HR 4x3x3 Ball Bearing Hinge 102x76mm SUS304 Stainless Steel 80kg Load

Product Overview

The HR 4x3x3 mm 102x76 stainless steel ball bearing hinge is constructed from SUS304 grade material for enhanced corrosion resistance and durability. Measuring 102 mm in height by 76 mm in width, this hinge is used in commercial and residential door assemblies where long-term reliability and smooth operation are required. Its ball bearing design supports a maximum load capacity of 80 kg when three hinges are installed per door leaf.

What sets this hinge apart is its ball bearing (łożyskowanie kulkowe) mechanism, which delivers measurable smoothness in door movement and reduces long-term wear compared to plain hinges. This substantially minimizes maintenance needs and operational disruptions for buyers managing large property portfolios or public-access environments. It is particularly recommended for procurement in hotel, commercial office, and institutional projects where door durability and ease of movement are critical.
