4005.7040 (Telescopic Slide) - 7040 (100-250kg) ULTIO 150% Steel Beams. Stainless Balls & Cages

The 7040 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 250kg per extended pair, with a huge safety margins to allow for vehicular shock & vibration.

This slide is designed to extend 150% of the closed length, so the drawer completely leaves the fabrication and access can be made at the rear without over reaching. without lateral play between the beams. Ultio 7040 weighs 9.5kg per metre. Applications for this super extension slide are fire truck light portable pumps/generators, weapon handling, light rail battery rafts, robotics and rugged tool boxes on excavators.

The 7040 slide is tested at 10,000 operational cycles, with the slides spaced 1000mm apart. At 550mm length, with full extension and SWL loading of 255kg, the slides deflect 24mm. 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. Four beam 150% extension slides deflect approx 4% of their closed length under maximum loading due to the multiple beams; much less for part load. At this maximum load capacity the operational forces are still less than 5kg to open and close. 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.

The 7040 slide can be purchased online, for global delivery, by clicking this link to our web-shop. The 7040 is stocked across all key lengths up to 700mm. The newly launched XTSR-80 150% travel slide in the Professional Range covers all  lengths (and bespoke) from 300 to 1,600mm on fast production lead-times.
