The 7055 slide is part of the new ULTIO range, designed for enhanced corrosion protection, particularly the rigorous demands for emergency vehicles. ULTIO slides are manufactured from high quality zinc plated C45 steel sections: Cold drawn inner beams with a rolled steel outer beam to allow a narrow space profile, demanded by fire truck manufacturers. Stainless steel grade 304 bearings and cages increase corrosion resistance, without compromising load or torsional rigidity.
The grade of steel profile is important in achieving accurate, strong ball races, which allow a slight pre-load without lateral play between the beams. This quality of movement is usually associated with high end hardened steel slides at substantially higher price points. Load rating at 600mm at full extension is 430kg per extended pair with huge safety margins to allow for vehicular shock & vibration.
The 7055 slide is identical to the 7050 except with an over extension of 120%. This is a special feature designed to completely extract pump and generator carriers from emergency vehicles and facilitate a four-man lift. All fixing points and beams remain as per the 7050, there is a reduction in the ball cage length to accommodate the extra travel. Load rating at 600mm is 387kg per extended pair. Ultio 7055 slide weighs 9kg per metre.
The 7055 slide is tested at 10,000 operational cycles, with the slides spaced 1000mm apart. At 550mm length, with 660mm extension and SWL loading of 378kg, the slides deflect 22mm. Deflection is the measurement of drop taken at the full extension of the slides and influences the ease of operational forces to close and open the drawer. At 378kg loading the operational forces are 20-25kg. During testing, the drawer was stable without any side load movement or damage to the raceways, due to the high grade of steel used in the construction of the beams. We do not recommend increasing the load capacity of this slide beyond what is stated.
