HA-655-1-200 / FHA-17C-160 / D250 / CK / SP — Pneumatic & Hydraulic Cylinder

FLUID POWER ACTUATOR · 65 MM BORE · 200 MM STROKE · FLANGE MOUNT · 90-DAY WARRANTY

The composite part number HA-655-1-200 / FHA-17C-160 / D250 / CK / SP is a fluid-power actuator widely used in factory automation cells. KOEED lists it as a hard-to-find replacement for legacy machine-tool, packaging and assembly fixtures. Because the suffix string can be parsed more than one way, the KOEED engineering desk decodes the most likely interpretations below and asks the buyer to confirm a few measurements before shipping.

The unit ships in reinforced export packaging via DHL or FedEx with a 90-day functional warranty. For multi-line quotes, attach a photo of the data plate and send the full instrument list to Moritta@KOEED.COM and the desk replies within 24 business hours.

Key Technical Specifications & Overview

The P/N string embeds three independent codes: HA-655-1-200 is the actuator body call-out, FHA-17C-160 describes the front-head / flange assembly, and the trailing options D250 / CK / SP define the bore, porting and return mode. Because the same combination is reused by several fluid-power vendors, KOEED maintains the part on a live stock ledger that is updated after every test bench cycle.

Most-likely interpretations

• Pneumatic cylinder, double-acting with spring return — HA-655 = 65 mm bore compact ISO cylinder, 200 mm stroke; FHA = front-head assembly, 17C-160 = 17 mm rod, 160 bar-rated seal kit; D250 = 250 mm overall length; CK = cross port (G1/4"); SP = spring return.
• Hydraulic actuator with front flange mount — HA = hydraulic actuator, 655 = 65 mm bore single-rod, 1 = single-rod, 200 = 200 mm stroke; FHA-17C = front flange mount, 17C-160 = 16 bar housing pressure class; D250 = 250 mm component envelope; CK = cross port; SP = set-point adjustment.
• Clamping / index-table cylinder (compact ISO 15552 profile) — HA-655-1-200 = ISO 15552 65 mm bore 200 mm stroke; FHA-17C-160 = FHA front-head with 17 mm rod, 160 mm pivot pin; D250 = 250 mm pivot-to-pivot mounting; CK = cross port; SP = spring-return for fail-safe operation.

Application Scenarios — Where It Fits

The 65 mm bore / 200 mm stroke envelope is the workhorse of mid-range fluid power. KOEED ships this actuator into factory automation cells driven by Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE controllers.

• Machine tool: tool-change arms, part clampers, sliding guards, door interlocks on CNC lathes and machining centres.
• Packaging lines: pusher fingers, index gates, hot-melt gun swings, conveyor diverters on horizontal form-fill-seal machines.
• Automotive body-in-white: fixture clamps, weld-gun counter-balance, hemming assist and lifters on robotic weld cells.
• Mobile equipment & AGV: tailgate lifts, bin stops, lifting pins and stabiliser legs on automated guided vehicles and electric lift trucks.
• Fluid-power clamping & work-holding: zero-point pallet clamping, hydraulic vise actuation, spring-return fail-safe for press brakes.
• Index tables & assembly: 4-station / 8-station rotary indexers, dial conveyors and small-parts escapements.
• Conveyor diverting: pneumatic pusher, swing-arm diverter, cross-belt sorter actuation in parcel handling.

The spring-return (SP) option makes the part attractive for fail-safe applications where loss of air or hydraulic pressure must return the load to a safe rest position. See the PLC error-code database for fault patterns when the downstream controller reports an actuator timeout, or the AI diagnostic tool for nameplate-based identification of near-equivalent units.

Integration & Wiring Notes

This is a fluid-power device, not an electrical module — it carries no signal wiring. The integration discussion therefore covers the pneumatic / hydraulic circuit side and the discrete I/O that the upstream PLC uses to command the solenoid valve.

When the actuator is part of a larger machine retrofit, KOEED can also source the solenoid valve, FRL, fittings and proximity switches as a single BOM — see China sourcing capabilities for the full parts pipeline. Cabling, conduit and fieldbus are deliberately excluded; KOEED supplies the actuator assembly, not the cabinet wiring.

Installation & Commissioning Tips

• Inspect before mount: compare the body diameter, rod diameter, pivot length and overall length against the data plate. A 60 mm bore or 16 mm rod will physically fit but mechanically drift — reject before commissioning.
• Align before tightening: flange-mount (FHA) variants need the mating face flat within 0.05 mm; misalignment loads the rod bearing and causes premature seal wear. Use dowel pins on the flange bolt pattern.
• Clean air / oil first: flush the supply line and pre-fill with the working medium; debris entering the cylinder is the most common cause of early seal failure.
• Cushioning: check the cushion needle setting on both end caps; a too-fast final stroke into the spring-return (SP) end will hammer the end cap.
• Cycle test: run 10–20 full strokes at low pressure before the line goes into production. Listen for hiss, watch for drift, and confirm end-of-stroke position feedback within the PLC scan.
• Torque and lock: pivot-pin nuts use the manufacturer spec; apply thread-locker if the application vibrates. Re-torque after the first 50 hours.
• Document the install: photograph the data plate and the final assembly; this makes any future warranty claim or re-order unambiguous.

Procurement, Warranty & Lead Time

The HA-655-1-200 / FHA-17C-160 / D250 / CK / SP part number is a composite / ambiguous call-out. KOEED routinely sources it from several fluid-power partners in the KOEED network, but the engineering desk must confirm the physical unit before issuing a binding quote.

What to send to confirm fit

• A clear photo of the data plate (serial, body code, porting).
• One photo of the cylinder body with a tape measure showing overall length and the 250 mm reference (D250).
• One photo of the rod end and the front flange (FHA) bolt pattern.
• Operating medium (air or oil), working pressure, and any spring-vs-double-acting preference.
• Quantity and required delivery window.
