This product is a multi size AXK bearing kit designed for flexible installation in AXK series linear motion systems. It includes one piece each of the following components: AXK5578, AXK6085, AXK6590, AXK7095, AXK75110, AXK80105, 85110, 90120, 100135, plus a 2AS needle roller thrust bearing and two washers (AXK90120). Key benefits Versatile selection: encompasses multiple AXK sizes in a single kit, enabling quick matching to different axis requirements without sourcing separately. Improved motion performance: the inclusion of a 2AS needle roller thrust bearing provides axial load support to enhance stability and smoothness in linear motion. Alignment and spacing support: two washers (AXK90120) help ensure proper spacing and alignment for reliable operation. Downtime reduction: having several common AXK sizes together speeds maintenance, repairs, or upgrades on machines with AXK linear guides. Key attributes Functionality: AXK series compatible bearing components with needle roller thrust bearing and spacers for axial alignment. Compatibility: designed to work with AXK linear bearing configurations and related hardware in standard AXK installations. Contents: one piece each of AXK5578, AXK6085, AXK6590, AXK7095, AXK75110, AXK80105, 85110, 90120, 100135; plus a 2AS needle roller thrust bearing and two AXK90120 washers. Performance: intended to provide reliable, precise linear motion with options to suit different axis loads and clearances. Applications and use cases Rebuilding or upgrading a multiaxis CNC machine where several AXK sizes are needed to match different axis requirements. Servicing automated production line linear axes that use AXK bearings, allowing quick replacement with matching components. Upgrading a small automation project, such as a robotic arm or precision slider, where compact AXK bearings and a needle roller thrust bearing improve load handling and motion quality. Maintenance and handling guidance Inspect components for signs of wear or damage before installation. Clean and inspect mating rails and housings prior to assembly to ensure proper seating. Use appropriate mounting hardware and correct spacing with the included washers to maintain axial alignment. Store the kit in a clean, dry environment to prevent corrosion or contamination. This description reflects the included components and their intended use within AXK series linear bearing applications, maintaining alignment with the product's brand, model references, and features.
