UtiliTrak is an ideal choice for running two systems in parallel, where one slide uses DualVee guide wheels and the other uses MadeWell® crowned rollers. Because precise parallelism is difficult to achieve, it is not uncommon for mounting surfaces to be slightly out of parallel. UtiliTrak's design compensates for mounting errors, and does not require absolute parallelism for accurate operation. The DualVee guide wheel carriage assembly and vee channel serves as the motion side, while the MadeWell crowned roller and open channel side allows for parallel misalignment.
UtiliTrak is offered in two basic series; SW Series steel guide wheels running on a hardened bearing steel channel for larger loads and smooth operation, and PW Series polymer guide wheels running on an anodized aluminum channel, which provides a more economical choice for lighter duty applications where highly smooth operation is not as critical. A third option, Stainless Steel Composite UtiliTrak, is ideal for higher loads where corrosion resistance is required.
Video Application Story
UtiliTrak linear guides are being used to lift and lower a gurney in and out of an ambulance with little physical effort by medical staff. How does it work? The gurney hooks to a carriage plate at each side of the stretcher (four slides, two on each side). Once locked in place, the system can lift or lower a patient weighing up to 600 lbs. This durable, smooth motion system will help lower the risk of on-the-job injuries and ensure patient safety.
SW Series UtiliTrak is ideal for medium to heavy duty transport applications, and offers high speeds, excellent load capacity, smooth antifriction operation, and debris tolerance.
PW Series UtiliTrak is a lightweight solution for light to medium duty transport applications, and offers the lowest installed cost in its class, corrosion resistance, low noise and wear resistance.
Stainless Steel Composite UtiliTrak
Stainless steel composite UtiliTrak is a great option for high load requirements where carbon steel cannot be used due to corrosion.
The two outside guide wheels are concentric, while the center wheel(s) are eccentric. Fit up is pre-set at the factory, but is easily adjusted by rotating the eccentrically mounted center guide wheels. This allows modification of running characteristics such as drag, breakaway force and running friction.
Each assembly includes a standard lubricator, which distributes a light coat of oil along the length of the channel during normal operation. Lubrication of the channel increases load, life and speed capacities.
Two types of bridge connection are available. The steel version is available in a variety of widths, and features mounting holes according to customer specifications. The aluminum version features MCS profile extrusions with T-slots for ease of mounting.
The UtiliTrak carriage brake system permits the carriage on any PW or SW series UtiliTrak to be manually locked at any user-selected position on the UtiliTrak rail. The brake system can be easily installed by the end user on existing UtiliTrak systems, or pre-assembled at the factory on new systems.
The brake system consists of a brake block, mounting hardware, and a threaded stud handle with an adjustable handle arm. The brake block is made from aluminum and is hard anodized for long-lasting life and increased holding force. The handle has a plastic arm and a black-anodized steel stud. The mounting hardware is made from stainless steel.
The brake block mounts to either end of the UtiliTrak carriage and has a pair of brake arms that straddle the UtiliTrak rail. Each carriage can accommodate two brake systems. The brake system is engaged by turning the handle arm clockwise, which causes the brake arms of the block to clamp the rail. Disengage the system by simply turning the handle arm counter-clockwise.
The angular position of the handle arm can be adjusted which permits the brake system to be more compact in applications where access to the handle arm is limited. It also permits the handle to be set at any desired positon without affecting the brake engagement status and amount of braking force.
