LHA series

Product catalog summary

Overview

This document details the technical specifications, performance data, internal structure, ordering information, and layout drawings for the LHA Series Linear Guide 2-Jaw Pneumatic Grippers. These grippers are engineered for high durability, precision, and high-speed applications.

Performance Data

Grip force varies by model (006AS, 01AS, 03AS, 04AS, 05AS, 06AS), air pressure (0.3, 0.5, 0.7 MPa), and external finger length.
Grip force increases with higher air pressure and decreases with longer external finger length.
Grip force during opening is approximately 1.3 times greater than during closing.
Example: LHA-06AS can achieve up to 350 N grip force at 0.7 MPa.

Internal Structure and Components

Constructed from aluminum, stainless steel, carbon steel, resin, and urethane sheet.
Key parts include body, piston, cylinder cover, arm, linear guide, master plate, cushion, fulcrum shaft, operating shaft, and locating pin.
Seals include piston seal, rod seal, cylinder seal, and magnets for operation.
Material choice varies by model; stainless steel is predominant except carbon steel in some models (e.g., 06AS).

Specifications

Working pressure range: 0.1 to 0.7 MPa (0.3 to 0.7 MPa for Normally Open (NO) and Normally Closed (NC) types).
Lubrication: Not required or turbine oil class 1 (ISOVG32).
Ambient temperature: 5 to 60 °C.
Total jaw stroke varies by model; options include normal and long stroke (L1 series).
Repeatability: ±0.01 mm.
Weight and internal volume depend on model and stroke length.

Ordering Information

Model designation includes size and stroke type: Normal (no symbol) or Long Stroke (L1).
Sensor options: Various non-contact reed switches (ET3, ET3L, ET2, ET2L, etc.) and contact switches, with 1 or 2 sensors.
Cover options: Rubber, Heat (Silicon Rubber), Oil (Fluororubber).
Operation types: Normally Open (NO), Normally Closed (NC), Extra-Smooth Sliding (U), Self-Centering (K), and cover variations (G, GT, GH).

Key Features

Integral linear guide ensures high rigidity, accuracy, and long service life.
Supports long external fingers for extended reach.
Optional extra-smooth sliding and centering accuracy of ±0.05 mm.
Available rubber covers and long stroke (L1) series enhance versatility.

Layout Drawings

Detailed dimensional drawings include air port positions (open and close), mounting holes, locating pin holes, and overall dimensions.
Dimensions cover depths (1.5 mm to 12 mm) and diameters (4 mm to 10 mm) for precise installation.
Drawings support CAD data access for integration and design planning.

Critical Notes and Recommendations

Grip force is sensitive to air pressure and finger length; select model and pressure accordingly.
Repeatability and centering accuracy are vital for precision handling.
Material selection impacts durability and environmental suitability.
Sensor and cover options enable customization for specific operational needs.
Use provided dimensional data and CAD files for accurate mounting and system integration.

Summary of Critical Parameters

Model	Grip Force (N)	Air Port Depth (mm)	Mount Hole Diameter (mm)	Notes
