The 7050 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.
Applications for the 7050 slides are military and rescue vehicle drawers, machine guarding, train battery boxes and door systems. Ultio 7050 slide weighs 9kg per metre.
The 7050 slide is tested at 20,000 operational cycles, with the slides spaced 1000mm apart. At 550mm length, with full extension and SWL loading of 420kg, the slides deflect 12mm. Tested to 500kg loading on 1,000 cycles, the deflection increases to 14mm. 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 420kg loading the operational forces are less than 15kg. At 500kg loading this increases to 25-30kg. During both tests, 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.
