Industrial NB SMA 20GWUU Slide Bushing

NB SMA20GWUU Slide Bushing is a block-series sliding bearing element from Nippon Bearing (NB), designed as part of the SMA-W standard block double-form family for compact linear guidance. It uses the rolling motion of balls to provide smooth, low-friction linear motion in tight assemblies, and features a 20 mm bore (inner contact diameter) compatible with NB SMA-W blocks to create a compact two-piece slide unit. This part belongs to NB’s SMA slide-bush lineup, described in NB catalogs as a standard 20 mm bore option within the SMA family, with mounting geometry that supports secure alignment and load distribution when paired with the corresponding SMA-W blocks. The SMA20GWUU designation identifies the bore size and block configuration within the SMA lineup, enabling straightforward interoperability with other SMA-W components in automation equipment and other compact linear-motion applications.
