MY2H/HT Series Type High-Rigidity Precision Linear Guide Mechanical Joint Rodless Cylinders

• Fluid: Compressed Air (typically requiring clean, dry, and finely filtered air)
• Action: Double Acting
• Guide Type:
  • MY2H Series Type: High-rigidity single linear guide (typically ball bearing type)
  • MY2HT Series Type: Ultra-high rigidity dual linear guides or reinforced single linear guide (typically ball bearing type)
• Operating Pressure Range: E.g., 0.1 MPa to 0.7 MPa or 0.8 MPa (refer to specific product manual)
• Proof Pressure: E.g., 1.05 MPa or 1.2 MPa
• Ambient and Fluid Temperature: E.g., 0°C to +60°C (32°F to 140°F) (non-freezing); special variants may offer wider ranges.
• Lubrication: The linear guide component typically requires periodic lubrication according to manufacturer guidelines; the pneumatic drive section may be designed for non-lube operation.
• Magnetic Switch: Standard configuration usually includes a built-in magnet for various types of magnetic switches.

Performance Parameters:

• Piston Speed: Wide range, e.g., 50 to 500 mm/s or higher (actual speed depends on load, air supply, piping, and cushion settings).
• Cushioning:
  • Standard: Adjustable air cushion at both ends.
  • Optional: External hydraulic shock absorbers.
• Stroke Length Range:
  • Extensive range of standard strokes, e.g., from 50mm to 1000mm, 2000mm, or more.
  • Longer custom strokes may be available for certain models and bore sizes.

Construction & Mounting:

• Available Bore Sizes: The MY2H/HT series type typically covers a range from small-medium to medium-large bores, e.g., ø16mm, ø20mm, ø25mm, ø32mm, ø40mm (MY2H). The MY2HT type may focus more on ø25mm and above or offer larger bore options to match its high load characteristics.
• Port Thread Types: Vary with bore size, e.g., M5, G1/8, G1/4, G3/8, etc. (or Rc, NPT threads).
• Piping Options: Usually supports standard end-of-cylinder piping; some models might offer centralized piping options.
• Mounting Options: Flexible mounting is typically provided, such as top clamping plates or bottom-bolted mounting, with corresponding accessories.

Load & Precision (Core Value of MY2H/HT Series Type):

• Allowable Load & Moment:
  • The primary advantage of the MY2H/HT series type lies in its exceptionally high allowable load and moment capacities. Permissible static and dynamic loads (radial, axial) and allowable pitch (Ma), yaw (Mb), and roll (Mc) moments are significantly greater than those of basic or slide-bearing guided rodless cylinders. The MY2HT series type generally offers even higher figures in these respects. These precise values are absolutely critical for selection and must be rigorously checked against the manufacturer’s load charts, performance curves, and detailed calculation methods.
• Running Parallelism/Straightness: High-grade linear guides ensure extremely high running parallelism and straightness of the carriage.
• Repeat Positioning Accuracy: Offers very high repeat positioning accuracy, making it ideal for precision automation tasks.
• Table Deflection: Under rated loads and moments, table deflection is minimal, ensuring the precision of the operation or process.

Application & Selection Guidance

• The MY2H/HT series type rodless cylinders, with their outstanding rigidity, precision, and load capacity, are widely used in:
  • Precision assembly and testing equipment
  • Semiconductor and electronics manufacturing and handling
  • Robotic seventh-axis applications, gantry systems
  • Precision conveyance and positioning of heavy or overhung workpieces
  • High-speed, high-dynamic response pick-and-place units
  • Machine tool loading/unloading, tool changers, and other auxiliary devices
• Core Selection Criteria: Selection must be based on precise calculations of actual application loads (weight, center of gravity), motion parameters (speed, acceleration), and external forces/moments. Ensure that all allowable load and moment ratings for the chosen model provide an adequate safety margin.
• The high-precision linear guides require a high degree of flatness for the mounting surface. Installation must adhere to the manufacturer’s guidelines to fully realize their precision benefits.
• Appropriate selection of air cushioning adjustment or external hydraulic shock absorbers is crucial, based on operating speed, load mass, and desired stopping characteristics.
• Pay attention to the maintenance and lubrication schedule for the linear guides to ensure long-term high performance.

It is strongly recommended to thoroughly read and understand the manufacturer’s latest product catalogs, technical data sheets, and selection software during the selection process. For complex applications, consulting with the Bepto technical support engineers is advisable to ensure an accurate selection that fully leverages the superior capabilities of the MY2H/HT series type cylinders.
