Product catalog summary

Overview: The document provides comprehensive technical specifications and guidelines for the Parallel Style Air Gripper Series MHZ, covering various models such as MHZ, MHF, MHL, MHR, MHK, MHS, MHC, MHT, MHY, MHW, and others. It includes details on material composition, repeatability, body options, and mounting flexibility.

Specifications: The grippers are constructed from martensitic stainless steel with a repeatability of ±0.01 mm. They are available in bore sizes ranging from 6 mm to 40 mm and offer options like basic type, end boss type, and dust cover. The design allows for axial, lateral, and vertical mounting, emphasizing a low profile and high mounting flexibility.

Model Variations: The series includes compact, standard, and long stroke models, with options for double acting and single acting (normally open/closed) actions. The document highlights body thickness and mass for various models, focusing on improved remounting accuracy and secure mounting with positioning dowel pin holes.

Gripping Force Calculation: A step-by-step procedure is provided for calculating the required gripping force, considering factors like workpiece mass, gripping point distance, and operating pressure. It recommends selecting a model with a gripping force 10 to 20 times the workpiece weight, with additional safety margins for high acceleration or impact forces.

Graphical Data: Graphs illustrate the effective gripping force for different models and pressures, both for external and internal gripping. These graphs show the relationship between gripping force, pressure, and gripping point distance, aiding in model selection based on specific application requirements.

Recommendations: The document advises selecting a gripping force significantly higher than the workpiece weight to ensure safety and reliability, with additional safety margins for dynamic applications.

Operational Guidelines: The air gripper should be operated within specified pressure ranges (0.2 MPa to 0.7 MPa) to avoid adverse effects on its lifespan. Detailed instructions are provided for confirming the gripping point for both internal and external grips.

Construction and Components: The document details the construction of the air grippers, including materials used for various components such as the body, piston, lever, and guide. It lists replacement parts and provides instructions for ordering and assembling components.

Dimensions and Mounting Options: Detailed dimensions for both standard and dust cover models are provided, along with mounting options such as side tapped and through-holes in the opening/closing direction. Information on finger options and applicable models for different piping port locations is included.

Key Considerations: The document emphasizes the importance of using the gripper with a dust cover in dusty environments and provides specifications for various body options and end boss types.

Porting Options: Different porting options are detailed, including axial ported with one-touch fitting for coaxial tubing, axial ported with M5 port, and side ported configurations. Each type has specific dimensions and fitting requirements.

Auto Switch Mounting: Guidelines for auto switch mounting are provided, noting that side mounting with through-holes is not possible when auto switches are used. Dimensions for auto switch mounting grooves and compatible auto switches are specified.

Fittings and Tubing: The document describes the use of branch tee and branch "Y" fittings for changing from coaxial to single tubing, specifying necessary fittings and tubing for different configurations.

Mounting Procedures: The air grippers can be mounted in three directions: axial, lateral, and perpendicular. Each mounting type has specific requirements for bolt sizes and tightening torques. The document emphasizes using the correct mounting brackets and adjusting the mounting position based on auto switch operating conditions.

Standards and Recommendations: It is recommended to use specified protrusion standards when mounting auto switches. Caution is advised regarding the anti-corrosiveness of the linear guide section, particularly in environments prone to condensation.

Precautions: Users are cautioned about the inferior anti-corrosiveness of martensitic stainless steel compared to austenitic stainless steel. The document advises ensuring that the bolt's screw-in depth does not exceed specified limits to prevent damage to the switch body.

Key Data from Tables: Tables provide critical data on bolt specifications, tightening torques, and screw-in depths for different models. For example, the MHZ2-6 model uses M2 x 0.4 bolts with a maximum tightening torque of 0.15 N•m and a screw-in depth of 4.5 mm.
