CROSSED ROLLER SLIDES Crossed Roller Slides Precision Crossed Roller Slides High Precision Crossed Roller Slides SERIES CROSSED ROLLER SLIDES Del-Tron's new series of crossed roller slides, offer designers additional flexibility in their choice of ready to install components for precision linear transfer. Our crossed roller slides, when compared to our ball slide products of equal size, offer higher load carrying capacity and, when operating at high cycling rates or with shock and overhanging loads, improved performance. Most importantly, our crossed roller slides provide high accuracy, 0.0001″ per inch of travel, and repeatability, 0.0001″ , exceeding our precision ball slides. Although crossed roller slides cost more than equivalent size ball slides, their overall performance, especially in applications where heavy loads must be moved in compact assemblies, often justifies selection. Operation Crossed roller slides physically resemble ball slides except for the bearing design. Specifically, each slide is comprised of an aluminum carriage straddling an aluminum base. Using a bearing system containing cylindrical steel rollers, the carriage glides, almost friction free, over the base. The rollers, alternately crisscrossed with each other, move between a set of 4, partially flat, parallel, smooth rods on each side of the base. The rollers share a larger contact surface with the rods as compared to the point contact of steel balls. This bearing design allows crossed roller slides to carry larger loads and absorb greater load impacts than equivalent size ball slides. Crossed roller slides are not as naturally self-cleaning in operation as ball slides. In operating environments, with little or no protection against dust and when heavy loads are not a consideration, consider Del-Tron's ball slides. Wide Selection Del-Tron offers over 47 models of crossed roller slides. Load capacities range from 30 lb to 779 lb, with travel from 0.5″ to 12″ . Installation into your system is simple. Counterbored holes in the base permit quick attachment to your assembly. Components attach to the carriage in the existing threaded mounting holes. continued on next page

PRECISION CROSSED ROLLER SLIDES SERIES Del-Tron's Precision Series Crossed Roller Slides offer the designer an aluminum base and carriage with hardened stainless components for superior corrosion resistance and less chance of particulate contamination. Available in standard low profile mounting, the designer can choose a style of bearing and type of rolling element specifically to meet the needs of the most particular applications. Preload can be adjusted to change the friction and axial play characteristics therefore customizing the slide to its intended use. A new 5-inch wide cross...
