Nippon Bearing – Slide Bush

NB slide bush linear bearings provide compact, low‑friction guidance on hardened shafts. The catalog covers closed, open and adjustable types, with single or double units, so designers can tailor rigidity and compliance to the application.

Tables list dimensions, recommended housing fits and permissible loads alongside guidance on shaft hardness and surface finish. Self‑aligning housings and support rails are explained for cases where the frame cannot guarantee perfect parallelism.

Sealing arrangements, relubrication grooves and stainless variants are cataloged for harsh or sanitary environments. For high‑cycle machinery, the text calls out how clearance and preload affect noise, heat and wear.

Mounting advice includes datum usage, clamping torque and inspection points to confirm smooth travel without stick‑slip, even after thermal stabilization.
