FBG | FBR Flanged Single Nut - Type 1
FBG and FBR flanged single nuts are compact ball screw nut options designed for straightforward mounting, smooth linear motion, and reliable integration into precision motion assemblies.
Use this page to review Type 1 dimensions, mechanical drawing references, load ratings, CAD downloads, and part number construction.
FBG / FBR Flanged Single Nut Overview
Flanged Mounting
Integrated flange design supports direct mounting into compact linear motion assemblies.
Ground Option
FBG indicates a ground ball screw assembly option for higher precision requirements.
Rolled Option
FBR indicates a rolled ball screw assembly option when cost-effective motion is required.
Compact Motion
Available Type 1 configurations support smaller screw diameters and compact package sizes.

Selection Notes
Screw Diameter
Review screw diameter and lead together to match the required speed, thrust, and positioning needs.
Mounting Envelope
Use the L, L1, Df, F, X, PCD, and V dimensions to confirm fit within the mechanical design.
Load Ratings
Compare Ca and Coa ratings during early sizing and confirm final selection with application conditions.
