ParkerHeavy Duty NFPA Tie Rod Pneumatic Cylinder, 1-1/2 in Bore, 1.5 in Stroke, Double Acting, 250 psi

Product Description

What this part is

Parker 1.50B B 2ALU18A 1.500 heavy-duty tie rod cylinder from Series 2A, supplied under Parker order number 1H2A0000287908. Series 2A is Parker’s square-head industrial air cylinder line, built on four tie rods drawing the head and cap against the barrel. Manufacturer: Parker. Part Number: 1H2A0000287908. Model Number: 1.50B B 2ALU18A 1.500. Series: 2A. Bore: 1-1/2 in. Stroke: 1.5 in. Actuation: double acting. Nominal Pressure: 250 psi air service. Medium: filtered compressed air. Standard: ANSI/NFPA T3.6.7 R2-1996 square head industrial fluid power cylinders.

Decoding the designation

1.50B — 1-1/2 in bore.

2A — Series 2A, the heavy duty NFPA air cylinder line rated for 250 psi air service.

1.500 — 1.5 in stroke, written to three decimal places as Parker writes every inch stroke.

1H2A0000287908 — the Parker order number carried on the nameplate alongside the model number.

What these specs mean in practice

Bore: 1-1/2 in. Nominal Pressure: 250 psi. A 1-1/2 in piston at 80 psi shop air develops roughly 140 lbf on the extend stroke, and the 250 psi rating leaves the cylinder well inside its envelope at normal plant supply. Stroke: 1.5 in. A stroke equal to the bore is short-throw geometry: clamping, indexing, gating and stop duty rather than transfer, and rod column strength is a non-issue at this length. Actuation: double acting. Both directions are powered, so the retract stroke can do work rather than merely reset. Standard: ANSI/NFPA T3.6.7. Conforming to the NFPA square head standard means the envelope, port positions, rod extension and mounting hole pattern match every other NFPA 1-1/2 in bore cylinder, so the cylinder drops into an existing machine frame without rework.

Mounting data

Standard: ANSI/NFPA T3.6.7 R2-1996. Bore: 1-1/2 in. Series 2A is published across 17 standard mounting styles and rod diameters from 1/2 in to 5-1/2 in, all sharing the NFPA square head interface for the bore.

Interchange guidance

1H2A0000287908 is the Parker order number and 1.50B B 2ALU18A 1.500 is the model number; both identify this cylinder. Parker Series 2A model numbers read bore first, mounting and rod configuration in the middle, stroke last, so a 2A cylinder of the same bore and mounting differing only in the trailing figure differs only in stroke.
