Overview

Flanged shaft couplings connect a shaft to a mounting face. The clamp body splits at the bore so a single hex socket screw locks the shaft, and the flange bolts to the mounting surface. Round, square, and compact flange shapes are available, in standard and long-sleeve series.

Available Sizes and Options

Model, material, and surface treatment options are listed in the first table; bore sizes and mounting dimensions for the standard and long-sleeve series are in the dimension tables. Custom versions are quoted from your drawing under our OEM/ODM service.
