The Ball Bearing Wheel Assembly for Narrow 'H' Bars is designed for use in sliding glass door systems. This assembly features a steel housing and a steel roller, providing a functional component for service windows and display shelving. It is engineered to press-fit into D5610 Series 'H' Bars and is compatible with various competitive 'H' Bar profiles. The assembly is suitable for panels up to 15 square feet when using 1/4" material. Technical specifications include a housing width of 1/4", a wheel width of 3/16", a wheel diameter of 9/16", a housing height of 19/32", and a housing length of 3/4". This ball bearing wheel assembly facilitates smooth movement for glass panels in hospitality and display applications. The steel construction of the housing and the roller provides a stable base for the sliding mechanism. The concave shape of the roller is specifically designed to track along the guide rails of the 'H' bar system. This assembly is intended for use in environments where sliding glass panels are required for access or display, such as service windows in hospitality settings or retail display cases. The press-fit installation method allows for direct integration into the bar profile without the need for additional fasteners. This component is a standard replacement or original equipment part for compatible 'H' bar systems.
