Hevi-Rail Linear Bearings Keeps Cargo Accessible and Organized

June 23, 2011 - Rockford, IL  -  Posted by Zach Olson

Shipping containers face a constant struggle to optimize storage space and accessibility within a confined area. Organization of stored material is also important for accurate inventory and streamlined loading/unloading. To create an improved solution to container storage, PBC Linear collaborated with a leading designer in storage containment. The task was straightforward: design a racking system that maximized organization and storage for cargo.  PBC Linear recommended implementing their high load capacity Hevi-Rail® linear bearing solution installed in a specially designed assembly.


In the past, storage containers were filled by piling materials on top of each other; lacking any sense of organization. Finding a specific part within the filled container was extremely tedious, as was organizing and unloading materials after they had been knocked around for a week while travelling to their destination. The design team set out to solve this problem by designing internal framing to store materials and maintain organization for the duration of the shipment. After this was completed, they began to seek out quality linear motion components that could be manually operated and endure the containment load and environment.Hevi Rail Linear Bearings in Telescopic Racking


PBC Linear’s Hevi-Rail® extreme load tolerating linear bearings were the answer. Hevi-Rail components thrive in tough applications under extreme loads. Composed of hardened steel and designed to provide even dispersion of forces, Hevi-Rail linear bearings tolerate axial and radial loads up to 60 tons! For this application, Hevi-Rail components (bearing and profile rail) were installed into the shipping container framing to facilitate manually operated telescopic extension of the racking system. This ensured quick loading/unloading of material and increased access to all stored pieces. Also, due to the design of the Hevi-Rail bearings, the linear guide system did not require as much alignment and pre-load adjustment. This is because Hevi-Rail bearings float along their I-channel rails – reducing the cost over competing products that would need to be specifically pre-loaded for the particular application.


Once Hevi-Rail® was installed into the container’s framework, the robust internal racking system could easily be extracted/retracted for up to 2.3 m (90’’) under 318 Kg (700 lb) cantilevered loads. This drastically improved loading/unloading and allowed personnel to have quick access to the materials they needed. Also, if the outer container shell is damaged, the racking design can be transferred into another container without re-sizing. Perfect for long-term storage of a wide array of materials, this racking assembly is the reliable method for organized shipment.
