The smallest PRT-04 slewing ring igus® makes. The micro version of the PRT-04 was developed for confined installation spaces where every other PRT in the lineup is too large, and pairs lightweight aluminum rings with wear-resistant iglide® J sliding elements to deliver smooth, grease-free dry operation in a footprint scaled for instruments, gimbals, and miniaturized assemblies. Tightest tolerances in the product line. Fully maintenance-free.
When to use it: Ultra-compact rotary applications where the standard PRT-04 footprint is too large.
When not to use it: When standard or compact PRT-04 dimensions fit without compromise (those variants offer better load capacity and broader accessory support), or when manual hand-positioning needs the consistent tactile feel that only the preloaded micro variant delivers.
Application areas: Optical instruments, scientific equipment, sensor gimbals, miniaturized robotics, medical devices, hand-held tools, and any precision rotary mechanism where overall size has to be measured in millimeters.
