CHQ/CHDQ

Product catalog summary

Specifications:
The Series CHQ Compact Hydraulic Cylinder operates at a nominal pressure of 3.5 MPa with bore sizes from 20 mm to 100 mm. It is designed for double-acting action with a single rod and supports various mounting styles. It is compatible with standard mineral hydraulic fluid but not with water/glycol or phosphate fluids.

Standard Strokes:
Standard strokes are available in 5 mm increments, with specific ranges for each bore size. Bore sizes 20 mm to 40 mm offer strokes from 5 mm to 100 mm, while larger sizes extend up to 100 mm.

Auto Switch Options:
The cylinder can be equipped with built-in magnets for auto switch compatibility. Various models, including solid-state and reed switches, are available with different lead wire lengths and electrical entry types. Water-resistant types require consultation with SMC.

Construction and Materials:
The cylinder uses aluminum alloy for the rod and head covers, stainless or carbon steel for the piston rod, and NBR for seals. A seal kit is available for maintenance.

Mounting and Precautions:
Mounting requires hexagon socket head cap screws, avoiding lateral loads on the piston rod. The interlocking length of the rod end thread should be at least 80% of the thread diameter. Initial operation should involve air release and gradual pressure increase. Specific torque values are provided for mounting bolts.

Performance and Output:
The theoretical output is based on pressure and piston area, with tables for different bore sizes and pressures. The cylinder's mass varies with stroke length and bore size, with additional mass for male thread types.

Overview:
This document provides instructions on mounting and installing auto switches for Compact Hydraulic Cylinder Series CH-QB/CH-QWB, including specifications for different auto switch models, mounting procedures, and applicable tools and components.

Specifications:

Auto switch models include D-M9, D-M9V, D-M9W, D-M9WV, D-M9AL, D-M9AVL, D-A9, and D-A9V.
Bore sizes range from ø20 to ø100 mm.
Auto switch mounting brackets are categorized into BQ-1 and BQ-2 types.

Mounting Procedures:

For ø32 to ø100 mm: Insert the square nut for BQ-2 into the mounting rail, fit the spacer and bracket arm, and secure with screws. Adjust the detecting position as needed.
For ø20 mm: Similar steps as above but using BQ-1 components. Ensure proper torque for screws (M2.5: 0.1 to 0.2 N·m, M3: 0.5 to 0.7 N·m).

Applicable Auto Switches:

Solid state models: D-M9N(V), D-M9P(V), D-M9B(V), D-M9NW(V), D-M9PW(V), D-M9BW(V), D-M9NA(V), D-M9PA(V), D-M9BA(V).
Reed models: D-A90(V), A93(V), A96(V).

Tools and Components:

Use a watchmaker’s screwdriver with a grip diameter of 5 to 6 mm for tightening screws.
Ensure correct torque settings for different screw types to avoid damage.

Recommendations:

Always confirm the detecting position before final tightening of screws.
Order additional components like stainless steel screw kits separately if needed.
