Product Description

What this part is

Norgren PRA/182063/M/125, a double-acting profile pneumatic cylinder to ISO 15552. Bore: 63 mm. Stroke: 125 mm. Piston Rod Diameter: 20 mm. Piston Rod Thread: M16 x 1.5. Port Size: G3/8. Operating Pressure: 1 to 16 bar (14 to 232 psi). Cushioning: pneumatic, adjustable at both ends. Piston: magnetic. Product Weight: 2.45 kg. Body Length at 125 mm Stroke: 246 mm.

Decoding the designation

PRA — Norgren’s ISO 15552 profile-barrel cylinder range, double-acting with adjustable end cushioning.

182 — the 182000 series within that range.

063 — bore diameter in millimetres.

M — magnetic piston, so the stroke ends can be picked up by reed or solid-state switches sitting in the profile grooves.

125 — stroke in millimetres.

What these specs mean in practice

Theoretical Thrust at 6 bar, Outstroke: 1870 N. Theoretical Thrust at 6 bar, Instroke: 1680 N. At the 16 bar ceiling the same bore develops proportionally more, which is what puts a 63 mm PRA into clamping and pressing duty that a 10 bar cylinder of the same size will not cover.

Air Consumption at 6 bar, Outstroke: 0.218 litres per centimetre of travel. Air Consumption at 6 bar, Instroke: 0.195 litres per centimetre. Over a 125 mm stroke that is roughly 2.7 litres out and 2.4 litres back per cycle at 6 bar.

Cushion Length: 24 mm. Initial Cushion Volume: 64 cm³. Cushioning is set by a screw at each end cap, so deceleration is tuned to the moving load.

Operating Temperature: −20 to +80 °C. Medium: compressed air, filtered, lubricated or non-lubricated.

Material, Profile Barrel: anodised aluminium. Material, End Covers: pressure die-cast aluminium. Material, Piston Rod: martensitic stainless steel. Material, Piston Rod Seals and Piston Seals: polyurethane. Material, O-Rings: NBR.

Conforms to Standard: ISO 15552, and to ISO 6431, VDMA 24562 and NFE 49-003-1, which share the same mounting envelope.

Mounting data

Body Length at 0 mm Stroke: 121 mm. Rod Extension Beyond the Bearing Cap: 37 mm. Piston Rod Thread Length: 32 mm. Across Flats on the Rod: 17 mm. End Cap Width: 75 mm. Tie-Rod Thread: M8. Mounting Hole Centre Distance on the End Cap: 56.5 mm. Spigot Diameter: 45 mm to e11.

Matching ISO 15552 mountings for the 63 mm bore: foot bracket QA/8063/21, front flange QA/8063/22, rear clevis QA/8063/23, rear eye QA/8063/27, detachable trunnion QA/8063/34, adjustable trunnion PQA/182063/40, rod clevis QM/8050/25, universal rod eye QM/8050/32, universal rear eye QA/8063/33, and stud mounting QM/8050/35. Service kit: QA/8063/00.

Switch mounting: M/50 series reed and solid-state switches sit flush in the profile grooves. Reed types run 10 to 240 V AC or 10 to 170 V DC at 180 mA maximum, IP66. Solid-state PNP and NPN types run 10 to 30 V DC at 150 mA maximum, IP67.

Quantity and configuration

Unit Quantity: 1 Pc. Cylinder only.

Interchange guidance

PRA/182063/125 is the same cylinder with a non-magnetic piston, identical on every mounting dimension and force figure. PRA/182063/MW/125 drops the adjustable cushioning. PRA/182063/X4/125 is the low-friction execution without cushioning, restricted to 1 to 10 bar on filtered non-lubricated air. Any ISO 15552 63 mm cylinder matches on the mounting interface, G3/8 ports, 20 mm rod and M16 x 1.5 rod thread, so the deciding differences against another maker are the 16 bar rating, the polyurethane seal set and the flush groove switches.
