With a diameter of 4.8 to 15.8 mm, miniature ball transfer units from Rodriguez are tiny in size but deliver top performance. They are the ideal choice for use in measuring instruments, lightweight construction, and compact motion tasks, for example in the automated production of mechatronic components. The miniature ball transfer units also prove their strength in compact conveyor modules in clean rooms and in miniature mechanics.
Minimal space requirements and low weight: for a long time, these conditions were primarily associated with robotics and semiconductor technology. However, there is now a trend toward miniaturization in many other industries as well. Products and solutions are expected to be extremely small and lightweight while delivering maximum performance. However, this is only possible if the components used are also “small.”
360° mobility for a wide range of applications
Miniature ball transfer units are particularly useful wherever compact dimensions, multidimensional mobility, and precise, gentle handling are required. They represent a simple, robust and economical solution for achieving freedom of movement without complex mechanics. Typical areas of application include conveyor and handling technology, assembly and testing equipment, medical and laboratory technology, electronics and semiconductor manufacturing as well as machine and fixture construction.
Robust ball transfer units in small format
Rodriguez offers mini ball transfer units from the manufacturer Alwayse – with a plastic load ball for mark-free and light applications if required, without a seal. “Rodriguez is one of the world’s largest suppliers of ball transport systems,” explains Jörg Schulden, Head of the Linear Technology Division. “Our range includes several hundred different ball transfer unit variants.”
Further miniature versions of various products can be found throughout the range. In addition to particularly compact linear guides, miniature ball screws are also available. In the rotary sector, miniature ball screw couplings offer maximum performance in the smallest of spaces, while thin-section bearings have made a name for themselves as slimline problem solvers. Based on these compact components, Rodriguez also develops customer-specific system solutions.
