Provides linear motion along a shaft through recirculating ball tracks, machined from solid stock for consistent running accuracy. Bore diameter is 16.0 mm, outside diameter 26.0 mm, and net mass 0.047 kg. The design is sealed on all sides, protecting the raceways from dust and debris while retaining lubricant inside the housing. KB16-PP suits linear guiding applications where a shaft-mounted ball bushing must run smoothly under axial load with minimal play. The full sealing on both ends allows continuous sliding travel without frequent relubrication, and the machined construction gives tighter dimensional control than formed variants, supporting stable positioning accuracy along the shaft axis.
