Del-Tron Announces Its Smallest Ball Slide Assembly Ever



Del-Tron Precision has announced the new C-.5 linear ball slide assembly, its smallest ball slide ever. The new C-.5 is only 0.52 inches long, 0.25 inches high, 0.38 inches wide and offers a travel of 0.33 inches while providing a 0.75 pound load capacity, making it ideal for applications with the tightest envelope restrictions. Yet the new ball slide assembly maintains the high accuracy - such as 0.005 inch per inch of travel runout - low friction and stiction characteristics of other Del-Tron ball slide assemblies. The C-.5 is available in two weeks leadtime at only $79 each discounts for larger quantities.

The new C-.5 ball slide assembly consists of a lightweight aluminum base and carriage containing two rows of precision ball bearings separated by an engineering plastic retainer, rolling between four hardened and ground steel shafts on each side. Standard mounting holes are included in both the base and carriage for easy installation with only two fasteners. Its adaptable slide design allows the C-.5 to be adapted to the designer's subassembly, eliminating the need for additional components and reducing design time and tolerance buildup.

Straight-line design offers the lowest coefficient of friction because the rolling elements are separated from each other and they are not required to turn corners or to describe an oval path as they do in recirculating designs. The balls run exactly equal distances on a pair of tracks, permitting them to run virtually without friction, wear or skidding at any preload. The typical coefficient of friction is only 0.003.

Straight-line design also allows the manipulation of preload - an important capability that is increasingly needed in modern industrial equipment design. A tool steel gib is used internally on the side of the bearing to uniformly load all the rolling elements in the bearing and reduce looseness or play. A row of staggered set screws accessible from the side of the assembly allows the preload to be set and adjusted.

Del-Tron Precision began operations in 1974 supplying original equipment manufacturers with the world's first commercially available subminiature ball slide. Since then, thousands of Del-Tron ball slides have been incorporated into medical analyzing and testing machines, semiconductor processing equipment, computer peripherals, assembly systems, scientific instruments and many other machines. Del-Tron's modern corporate campus boasts highly automated computer controlled equipment and final inspection of 100% of all products has been Del-Tron's policy since its inception.
