CU / CDU Series Free Mount Cylinder

SOLH CU/CDU rectangular free mount cylinder features ultra-thin block structure with multi-surface mounting holes, enabling multi-angle direct installation without brackets to save equipment space. Complete variants include non-magnetic CU, magnet-equipped CDU, CDUK non-rotating rod and CDUW double guided rod models. Bore sizes φ6~32mm, available in single/double acting types with fixed rubber buffers on both ends for continuous oil-free operation. CDU series is compatible with CMSH and DMSH magnetic switches for position detection and tolerates partial side load. Widely used in 3C & semiconductor jigs, automation stoppers, light clamping positioning and small press-fit mechanisms for compact automated equipment.

CU / CDU Series Free Mount Cylinder

Brand: SOLH by Richge Technology

Product Overview

     SOLH CU/CDU series rectangular block free mount cylinder. Multi-surface mounting holes enable direct installation in any orientation without brackets. Ultra-thin compact design widely used for light-load pushing, clamping and positioning in automation equipment with limited installation space.


Series Variants

Model
Feature
Application
CU
Without magnet ring, cannot fit magnetic switches
Cost-sensitive projects without position feedback
CDU
Built-in magnet, support CMSH/DMSH magnetic sensors
Need extend/retract position detection
CUK/CDUK
Non-rotating piston rod
Workpiece angle must be fixed, prevent shaft rotation
CUW/CDUW
Twin piston rod, integrated guide, anti-torsion
Applications with side load & offset force




Core Advantages

     -- Multi-direction mounting: Install from bottom, side or end face, save mounting bracket;

     -- Slim rectangular body, 40% thinner than standard tie rod cylinder;

     -- Multiple structures: standard single rod, anti-rotation rod, double guided rod;

     -- Built-in magnet version (CDU) with adjustable sensor slots;

     -- Self-lubricating bearing, oil-free continuous operation;

     -- Fixed rubber buffer pads to reduce impact and noise.
