APPLICATION & DESIGN EXAMPLE -
HORIZONTAL CANTILEVERED SYSTEM
A horizontal cantilevered system can be used in a range of applications and is particularly useful when space is at a premium. Typical applications include a "pull out" on the side of a vehicle (to create extra space internally) and racking systems, where something needs pack away after use.
In its simplest form, you need just 2 rails & 4 bearings. Here 6 bearings are shown - the front 2 bearings add stength to the system when it is packed away. By adding further rails & bearings, you can make a telescopic cantilever which can extend to twice its original size. There are further application examples showing two stage and three stage telescopic systems.
The main advantage of Combined Roller Bearings over other track rolling systems is that the smaller axial rollers contact the web of the profiled rails. This helps to keep the system running parallel and consequently prevents the system from jamming.
The bearings can be supplied pre-welded to a mounting plate and then simply bolted onto the carriage (above diagram), or they can be welded directly to the structure for a more compact arrangement.
For ultra heavy systems, see our Jumbo combined roller bearings.
