Nippon Bearing – General Catalog No.179E

This general catalog brings together NB’s complete portfolio—slide bushings, slide guides, ball splines, actuators, shafts and ancillary components—so engineers can move from concept to part number without jumping between documents. Navigation is structured by product family and then by bore size, preload and accuracy grade, with clear cross‑references to compatible shafts, housings and accessories.

Each section provides dimensional drawings with tolerances, load ratings and life equations in the same view. Selection notes call out shaft hardness and surface finish requirements, recommended fits, and options for corrosion protection. The part‑numbering system is explained step by step, minimizing ambiguity when placing orders or creating BOMs.

Application examples—pick‑and‑place modules, inspection stages, packaging axes—help translate catalog data into practical limits on speed, acceleration and duty cycle. Where trade‑offs exist (stiffness vs. friction, preload vs. heat), the catalog summarizes them with simple rules of thumb.

Installation guidance covers datum selection, alignment of parallel rails, tightening sequences and verification methods. Implemented correctly, systems start up quickly, operate quietly and maintain accuracy over long intervals, reducing corrective maintenance.
