This set provides ten pieces of mini threeinone planar thrust ball bearings designed for compact axial load support in small mechanisms. The bearings are optimized for precise, lowfriction operation in tight spaces and offer a versatile range of sizes to fit multiple applications. The package highlights the F1223M size with a known dimension of 12x23x7.5 mm, illustrating the scale and potential fit for compact assemblies. Key benefits Versatile multisize set for flexible use across projects, reducing the need to source individual bearings. Compact, lowprofile form suitable for tight spaces where axial load bearing is required. Threeinone planar thrust ball bearing configuration provides axial load support with a simple, compact layout. Designed for smooth operation and reliable performance in small mechanisms and hobbyist or lightindustrial applications. Readytouse kit that supports rapid prototyping and iterative design work.

Use cases and applications Small CNC or 3D printer assemblies: use as a compact axial bearing in Zaxis or linear actuator assemblies where space is limited. Robotics and hobby projects: provide reliable axial support for miniature joints or sliding platforms in lightweight robots and animatronics. Model making and precision equipment: suitable for miniature mechanisms that require stable axial load handling with minimal play. Care and handling guidance Handle bearings with clean tools to avoid introducing contaminants. When integrating into an assembly, ensure clear seating within the mating parts and verify axial alignment. If lubrication is required by your design, apply an appropriate lubricant compatible with the bearing material and operating conditions, following supplier recommendations. Note Material details are not provided in the listing; confirm material and finish with the supplier or product datasheet before finalizing an installation or application. For exact fit, verify shaft and housing dimensions against the corresponding Fsize designations to ensure proper clearance and seating.
