4-035-01-2583 CYLINDER AMS D 40 HUB 140 G1 8 Tools For Homag Woodwork Machine

A double-acting pneumatic cylinder for Homag woodworking machines, part number 4-035-01-2583. It has a 40mm bore and a 140mm stroke, with G1/8" threaded ports. The body is anodized aluminum and the piston rod is stainless steel. To confirm fitment, compare the 40mm bore and 140mm stroke against the cylinder you are replacing, check that the ports are G1/8", and verify the double-acting single-rod configuration matches the machine's current setup.

When a Homag machine's clamp, stop, or transfer cylinder stops holding position or starts leaking at the seals, the machine may fault out or produce inconsistent cuts. The 4-035-01-2583 cylinder is the replacement for that specific pneumatic function, restoring the 140mm stroke and 40mm bore that the machine's control expects.

This is a double-acting, single-rod cylinder. The body is anodized aluminum with a stainless steel piston rod, and the ports are G1/8" threaded. It fits Homag woodworking machines that use the 4-035-01-2583 cylinder. Confirm the fit by matching the 40mm bore, 140mm stroke, and G1/8" port size against the cylinder currently on the machine.

Check the mounting pattern and rod-end thread on the old cylinder before ordering. The G1/8" ports accept standard fittings, so existing air lines can be reused if they are in good condition. Because the cylinder is double-acting, it needs air on both ports to extend and retract; a single-acting circuit will not operate it correctly.

These cylinders are packed as individual spare parts. No customisation or special packaging is offered unless stated in your order confirmation. When you enquire, send the part number 4-035-01-2583, the machine model, and a photo of the old cylinder's mounting and rod end so the fit can be checked before dispatch.

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

• Bore size for clamping force — The 40mm bore matches the original cylinder's clamping force, so the machine's existing pressure settings do not need to be changed.
• Stroke length for travel — A 140mm stroke gives the same travel as the original cylinder, keeping the clamp or stop position consistent through the machine cycle.
• Port size for air fittings — G1/8" threaded ports accept standard push-in or barbed fittings, so existing air lines can be reconnected without adapters.
• Rod material for wear — The stainless steel piston rod resists rust and scoring, which helps the rod seal last longer in a shop-floor environment.
• Body material for weight — Anodized aluminum keeps the cylinder body light while providing a surface that resists corrosion from moisture in compressed air.
• Double-acting operation — Air on both ports extends and retracts the rod, so the cylinder can push and pull under control rather than relying on a spring.
• Single-rod design — The single-rod layout matches the mounting space on the machine, with one rod end for attaching the clamp or linkage.
• Part number for ordering — 4-035-01-2583 and 4035012583 both identify this cylinder, so you can order using whichever number is on your parts list.

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

• Direct replacement for the original function. Because the bore and stroke match the 4-035-01-2583 cylinder, the machine's clamping or stop position stays the same, so you avoid re-teaching positions after the swap.
• Air lines reconnect without adapters. G1/8" ports match the standard fitting size on the machine, so you can reuse existing fittings and hose, cutting installation time and avoiding a hunt for adapters.
• Stable force through the stroke. A 40mm bore with a 140mm stroke gives consistent force over the full travel, so the clamp holds the same way at the start and end of the stroke.
• Rod resists shop-floor wear. The stainless steel rod stands up to moisture and chips better than a plain steel rod, reducing the chance of scoring that damages the rod seal.
• Light body, less mounting stress. Anodized aluminum keeps the cylinder body light, which puts less load on the bracket and mounting bolts during fast cycling.
• Controlled retract as well as extend. Double-acting operation means air drives the rod both ways, so the clamp releases with force rather than relying on a spring that can weaken.

Match the 40mm bore, 140mm stroke, and G1/8" ports against the cylinder on your machine. Also check that the old cylinder is double-acting with a single rod, and compare the mounting pattern and rod-end thread before ordering.

Yes, this is the 4-035-01-2583 cylinder, also written as 4035012583. The bore, stroke, port size, and double-acting single-rod configuration match that part number.

G1/8" is the thread size for the air ports. Standard G1/8" fittings will thread in, so you can usually reuse the fittings and hose from the old cylinder if they are undamaged.

No, this is a double-acting cylinder and needs air on both ports to extend and retract. A single-acting circuit with one air line will not operate it correctly.

The bore is 40mm and the stroke is 140mm. Those are the two dimensions to compare with the old cylinder before you order.

The body is anodized aluminum and the piston rod is stainless steel. The aluminum body keeps weight down, and the stainless rod resists rust and scoring.

Send the part number 4-035-01-2583, the machine model, and a photo of the old cylinder's mounting and rod end. That lets the fit be checked against the 40mm bore, 140mm stroke, and G1/8" ports before dispatch.

Packing is standard for this spare part, and no customisation is offered unless it is stated in your order confirmation. Ask about any special requirement when you send the enquiry.
