The AXCR-S series uses a one-piece ring design at constant overall height (one-piece rings at constant overall height); both rings can be bolt-fastened. The overall height H is constant across all sizes at 25.4 mm (SSA design), which distinguishes this series from the AXCR-U series. The series comprises 6 sizes: AXCR 130-S through AXCR 360-S.

2) Please enquire at sales@eb-system.com in case of high speed applications.
3) Measuring speed nconst = 5 rpm; values depend on the selected preload and lubrication.
4) Measured on the installed bearing with ideal adjacent construction. PRR50 is the restricted runout accuracy option and can be specified when ordering.
