VJ

Product catalog summary

Technical Specifications:
Compact cylinders are designed for use with compressed, filtered air. They function within a temperature range of 0 to 60°C and a pressure range of 1 to 7 bar, with a maximum service pressure of 9.5 bar. Bore sizes range from 12mm to 100mm, and stroke lengths vary from 5mm to 150mm depending on the bore size.

Types of Cylinders:
- Double Acting (VJDA): Standard type, available with or without sensors.
- Single Acting (VJSR/VJSE): Includes spring return or spring extended types.
- Double Ended (VJDD): Double acting with adjustable stroke options.
- Adjustable Stroke (VJAT/VJAR): Available in retraction type.

Ordering Information:
The ordering code specifies type, bore size, rod end type, and stroke sensor options. For example, VJDA-32-50-B-S indicates a double acting cylinder with a 32mm bore, 50mm stroke, male thread rod end, and with a sensor.

Performance Parameters:
- Piston Speed: Ranges from 50 to 500 mm/sec for double acting and 50 to 350 mm/sec for single acting cylinders.
- Cylinder Thrust: Varies based on bore size and air pressure, with detailed thrust values provided for both push and pull actions.

Construction Materials:
- Head Cover, Body, Piston, and End Cover: Made from aluminum alloy.
- Piston Rod: Steel with hard chrome plating.
- Packing and Bearings: Made from Teflon, nitrile, and polyurethane materials.

Design Considerations:
An additional 5mm should be added to the overall cylinder length for certain configurations. Detailed dimensions and specifications for each cylinder type, including connection ports and thread types, are provided.

Notes:
The provided data is for reference only, and actual performance may vary due to frictional forces and mechanical efficiency.
