Product catalog summary

Overview

The BHE Series Self-Centering Hand is a pneumatic 2-jaw gripper designed for precise handling with high accuracy and durability. It features self-centering capability with ±0.05 mm accuracy and adjustable opening and closing strokes as optional features.

Key Features

Self-centering accuracy: ±0.05 mm
High rigidity and durability due to hard stainless steel construction
Adjustable opening and closing stroke options available
Reliable performance suitable for precise handling tasks

Models and Specifications

The series includes models BHE-01AS, BHE-03AS, BHE-04AS, BHE-05AS, and BHE-06AS, differing mainly in size, grip force, and weight.

Model	Working Pressure (MPa)	Ambient Temperature (°C)	Total Jaw Stroke (mm)	Cylinder Diameter (mm)	Rod Diameter (mm)	Repeatability (mm)	Centering Accuracy (mm)	Weight (g)
BHE-01AS	0.2 to 0.7	5 to 60	14	20	10	±0.01	±0.05	260
BHE-03AS	0.2 to 0.7	5 to 60	16	25	12	±0.01	±0.05	438
BHE-04AS	0.2 to 0.7	5 to 60	22	32	16	±0.01	±0.05	1040
BHE-05AS	0.2 to 0.7	5 to 60	20	25	12	±0.01	±0.05	438
BHE-06AS	0.2 to 0.7	5 to 60	22	32	16	±0.01	±0.05	1040

Note: Centering accuracy and repeatability may degrade if the jaw is overloaded.

Grip Force Performance

Grip force varies with air pressure and external finger length. The graphs indicate grip force for opening and closing at pressures of 0.3, 0.5, and 0.7 MPa across different finger lengths for each model:

BHE-01AS: Grip force ranges approximately 15N to 30N.
BHE-03AS: Optimal grip force between 30N to 50N.
BHE-04AS: Optimal grip force between 40N to 80N.
BHE-05AS: Optimal grip force between 80N to 150N.
BHE-06AS: Optimal grip force between 100N to 250N.

Parts and Materials

The gripper consists of multiple components made from aluminum, stainless steel, bearing steel, and resin. Key parts include:

Body and Cylinder: Aluminum or Stainless Steel depending on model
Master (Base) Jaw and Piston: Stainless Steel
Seals: Various piston, rod, and cylinder seals specified by model
Bearings: Cross roller bearings and bearing steel shafts
Magnets: Half moon shape magnets for sensor operation

Lubrication and Operating Conditions

Working pressure range: 0.2 to 0.7 MPa
Lubrication: Not required or use Turbine Oil Class 1 (ISOVG32)
Ambient temperature range: 5 to 60 °C

Sensor and Options

Models can be ordered with non-contact reed switch sensors for position detection. Sensor options include:

ET3 and ET3L: Non-contact 3-lead sensors
ET2 and ET2L: Non-contact 2-lead sensors
Quantity options: 1 or 2 sensors

Adjustable stroke options are available for opening, closing, or both strokes.

Layout and Installation

Detailed layout drawings and CAD data are available for each model to assist with installation and integration. Effective depths and air port dimensions vary by model and option.

Recommendations and Limitations

Do not overload jaws to maintain centering accuracy and repeatability.
Use appropriate air pressure within specified range for optimal grip force.
Consider lubrication requirements based on operating environment.

Summary

The BHE Series Self-Centering Hand offers a robust, precise pneumatic gripper solution with customizable stroke adjustments and sensor options. It is suitable for applications requiring high accuracy and reliable gripping force across a range of sizes and force capacities.
