Piston Rod Thread: M16 x 1.5, external. Port Size: G3/8, internal thread. Working Pressure: 1.5 to 10 bar. Cushioning: pneumatic, adjustable, with elastic end cushioning. Piston: magnetic. Weight: 3.15 kg. Overall Body Length: 441 mm.

Decoding the order code

0822123009 — Bosch Rexroth material number. Within the PRA table, 0822123xxx is the 63 mm bore column and the trailing 009 is the 320 mm stroke row.

PRA — Rexroth’s ISO 15552 profile-barrel standard cylinder range.

063-0320 — the shorthand carried on the carton: 63 mm piston diameter, 320 mm stroke.

DA — double-acting, the execution supplied across this table.

BAS — the base execution of the range, magnetic piston with adjustable pneumatic cushioning at both ends.

What these specs mean in practice

Extending Piston Force at 6.3 bar: 1960 N. Retracting Piston Force at 6.3 bar: 1765 N. Rexroth quotes PRA forces at 6.3 bar rather than 6 bar. The 63 mm bore keeps the same 20 mm rod as the 50 mm, so the extend-to-retract gap narrows as the bore steps up.

Cushioning Length: 16.5 mm. Cushioning Energy: 27 J. At 320 mm of travel that energy figure is the number to size against, because a long stroke lets the load build velocity before it reaches the cushion.

Maximum Stroke for the 63 mm Bore: 2500 mm. Working Pressure: 1.5 to 10 bar. Ambient Temperature: −20 to +80 °C. Medium Temperature: −20 to +80 °C.

Medium: compressed air. Maximum Particle Size: 50 µm. Oil Content of Compressed Air: 0 to 5 mg/m³, held constant over the life of the cylinder. Pressure Dew Point: at least 15 °C below ambient and medium temperature, and no higher than 3 °C.

Material, Cylinder Tube: anodised aluminium. Material, Piston Rod: stainless steel. Material, Front Cover and End Cover: die-cast aluminium. Material, Seal and Scraper: polyurethane. Material, Piston Rod Nut: galvanised steel.

An ATEX execution of this cylinder is published under ATEX ID II 2G2D c T4 T135 °C with an ambient range of −20 to +60 °C.

Mounting data

Body Length at 0 mm Stroke: 121 mm ±0.8. Rod Extension Beyond the Front Cover: 37 mm. Piston Rod Thread Length: 32 mm. Across Flats on the Rod: 17 mm. Spigot Diameter: 45 mm to d11. Spigot Length: 16 mm. End Cap Width: 75 mm. Tie-Rod Thread: M8. Cover Tapped Hole: M10. Mounting Hole Centre Distance: 56.5 mm ±0.7. Port Centre Offset PL: 24 mm. L2: 25 mm. Piston Rod Diameter Tolerance: 20 mm f8.

The barrel carries ISO 15552 sensor grooves, so magnetic proximity switches mount flush along the body. Standard ISO 15552 accessories for the 63 mm bore — foot, front and rear flange, rear clevis, trunnion, rod clevis and rod eye — fit this envelope.

Quantity and configuration

Unit Quantity: 1 Pc. Cylinder only.

Interchange guidance

The mounting interface, G3/8 ports, 20 mm rod and M16 x 1.5 rod thread are the ISO 15552 standard for a 63 mm bore, so this cylinder is dimensionally interchangeable with a Festo DNC-63-320-PPV-A, an SMC C96SB63-320C, a Norgren PRA/182063/M/320 or a Parker P1D-B063MS-0320 on brackets and porting. Within the Rexroth table, 0822123008 is the same cylinder at 250 mm stroke and 0822123010 at 400 mm; 0822122009 is the 50 mm bore at 320 mm stroke and 0822124009 the 80 mm bore at 320 mm.
