Industrial SWF-24W Slide Bush Flange Type NSMP

NB Corporation’s SWF-24W round-flange, double-wide slide bush is a compact linear bearing in the SWF family that uses six recirculating balls to deliver smooth motion with low friction. Designed for precise, repeatable travel in compact axes, its bore is 1.5000 in (38.100 mm), outer diameter 2.3750 in (60.325 mm), and overall length 3.0000 in (76.200 mm), making it well-suited to small-to-midscale automation or machine-tool applications. The six-ball circuits provide stable load distribution, and the round flange configuration offers flexible mounting options in sliding-bush assemblies. The bearing is explicitly described as a linear-motion mechanism utilizing recirculating-ball elements to achieve smooth motion and low friction, a key factor for consistent positioning in automated systems. For this variant, the dynamic load rating is about 323 N and the static rating about 530 N, with tight geometric tolerances such as eccentricity and perpendicularity around 0.0005 in, reflecting NB’s precision engineering in the SWF lineup. Related NB variants in the same family include SWF24GW and SWSF24, which denote stainless-steel-retainer or resin-retainer configurations, respectively, offering options for environment and maintenance needs.
