Hevi-Rail® combined bearings allow for several unique design applications and handling tasks within the industrial market. Jib cranes, lift units and warehouse handling systems make up a small percentage of the many different ways Hevi-Rail bearings are applied to improve factory performance and operation by streamlining assembly and eliminating machine shut downs.
Material Handling: Other linear guide products rely on precise parallel alignment to reliably handle linear motion tasks; such as material handling, lifting and adjustment. This requires the installer to conduct a thorough and painstaking checking and re-checking of the monorails to ensure maximum parallelism. Apart from the time spent checking parallelism and realigning, this is also a very costly process. The linear guides also need to be preloaded beforehand for assured system rigidity; however, when dealing with large loads, the preload causes fretting and catastrophic failure in ball-type linear guides and complete stalling in plain bearing products due to exceeding moment load. With Hevi-Rail®, the unique combined bearing design allows the bearings to float within the rail, thereby eliminating the need for precise alignment and effectively reducing installation time.
Telescopic Applications: For high load telescopic handling, Hevi-Rail can support cantilevered loads up to 700 lbs. (318 Kg) extending out 90
