YZXQ :: Linear Guides & Rails

EGH Series Low-Profile Linear Guide Blocks

Low assembly-height blocks with CA tapped-hole and SA through-bolt mounting.

EGH Series Low-Profile Linear Guide Blocks — EGH-CA / EGH-SA manufactured by YZXQEGH-CA / EGH-SA

Overview

EGH blocks keep the assembly height low while retaining four-row Gothic-arch ball contact, so machine builders can shorten the stack above the rail without losing rigidity. EGH…CA blocks are mounted with screws from above; EGH…SA blocks use through-bolts from the top face. Sizes cover 15 mm to 30 mm rail widths on EGR rails cut to length and drilled to the standard pitch.

Key Features

  • Low assembly height for compact stacks
  • CA tapped-hole and SA through-bolt mounting
  • Four-row ball contact in all directions
  • Rail widths from 15 mm to 30 mm
