Technical Overview: DSNU-20-25-P-A Pneumatic Cylinder
The DSNU-20-25-P-A is a double-acting round cylinder designed to meet international standards like ISO 6432 and CETOP RP 52 P. It offers a 25 mm stroke length with a 20 mm piston diameter, ideal for medium-force linear motion applications. The piston rod uses a M8 male thread, and the cylinder can be easily mounted with optional accessories.
Cushioning is handled by elastic rings/plates at both ends, providing gentle deceleration and reducing shock loads during piston movement. With a working pressure range of 1 to 10 bar, this model delivers an advance stroke force of 188.5 N and a return stroke force of 158.3 N at 6 bar pressure. Constructed with anodised aluminium and high-alloy stainless steel, it's suited for moderate corrosion environments (CRC class 2) and conforms to cleanroom class 6 standards. The G1/8 pneumatic port and proximity switch compatibility make it integration-friendly for modern automation setups.
Applications of Festo Round Cylinder DSNU-12-70-P-A
The DSNU-12-70-P-A is widely used in scenarios that demand precise and consistent linear motion over a longer stroke. One common use is in packaging lines, where it helps push or separate items on a conveyor without jerks or delays. Its compact round body allows for easy installation in tight spaces, making it suitable for machinery with limited clearance.
In assembly fixtures, this cylinder is used for controlled pushing or pressing operations, such as positioning components for screwing or welding. Thanks to its compatibility with proximity switches, it provides feedback for accurate positioning, which is essential in automated cycles. For maintenance engineers, it’s a reliable choice due to its low wear rate and standard design. For students, this cylinder demonstrates fundamental pneumatic principles in practical lab settings.
Its predictable behavior, ease of installation, and support for sensors make the DSNU-12-70-P-A a smart choice for both new designs and retrofit automation systems.
