4-035-01-2297 Pneumatic Cylinder 4035012297 Spares for Homag Woodworking Machine

When a Homag machine loses hold, check the cylinder before anything else. A worn bore or a bent rod on a 400 mm stroke unit shows up as drift, a weak clamp, or a stroke that stops short. Replacing the cylinder with 4-035-01-2297 puts the motion back where the machine expects it.

This is an air cylinder with a 25 mm piston diameter and a 400 mm stroke. The piston rod thread is M10x1.25 and the pneumatic connection is G1/8. It is a spare for Homag machine use. Confirm the fit against your parts book entry 4035012297 and against the numbers stamped or cast on the cylinder you are removing.

Look at the rod thread first: M10x1.25 takes an M10x1.25 nut or clevis, so a mismatched thread will not seat. Ports are G1/8, so your fittings must match that thread. On a 400 mm stroke, rod alignment through the full travel matters; a side load shortens seal life.

Stock is ordered as 4-035-01-2297 Pneumatic Cylinder 4035012297, shipped by DHL, FedEx, UPS, etc. Send the Homag part number, the 400 mm stroke and 25 mm piston diameter, plus a photo of the old cylinder's rod end and ports, so the match is checked before dispatch.

What the specification fixes, and what it leaves to the machine:

• Confirming the fit — Match 4035012297 and the 25 mm piston diameter against the parts book entry before ordering, since a wrong bore will not clamp right.
• Rod thread wear point — The piston rod thread is M10x1.25, so inspect the old rod end for thread damage before you fit the new cylinder.
• Stroke length on the machine — A 400 mm stroke sets how far the mechanism travels; measure the old cylinder's extended length to confirm it is the same unit.
• Air line connection — Pneumatic connection is G1/8, so check the fitting on the existing air line matches G1/8 before you disconnect anything.
• Installation check — Align the rod through the full 400 mm travel when mounting, because side load on the rod works the seals harder.
• Bore size and force — Piston diameter is 25 mm, so the force you get depends on that bore and your line pressure, not on the part number alone.
• Spare for Homag machines — Keep one on the shelf as a spare for Homag machine use, so a failed cylinder does not stop the line for a shipping wait.

What changes on the shop floor when the right part goes back in:

• Get the machine moving again. A failed cylinder stops a clamp or feed motion, and a replacement with the same 400 mm stroke and 25 mm bore puts the machine back to its original travel without shimming or adapting the mounts.
• Threads that match the fittings you already have. With M10x1.25 on the rod and G1/8 at the ports, the existing nut and air fittings go back on, so you avoid hunting for adapters while the machine sits idle.
• Check the fit in one place. The 400 mm stroke, 25 mm piston diameter, M10x1.25 rod thread and G1/8 ports are all stated up front, so you compare them to your parts book before the order goes out.
• Order by the number, not by looks. Quoting 4-035-01-2297 and 4035012297 together ties the order to the Homag reference, which cuts the chance of a lookalike cylinder arriving with the wrong stroke.
• Keep a spare within reach. Holding one cylinder as a spare for Homag machine use means a worn seal or bent rod is a swap, not a wait for a courier to arrive from overseas.
