.03mm. The rotational resistance torque during opening and closing is controlled between 0.8–1.0N·m, ensuring smooth opening and closing of the glass door. After 100,000 cycles of testing, the core wear does not exceed 0.02mm, maintaining smooth opening and closing performance and a service life of over 8 years.

High Installation Precision

The Glass Door Pivot Hinge has an overall length of 103mm and a standardized hole spacing of 80mm, allowing for quick integration with standard glass door systems. Assembly deviation is controlled within ±0.5mm, ensuring precise installation and a tight door closure. The hinge and base feature concealed fastening, creating a cleaner overall appearance and enhancing the visual integrity of the space.

Quiet Opening and Closing Design

The hinge utilizes a nylon sound-isolating gasket and metal bearings to effectively reduce friction noise. Measured noise levels during opening and closing are less than 25 decibels, approximately 40% lower than traditional mechanical hinges.

Exquisite Surface Finish

The product undergoes three polishing and two brushing treatments, achieving a surface gloss of 60% while maintaining a delicate touch. The polished layer achieves a wear resistance of 5.6×10⁻⁵g/cm² and improves fingerprint resistance by approximately 25%. The satin finish effectively reduces light reflection, enhancing the overall high-end feel and making it ideal for modern, minimalist spaces.

Shower Partition Doors

This pivot hinge ensures smooth opening and closing for shower room glass doors. Its high load capacity ensures stable operation for 8–10mm thick glass doors without sagging. The hinge's waterproof construction effectively reduces water seepage, maintains a tight seal, and creates a cleaner, tidier shower space.

Office Glass Doors

The Glass Door Pivot Hinge can be used for conference room or office glass partition doors. The pivot structure enables bidirectional opening. Precise control of the opening and closing angles, with an error of less than ±1.5°, ensures a tight closure and enhances sound insulation. Its simple appearance blends seamlessly with modern office spaces, creating a strong overall effect.

Commercial Display Cabinets

When used on display cabinet glass doors, it offers flexible and stable rotation, capable of 90° or 180° opening and closing. The hinge's high-precision construction ensures the glass door remains balanced even under frequent operation, preventing misalignment. The polished surface enhances light reflection, creating a brighter display.

Hotel Bathroom Areas

When used in high-end hotel bathrooms, the Glass Door Pivot Hinge's corrosion-resistant properties ensure it remains rust-free even under long-term exposure to humid and hot environments. Its silent opening and closing mechanism allows for gentle door operation, reducing noise disturbance and providing guests with a quiet and comfortable experience.

Public Building Glass Doors

Suitable for high-traffic areas such as airports, shopping malls, and clubs, its strong mechanical stability allows it to withstand thousands of opening and closing cycles daily. The hinge's robust structure prevents deformation, and its wear-resistant, non-fading surface maintains its metallic texture and aesthetic appeal over time.

Regular Surface Cleaning

We recommend wiping the hinge surface with a neutral detergent weekly and wiping it dry with a dry cloth to prevent scale buildup. Regular cleaning effectively prevents the accumulation of corrosive substances, keeps the hinges looking new, and extends the life of the surface coating.

Lubrication and Hinge Maintenance

Apply 0.1–0.2g of silicone-based grease to the hinge every 12 months to ensure smooth opening and closing. After lubrication, wipe off excess grease with a dry cloth to prevent dust from adhering. This maintenance measure can reduce the coefficient of friction by 30%, minimizing metal wear.

Screw Tightness Check

Check the screws every 6 months and maintain the recommended tightening torque of 9 N·m. If slight misalignment is detected, readjust the hinges to ensure even force is applied to the door. This will effectively prevent tilting or loosening.

Moisture-Proof and Anti-Oxidation Treatment

In high-humidity environments, spray a moisture-proof and rust-proof agent regularly to form a protective film. A quarterly deep maintenance is recommended to effectively prevent metal surface oxidation and enhance hinge durability.

Clean Rotating Parts

Quarterly, inspect rotating parts for dust and foreign matter. Use compressed air to clean internal clearances if necessary. Keeping bearings and washers clean will extend the life of the shaft and maintain smooth and stable opening and closing.
