Product catalog summary

Overview

This document provides detailed technical specifications, parts information, performance data, and ordering instructions for the HK Series Cross Roller Parallel 2-Jaw Pneumatic Grippers. These grippers are designed for high accuracy, smooth operation, and durability in industrial automation applications.

1. Specifications

Models Covered: HK-32MS, HK-40MS, HK-50AS1, HK-63AS1, HK-80AS
Working Pressure: 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 Range: 5 to 60 °C
Jaw Stroke, Cylinder & Rod Diameters, Internal Volume, Repeatability, and Weight: Vary by model, e.g., HK-32MS has 24 mm jaw stroke, 32 mm cylinder diameter, 16 mm rod diameter, 25.3 cm³ internal volume, ±0.01 mm repeatability, and 1.36 kg weight.

2. Key Features

High accuracy and smooth motion enabled by cross roller bearings in sliding components.
Compact and rigid body design with telescopic slides and bearing retainers for high moment-to-size ratio.
Optional protective rubber covers for harsh or dusty environments to prevent ingress of chips, dust, and mist.
Optional oil-resistant sensors (fluororubber or silicon rubber covers) available for certain models (HK-50AS1, HK-63AS1, HK-80AS).
Model number updates: Some MS models have been renamed to AS1.

3. Sensor and Option Details

Sensor types include contact 2-lead and non-contact reed switches with 2 or 3 leads.
Options include rubber cover (G), oil-resistant cover (GH), and heat-resistant cover (GT).
Sensor quantity options: 1 sensor (S1) or 2 sensors (S2).
Mounting brackets required for some models and sensor types, except HK-50AS1, HK-63AS1, and HK-80AS.

4. Parts and Materials

Detailed parts list includes body, cylinder, cylinder cover, piston, arm, master jaw, bearing guide, cushion, side cover, seals, shafts, springs, magnets, and rollers.
Materials used include aluminum, carbon steel, stainless steel, resin, and high-carbon chromium bearing steel.
Specific parts vary by model; for example, aluminum is used for 50AS1 and 63AS1 parts.

5. Performance Data

Grip force varies by model and air pressure, with graphs showing grip force versus external finger length for opening and closing actions.
Optimal grip force ranges by model:
- HK-32MS: 200N to 350N
- HK-40MS: 350N to 600N
- HK-50AS1: 500N to 800N
- HK-63AS1: 800N to 1400N
- HK-80AS: 2000N to 3000N
Grip force is influenced by air pressure (0.3, 0.5, 0.7 MPa) and finger length.

6. Installation and Layout

Mounting hole dimensions and depths are specified for each model, including air port locations for open and close states.
Locating holes and mount hole depths vary by model, with detailed layout drawings referenced (e.g., 120P to 124P).
CAD data is available for precise design integration.

7. Ordering Information

Model number format includes size, sensor type, sensor quantity, and options (e.g., HK-32MS-ET3-S2-G).
Symbols and codes for sensors and options are provided for accurate ordering.
Notes clarify model number changes and sensor compatibility.

Critical Information and Best Practices

Ensure correct working pressure range is maintained for reliable operation.
Use lubrication as specified or not at all to avoid damage.
Select appropriate sensor and cover options based on environmental conditions.
Refer to layout drawings and CAD data for installation to ensure proper fit and function.
Note model number changes to avoid ordering errors.

This summary captures the essential technical data, features, and usage guidelines for the HK Series Cross Roller Parallel 2-Jaw Pneumatic Grippers, facilitating informed selection, installation, and maintenance.
